  • 2. How much does it cost?
     

    Most downloadable data is priced based on 500m x 500m tiles. For most orthophoto, the cost is $70 per 500m tile, and $150 per 1km tile, with progressive discounts applied automatically for orders greater than 5 tiles. Contours are $60 per tile. DEM are $60 per tile in Golden Horseshoe and $30 per tile for the Simcoe-Kawartha dataset.

    Teranet parcels are $77 per tile at a flat rate, regardless of the number of parcels contained in the 500m square area. Property mapping can also be purchased as a custom order at $13 per parcel plus labour, with progressive discounts for orders over 10 parcels.

    For Ontario Base Mapping, each map sheet is priced based on file format. View-only PDF or print copies are $15. Georeferenced raster copies (GeoTiff format) are $30. GIS and CAD formats are $100 per map sheet.

    For Floodplain mapping, PDF maps are $30, CAD formats are $125 each.

    Subscription based services such as VuMAP are priced based on the number of users, starting $1500 per year. MapCast subscriptions are priced based on bandwidth, starting at $500 per year for 500MB of bandwidth per month.

  • 6. How often is data updated in MapWarehouse?
     

    Update cycles are different for each type of data.

    Parcel data has a regular quarterly update, although not every update is clipped into tiles and made available on MapWarehouse. To access to most current parcel data, make a custom order by contacting customer service.

    Orthophoto are captured by aircraft during March, April and May each year, after the snow pack is melted but before foliage obscures the ground, usually based on the limits of county boundaries. Not every county will be flown each year. The images captured in the Spring are processed during the Summer and Fall and made ready for sale on MapWarehouse by Winter.

    Other data sets including elevation data, OBM, floodplain mapping and moraine groundwater mapping are available on an "as is" basis and do not have regular updates.

  • 7. I got spatial data from the City of Toronto, but FBS's data doesn't line up, it's shifted east by 300,000km. How do I fix this?
     

    FBS data is usually in UTM NAD83 Zone 17N. City of Toronto offers their data in MTM NAD27 Zone 10. Some of the files may need to be re-projected into to a common coordinate system in order to align properly, a simple procedure for vector files. If you require imagery to be reprojected, however, contact customer service. A fee for custom labour will apply.

  • 8. How is the data projected? Can I change the projection to suit my project?
     

    Data is in UTM NAD83(original) in most cases, Zone 17N unless otherwise specified. While converting datum and projection settings for vector files is a simple task for most users, the same operation with raster data like orthophoto may require a higher level of expertise. Conversion to other datums such as MTM NAD27 Zone 10, which is typical for City of Toronto data, is a service FBS can provide. A fee for custom labour would apply. Contact us for a quote.

  • 11. How do I choose more than 200 tiles?
     

    For large orders, the best option is to contact customer service with a SHP file delineating the area you would like quoted and let us know which data sets and file formats you're most interested in. You will receive a quote to sign and return. You can also send us the boundaries of the specific tiles you'd like to order using the tile indexes.

  • 12. What can I do with the downloadable tile indexes?
     

    Lots! The tile indexes are georeferenced vector files in SHP or KML format and can be downloaded for each dataset via the coverage map. These can be used in your own software to see the context of where the tile boundaries fall in relation to your existing data. You will be able to see at a glance how many tiles you will need to cover your area of interest. You can identify the tiles from the index you'd like to order, and use the itemID or filename information in the associated table to select the tiles on MapWarehouse.

    You may also select and export a subsection of an index as a new shape file and forward it to our customer service staff as your ordering polygon when requesting a quote. This not only helps us get the quote to you quickly, it also allows you to keep the exact boundary of your area of interest confidential.

  • 17. Is there anything newer?
     

    We update large portions of our aerial imagery every year to keep up with demand for new data, especially in suburban areas where land development is taking place. In the built environment, the imagery will be different every single year, so it's worth the effort to fly the same areas over and over.

    The same is true for many types of "cultural" features such property line boundaries. Not every parcel changes every year, but within our large database covering all of Ontario, enough parcels change to need scheduled updates to maintain the relevance of the information a few times a year.

    Not so, however, with other types of mapping. One of our most popular data products is elevation mapping which was produced in 2002. Since our DEM and contour mapping is looking at bare earth topography, and the lay of the land doesn't generally change, there's no reason to update the data based solely on its age.

    There are a few exceptions. Activities that change the landscape such as mining, dam building, and urban expansion would require an updated map if those activities took place at your area of interest since the DEM was produced in 2002.

  • 1. What’s MapCast?
     

    MapCast is a live, on-demand connection to First Base Solutions' complete library of high-resolution orthophotography and elevation contours served directly into your CAD or GIS workstation. It’s a Web Mapping Service (WMS); a standard protocol used for serving georeferenced map images over the Internet. Once you connect MapCast into your WMS compliant software, the aerial imagery base layer will load into your mapping project in a similar way as data layers you store locally. Having an external data source available through a WMS like MapCast reduces internal network loads and the costs associated with data storage and management. It is an efficient and cost effective way for organizations to access large data sets, reduce network overhead, and avoid data purchase, management and update costs. First Base Solutions handles it for you.

  • 9. Is bandwidth usage for contours the same as for imagery?
     

    Yes, all data transferred through the MapCast WMS subscription is tracked the same way.  However, the size of the file will vary depending on the data contained, so in general, the contours would contain less data (colours) than an orthophoto image and therefore use less bandwidth.

  • 10. How can I make the most of my bandwidth?
     

    There are several options:

    1. Turn off the MapCast layer off when panning and zooming.
    2. Turn the MapCast layer off when zoomed out to smaller scales beyond 1:10,000.
    3. In CAD, choose the resample raster option to crop the imagery to your view so excess imagery will not draw when you zoom out.
    4. In ArcMAP, choose the cache option to avoid reloading the image when turning the MapCast layer off and on.
    5. Make sure that only the relevant imagery set for the study area is active and turn all others off.
    6. Select “jpeg” for the image format to reduce the size of the image requested.
    7. Decrease the size of the image being requested by making your application window smaller.
    8. Wait for the MapCast layer to draw completely before requesting a new image.

  • 12. How is bandwidth measured?
     

    Users on MapCast with WMS compliant software can request an image that will match the screen resolution or scale of the software’s window. The request is sent through the Internet to the FBS servers where the image is generated and then returned to the user to be displayed in the software’s window. This action will count as one image, each time the user refreshes, pans or zooms in or out on the software’s window, an image will be generated and counted against the bandwidth monthly limit. The maximum image size returned by the service is 2048 x 2048 pixels.

  • 8. There are so many imagery layers! How can I tell which one I'm seeing?
     

    The layers will draw in the order you see them in the layers list, drawing the bottom most visible layers in the list, then drawing the visible layers above it over top. Since the imagery is opaque and completely covers an area, it will hide any layers that have drawn below it. In the image below, only the 2015 imagery can be seen even though the 2013 imagery is also visible.

    It's a good idea to keep imagery layers at the bottom and put points, lines, and areas such as roads and property lines at the top. You can adjust the order the layers draw in by using the up and down arrows below the layer's name.

  • 9. I've turned on some layers but nothing is drawing. Why?
     

    There are two reasons why this may occur.

    1. Some layers are too detailed to draw when you are zoomed out to view a large area. Below the name of each layer, you'll see "Zoom Levels: [#-##]" which indicates how close you need to be zoomed in before the layer will start to draw. You can see your current zoom level at the top centre of the map, 1 being the farthest out, 20 being the closest in. Zoom in so your map is within the zoom level range indicated by the particular layer to see it draw.

    2. Not all layers cover all geographic areas. Check the coverage map to see the geographic extents of each individual layer. If your area of interest falls outside the layer's highlighted area, there won't be any data to draw.

  • 2. Is orthophoto different from aerial photo?
     

    Yes. Orthophoto is produced by manipulating aerial photo to correct for movement of the aircraft and variations in the camera angle. Orthophoto has a top-down perspective and uniform scale, just like a map. Aerial photos are the original, unprocessed images. While they appear to be taken from an overhead viewing angle, they will inherently contain small distortions and can not be used as a map to accurately measure distance and direction like the orthophoto can.

  • 3. What does the photo resolution in cm mean?
     

    Resolution in cm refers to the area on the ground covered by each pixel in the image. In an image with 15 cm resolution, for example, each pixel covers a patch of ground 15cm x 15cm in size. Objects on the ground which are smaller than that size will not be clearly visible in the image. In general, the smaller the resolution size, the more detail can be seen in the image.

  • 4. What's the positional accuracy of the orthophoto?
     

    It depends on the photo resolution. Whatever the stated photo resolution in cm, positional accuracy is double that value. A 15 cm photo, for example, has positional horizontal accuracy of +/- 30 cm. This means that for any point on the photo, the true location of that point on the ground will be within 30 cm of where it is located in the photo.

  • 5. What's the difference between JPG and MrSid? What file format is best for my project?
     

    JPG and MrSID are just a few compressed image formats. Both formats can be read by most up-to-date CAD and GIS software. JPG is a fine option where the goal is simply to view the imagery across as many platforms as possible and use it as a base layer to give context to your vector files. MrSID is the prefered choice where more demanding image manipulation or analysis will be involved and the resulting output needs to retain the data quality characteristics of the original.

    JPG offers a reasonable balance between file size and image quality, and is most useful for images with smooth transitions between tone and colour. For this reason, JPG is easily the most popular format in digital photography and can be used with countless types of software . It does not hold up well to image processing or multiple edits, however, and can tend to lose detail of colour variation, causing a blocky appearance after decompression and recompression (posterization). FBS offers georeferenced JPG imagery by using an auxiliary *.WLD world file, which references the coordinates where the image tile should be inserted in the map, read by geo-capable software.

    MrSID (multiresolution seamless image database) is a technology owned by LizardTech specifically for use with georeferenced imagery like orthophoto, which could have up to 8 - 16bit multispectral bands. The file size can be compressed up to 20:1 without degrading the image's appearance for RGB. Using MrSID format therefore allows very large files to be viewed quickly without the need to fully decompress the image. Furthermore, metadata like pixel resolution is inherent in the image and is updated automatically during processing.

  • 6. How do I place my orthophoto in CAD software to align with other data tiles I bought?
     

    For some users, simply change the extension of the world coordinate file that came with your JPG photo from *.wld to *.jgw, or, use a utility to read the wld file, which references coordinates of the top left corner of each image, accounting for a small buffer around the photo.

    For some users, in the task pane, connect to data, add raster image or surface connection, choose the folder and files and add them to the map.

    To insert a single image, create a new layer and use the coordinates that are embedded in the file name (see Q&A below) using the command, IMAGEATTACH to insert a single image. Use the easting value for the X-coordinate and add two zeros to the end, use the northing value for the Y-coordinate and add two zeros to the end. The scaling factor is 500, because a single tile is 500m x 500m. Use the command CDORDER to change the image drawing order to the back, behind your text and linework. The image will be attached as an Xref, so use the command ETRANSMIT to package your work if you intend to share your DWG file.

  • 7. What do the numbers in the file name mean?
     

    The first letters tell the data type, "orth" for orthophoto, "line" for a digital elevation model, "contour" for contour lines. The next 2 numbers are the UTM zone, usually 16, 17, or 18, for Ontario. The next 4 numbers are the easting value of the bottom left corner of the file, the next 5 numbers are the northing value for the bottom left corner of the tile. The next 4 digits are the year the data was captured. The last letters are the data owner, "fbs" for first base solutions, "tera" for teranet. For example, if the file name is orth171234567892012fbs.jpg. This is an orthophoto, taken by First Base Solutions in 2012. The UTM zone is 17, the X-value is 123400 and the Y-value is 5678900 for the lower left corner of the tile.

    ArcExplorer is a free viewing platform with limited capabilities compared to the licensed versions of Arc software. Auxillary files containing coordinate system information (*.sdw for MrSID files) can not be read by ArcExplorer. Extent and coordinate system information must be embedded in the main file directly; this is normally achieved via ArcCatalog.

    No. The topographic displacement where you might see the side of a tall building in the photo may seem deceiving, but orthophoto by definition have been rectified to remove perspective. Without two camera angles, stereo viewing won't work. The original uncorrected imagery can be retrieved upon request.

  • 23. Is there anything newer?
     

    We update large portions of our aerial imagery every year to keep up with demand for new data, especially in suburban areas where land development is taking place. In the built environment, the imagery will be different every single year, so it's worth the effort to fly the same areas over and over.

    The same is true for many types of "cultural" features such property line boundaries. Not every parcel changes every year, but within our large database covering all of Ontario, enough parcels change to need scheduled updates to maintain the relevance of the information a few times a year.

    Not so, however, with other types of mapping. One of our most popular data products is elevation mapping which was produced in 2002. Since our DEM and contour mapping is looking at bare earth topography, and the lay of the land doesn't generally change, there's no reason to update the data based solely on its age.

    There are a few exceptions. Activities that change the landscape such as mining, dam building, and urban expansion would require an updated map if those activities took place at your area of interest since the DEM was produced in 2002.

  • 2. What's the difference between contours and DEM?
     

    The DEM capture was produced from 2002 orthophoto at 1:10,000. It includes elevations on a 40m grid spacing together with break lines along all visible terrain impacting features (road edges, drainage, etc.) The DEM is a representation of a topographical surface, specifically a regular grid of spot heights and break lines (noticeable changes in slope). The file is available in UTM NAD83 in DWG format. The DEM does not contain contours, but they can be generated from the DEM.

    The contour file is a separate product that is derived from the DEM. The contour interval is 1m.

    If you have the software to generate contours from the DEM, then all you would require is the DEM and produce the contours yourself. The contours became available for those users who do not have this software ability.

    In the Golden Horseshoe data set, the horizontal and vertical accuracy is +/- 40 cm, and +/- 80 cm for the Simcoe-Kawartha data set. This means that the difference between the true elevation on the ground compared to what's shown in the digital file can be as great as 40 cm or 80 cm. The most accurate areas will be those with excellent ground visibility in the source orthophoto which the elevation model was derived from. Areas with dense forest, especially coniferous forest where the ground is obscured, tend to have the lowest accuracy.

  • 6. I thought I was getting a complete map but this file is just a bunch of lines. Where are the road labels and other features?
     

    Only elevation information is included, either as DEM or contour, depending on the file you've chosen. The road edges frequently appear as break lines in the DEM, giving the appearance of unlabeled roads. There are a few options to give context to to the surrounding area. You can take advantage of the georeferencing inherent in the elevation data file and use it with your own spatial data you've collected for your project as a background layer. If you don't have your own data, the tile grid for elevation data coverage is the same as for orthophoto and Teranet parcel coverage. Users often purchase a few files of different data types for the same grid cell. The user can then use the orthophoto as a background layer and add elevation data on top, both files having identical geographical coverage. In this way, users can select data a la carte and pay for only the layers and coverage needed.

  • 6. Why doesn't the property boundary line up perfectly with the orthophoto?
     

    The orthophoto are generally spatially accurate to double the resolution value. Simply put, if a photo has resolution of 20cm, any point on the photo will be accurate within 40 cm of its true location. For the parcel data, different Land Registry Offices in Ontario were originally drawn to different standards and then later integrated into one dataset that's now maintained by Teranet. The most accurate being POLARIS (Province of Ontario Land Registration Information System) which is based on surveys, followed by BIM (Basic Index Mapping) which is based on 1:10,000 scale mapping or smaller, and Pre-BIM, which is compiled in areas where good control data is less available, making it the least positionally accurate. In an area where pre-BIM standards are used, it's not unusual for the property lines to be off by 10 m or more from where you would expect them to lie on the photo. Where your orthophoto and property lines don't align perfectly, it's likely due to different accuracy standards used to create one or both of the datasets.

  • 7. I've purchased adjacent tiles of parcel and they're polylines clipped at the tile boundary, but I want full parcels as polygons. How can I connect line work from adjacent tiles together to complete the parcels which cross the tile boundary into single features and/or convert the geometry to polygons?
     

    Polygons would not be a good representation of the data in this case because the geometry of the parcels is clipped to the boundary of the tiles, so the area, perimeter, and parcel boundaries of the properties on the edge of the tile would be misleading. A closed polyline indicates the entire property is included in the tile, an open polyline indicates that only a portion of the property is included in that tile, the remaining area will appear in the adjacent tile. There are several methods to convert the geometry, a few are discussed below:

    In CAD:
    Copy the line work from one file, and use the command "paste to original coordinates" to have them together in one DWG. Use the command PEDIT (polyline edit). Select M (multiple), and choose all the linework from both tiles and hit enter. You will be prompted with, "Convert Lines and Arcs to polylines?" choose Y (yes), then enter the option J (join), the join type is "extend". Enter a small fuzz distance 5 (mm). The line work from adjacent tiles will be joined into single line features.

    In ArcMap:
    To convert a polyline tile to polygons with an "Editor" license, in ArcToolbox, export the polyline file as text using "Write Features to Text File". Open the *.txt file you've created and edit the header information to read "polygon" instead of "polyline." In ArcToolbox, import the modified text file using "Create Features from Text File". A polygon shape file will be created.
    or:
    In ArcCatalog, right-click the line layer, export it as a *.dxf file. In ArcMap load this * .dxf file and it will behave like a DWG file, comprised of several layers, including a polygon file. Export the polygon file and point file and save as a shapefile. Choose the matching portions of parcels which cross the tile boundaries and merge the features. Use the "transfer attribute" tools or "spatial join" tools to transfer PIN attributes from the point file to the polygon file based on spatial location.
    or:
    Using a script, an example can be found at the link.
    or:
    Using a utility such GeoWizard, available here.

    Large properties often span several tiles, you're seeing only the portion of the parcel boundary that crosses the particular tile. You will either need to buy all the tiles that your property intersects and combine the boundary lines, or, request a quote for a custom order for the specific parcel.

  • 2. What's floodplain mapping?
     

    Floodplain mapping defines the limits of the Regulatory Floodplain for a particular watershed, used for regulatory purposes. These maps are produced and maintained by the TRCA (Toronto and Region Conservation Authority) for watercourses in the greater Toronto area, showing properties, topographic information and high water levels. Floodplain mapping was compiled photogrammetrically from 1/10,000 aerial photography flown in 2002. The vertical datum is mean sea level as established by the Geographic Survey of Canada, North American Datum, 1983, U.T.M projection Zone 17. Please Note: Floodline elevations are subject to change due to revised information. Full information can be found here on TRCA.

  • 3. How accurate is it?
     

    The information shown on this map series is subject to change. The volume of water introduced into a regional drainage system from rain and snow melt can vary wildly between different points in the system and from one storm event to another. Ground cover, slope, channel depth, meander, and soil drainage characteristics all play a role, and the accuracy of the flood predictions are in part, limited by the quality of the data and assumptions used in the hydraulic model. For these reasons, the regulations that are derived from flood modeling are often conservative, erring on the side of caution.

The hydraulic analysis performed by the Conservation Authority takes into account not just the volumetric limitations of a stream corridor, but also site specific characteristics such as soil types, and impervious material like rooftops and asphalt, which affect the rate at which a watershed can discharge surplus water and return to normal flow. The floodplain map alone can be considered an administrative tool.

  • 2. What is "Moraine Groundwater" and how do I use these files?
     

    The data was produced by the Toronto Region Conservation Authority. Each of the asc files represent the elevation you would find the various levels of substrate (e.g. Kettleby Till) along with the ground elevation and bedrock elevation. You can therefore determine the thickness of each substrate over a given location. The asc file is a raster data set similar to an image, where each pixel value represents an elevation value rather than a colour. Depending on the data set, the pixel sizes vary from 100 to 250 meters in ground resolution with each asc file covering 1km x 1km area. The individual files can be viewed with most GIS software - ArcGIS etc. TRCA has recommended an application called "VIEWLOG" which can be used to create cross sections. ViewLog website.
    There is also an open source application called Quantum GIS that can be used to view and query the files.
    First Base Solutions does not maintain or have the in house expertise to provide technical support for the CAMC data. For more in depth questions, contact the CAMC.

  • 2. How do I order satellite imagery from FBS?
     

    First Base Solutions is a licensed reseller of DigitalGlobe satellite imagery. We have access to search a library of historical satellite imagery with worldwide coverage at 50cm and 60cm resolution, as well as place orders to capture new imagery on request. Imagery is available as natural colour, greyscale, colour infrared or 8-band multispectral for use in a variety of false-colour applications.
    To request a quote for a custom order, simply submit an ordering polygon in SHP, DWG or a similar file to customer service which outlines your area of interest and let us know any specific requirements. Our customer service staff will review the various imagery options available with you. Please note, there is a minimum order size of 25 sq. km for archive imagery and 100 sq. km for new imagery, and ordering polygons must be regular shapes (rectangles or circles preferred, no doughnut holes allowed) and corridors must be buffered to at least 3km wide to locate archived imagery for you.
    Coming in 2016, selected DigitalGlobe satellite imagery will also be available to pick, pay, and download through MapWarehouse's online store. Details.

  • 5. Can I preview the imagery to ensure there is no snow or cloud cover?
     

    Thick cloud cover expressed as a percent of the photo's coverage area is available from DigitalGlobe for archived imagery. Seasonal snowpack coverage can be seen clearly in the preview, the probability of trace amounts of snow on the ground that aren't obvious in the preview will be estimated by cross-referencing the image date and location against historical weather data. Our customer service team will preview the archived imagery available for your area of interest and choose the best options for you to select from.

    For imagery captured on demand, imagery with snow cover can be rejected in regions where permanent snow packs are not typical if specified in advance, subject to seasonal norms. Customers must accept imagery containing cloud cover of 15% or less, with pricing options to accept only imagery meeting more stringent conditions.

  • 6. How does the quality of satellite imagery compare with orthophoto?
     

    Each sensor vehicle is different. In general, the level of detail seen in the image and geolocational accuracy will be better for orthophoto flown from aircraft. Satellite imagery is superior in that new imagery can be collected and delivered on much shorter notice anywhere in the world, and includes more spectral bands outside the visible range.

  • 7. How long does it take to receive my imagery?
     

    For archived imagery, once you approve your quote, delivery of your imagery generally takes less than a week. To order tasking for new imagery, you can select the preferred time frame for collection, but delays may occur because of unfavourable ground conditions at the site. For very large sites, it may take more than one pass for the sensor to complete the collection, which could occur days or weeks apart. Once the new imagery is collected, delivery will be within a week.

  • 12. Is there anything newer?
     

    We update large portions of our aerial imagery every year to keep up with demand for new data, especially in suburban areas where land development is taking place. In the built environment, the imagery will be different every single year, so it's worth the effort to fly the same areas over and over.

    The same is true for many types of "cultural" features such property line boundaries. Not every parcel changes every year, but within our large database covering all of Ontario, enough parcels change to need scheduled updates to maintain the relevance of the information a few times a year.

    Not so, however, with other types of mapping. One of our most popular data products is elevation mapping which was produced in 2002. Since our DEM and contour mapping is looking at bare earth topography, and the lay of the land doesn't generally change, there's no reason to update the data based solely on its age.

    There are a few exceptions. Activities that change the landscape such as mining, dam building, and urban expansion would require an updated map if those activities took place at your area of interest since the DEM was produced in 2002.

    Also called topographic relief mapping, contour mapping shows variability in the elevation, slope, and aspect of the terrain using isolines, lines connecting points of equal elevation.

  • 14. Coordinates System
     

    A reference system used to correlate locations on a map with real locations on the Earth's surface.  Coordinate systems are generally based on grids where locations are described based on distance from the origin of the grid.  Geographic coordinates, for example, are a spherical coordinate system expressed in latitude, longitude, and sometimes elevation, meaning degrees north from the equator, west from the prime meridian and distance above sea level, where the degrees are radial from the earth's centre.  Projected coordinate systems are based on a cartesian grid expressed in distance north and east from the origin of the grid cell, where the curved surface of the Earth has been conformally projected to flat plane.  Geographic coordinate systems work well for worldwide applications, projected coordinate systems, of which there are many, work best for local level applications.

  • 15. Crabbing
     

    When capturing aerial photo from fixed wing aircraft, crabbing is the adjustment of the flightline on the fly to compensate for wind in order to remain on the intended path and capture the intended targets.  The consequence of crabbing is that the orientation of the images will not be parallel with the intended flight line, which affects the amount of overlap and side lap between images, which can cause difficulties with creating stereo pairs.

  • 1. Datum
     

    Also called a geodetic datum, a datum is a reference system to describe the ellipsoid, or Earth-shaped model used to define the origin and orientation of a coordinate system.  The most common datums used in Canada to translate coordinates to correct locations on the Earth are WGS84 (World Geodetic System 1984, based on the WGS84 ellipsoid) for geographic coordinates, and NAD83 (North American Datum 1983, based on the GRS80 (Geodetic Reference System 1980) ellipsoid for projected coordinates.

Black represents a DN of 0, meaning all the energy was absorbed by the surface material, white represents a DN of 255, meaning all the energy was reflected by the surface material.  Graytone images represent of the variation in spectral reflectance values of the surface materials across a region.

  • 6. DSM
     

    Digital Surface Model. A topographic elevation model of the Earth's surface including every natural and artificial feature.  DSM forms the basis for creating true orthophoto production.

  • 7. DTM
     

    Digital Terrain Model. This type of surface uses break lines in addition to spot heights to refine the model.  The breaks are identified from our orthophoto and delineated along terrain impacting features such as ridges, valleys, watercourses, road edges and structures.  When the spot heights are interpolated to create the terrain model or contour lines, the terrain disruptions at the break lines are taken into account to produce a more true to life representation of the surface.

  • 17. ORM
     

    Oak Ridges Moraine.  A ridge of unconsolidated glacial material running parallel to the north shore of Lake Ontario, dividing the region into two watersheds, one draining south to Lake Ontario, one draining north to Lake Simcoe. The unique characteristics of the moraine's geology make this region ecologically sensitive, particularly as it affects groundwater quality.

  • 18. Orthophoto
     

    Aerial imagery taken from a camera positioned directly vertical relative to the ground, allowing the observer to see only the roofs of tall buildings, or, imagery which has been mathematically adjusted using photogrammetry techniques to achieve the same perspective.  Orthophoto are precisely orthogonal, or at a right angle to the camera.  The result is that the imagery is uniformly scaled and can be used to measure distances and angles in the same way as a planimetric map.

  • 1. Panchromatic
     

    in satellite imagery, one broad spectral band with all the colours of visible light combined into a single band, commonly referred to as grayscale or black and white imagery.  Texture and intensity of spectral reflectance is represented visually by tones of gray ranging from fully black to fully white.

  • 2. Pansharpen

  • 9. Positional Accuracy
     

    Assessment and quantification of the difference between the location of a feature's geometry in a model such as a map and the true location of that feature on the Earth, in both horizontal and vertical planes.  There are different ways to express the estimated difference such as RMSE and CE90.  The outcome of spatial analysis depends on the quality of the inputs.

    The estimated range of error is important to understand the limitations of what the data can validly be used to assess.

  • 12. Radial Perspective
     

    In an aerial photo, the apparent displacement of features on the ground radiating outwards from nadir. The effect of radial displacement causes features of similar height to appear taller than they actually are the father away from the image centre they are.

  • 13. Raster
     

    Data comprised of information stored in a grid, typically pixels in an image.

  • 14. Rectification
     

    In georeferencing, rectification is the second step, once the new data is basically in position. Rectification, also called warping or rubber sheeting, is the process of differentially skewing regions within an image to better align with known locations within the established coverage area.

  • 15. Registration
     

    In georeferencing, registration is the first step to shift, rotate and scale the new data to align with an existing dataset.  When registration is complete, the outer boundaries of the new data will be correctly positioned, delineating the total coverage area.

  • 16. Relief Displacement
     

    The effects of changes in elevation appear amplified in aerial imagery because of a combination of radial displacement, flight altitude, camera focal length, and topography.  Peaks will appear displaced away from nadir, depressions appear displaced inwards, towards nadir.  The effects of relief are minimized with distance from the subject, and are therefore negligible in satellite imagery.

  • 17. RF
     

    Representative Fraction.  RF can be as either a fraction (1/10,000) or as a ratio (1:10,000) to define the linear relationship between the dimensions of the map and the area on the ground it covers, regardless of the unit of measure.  For example, OBM map sheets are produced with RFs of 1:10,000, meaning for every 1 cm on the map, there are 10,000 cm (or 100 m) on the ground.

  • 18. Remote Sensing
     

    Any method which acquires information about the subject from a distance, most commonly referring to aerial or satellite image capture.

  • 19. Resolution
     

    In terms of aerial imagery, resolution refers to the radiometric clarity, the area on the ground covered by a single pixel in the image, usually expressed as a linear unit like 10cm, meaning a pixel is 10cm x 10cm square.

  • 20. RGB
     

    Red Green Blue.  These colours are the channels on most computer monitors that combine to produce natural colour images.

  • 21. RMSE
     

    Root Mean Squared Error.  A method to quantify the positional accuracy of spatial data that measures the difference between observed and predicted values.  When georeferencing imagery, RMSE is calculated with respect to ground control points.  Mathematically, it is the square root of the average of the square of all the error.  In practice, an RMSE of 0 is the target of no error, values less than 1 are desirable.  Since the calculation is based on the squared value, the output error value can inflate quickly as error increases.  Keeping the error low is important for the validity of predictions or models created from the data.

  • 1. Scale
     

    The linear relationship between the size of a model like a map and size of the real area it describes.  Scale is usually expressed as an RF (representative fraction) or by a scale bar which gives a graphical representation of the relationship, or both.  In general, large scale maps, such as 1:5,000 scale, show more detail and cover a smaller geographic area than small scale maps, such as 1:50,000, which cover large areas with less detail.

  • 2. Sensor Vehicle
     

    In satellite imagery, the sensor vehicle is the satellite carrying the camera equipment.

  • 3. SHP
     

    Shape or Shapefile.  SHP is a common vector file format used in GIS applications, particularly ESRI software.  A shapefile is made up of a handful of associated files with different extensions that record the geometry, tabular attributes, and spatial referencing information.

  • 4. Spectral Bands
     

    In aerial and satellite imagery, spectral bands are normally named by the section of the electromagnetic spectrum they describe, such as red, green, blue, NIR, IR, or panchromatic.  Each band is capturing a distinct wavelength range reflected from the surface material in the image. Each band can stand alone as a grayscale image, or can be viewed simultaneously with other bands, each assigned to display in one of the red, green, or blue colour channels on a computer monitor.

  • 5. Spectral Signature
     

    Spectral signature is a distinctive pattern of spectral reflectance by various materials, and can be used to identify and classify those materials based on comparison to known values.  In a similar way that an observer can identify objects in an aerial image qualitatively based on colour, the signature quantifies in a graph the reflectance quantity (intensity) vs wavelength (colour) to produce a curve which includes energy beyond the visible spectrum.

  • 6. Spot Height
     

    In digital elevation models, spot heights are used to record the precise elevation at a specific coordinate point, usually in a uniform grid or as close to a grid as possible depending on the limitations of the region's terrain and where the ground may be obscured, making accurate elevation measurements difficult.  Local high and low points in the terrain are typically recorded as well.  Spot heights are used to estimate the locations for contour lines of equal elevation.

  • 7. Stereo Pair
     

    In remote sensing, stereo pairs are two overlapping images taken from slightly different viewing angles, such as images captured in succession from a moving plane. Using a stereoscope (3D viewing glasses) the observer can view the imagery in 3D.  Stereo pairs are used to create elevation models and orthorectify aerial imagery.

  • 8. SWIR
     

    Short Wave Infrared.  Electromagnetic radiation with wavelengths roughly 1400-3000 nm, longer than both visible light and infrared energy.  SWIR energy can captured as images by sensors in the same way a photo is captured from natural light by a camera.  The WorldView-3 satellite launched in 2014 is the first commercial satellite with SWIR offerings.  The advantage SWIR offers over other bandwidths is capacity to penetrate haze and smoke, and for distinguishing between different types of minerals.

  • 9. Tasking
     

    When ordering commercial satellite imagery, tasking means ordering a new image capture for your site according to your specifications, as opposed to ordering from a catalogue of archived imagery.

  • 10. Teranet
     

    A partner company of FBS.  Teranet is a provider of parcel mapping.

  • 11. TIN
     

    Triangulated Irregular Network.  A means of representing a terrain using a series of points with x, y, and z coordinates connected by straight lines to form a tessellated 3-dimensional surface.  TINs can be created from DEMs to form a vector surface.  TINs offer an advantage because of smaller file sizes compared to raster based surface models, but may be less suited to slope and aspect analysis.

  • 12. Topo
     

    A topo is another name for a topographic map, such as Ontario Base Mapping.

  • 13. Topographic Relief
     

    The shape of the surface of the Earth, particularly the variability in elevation.  Topographic relief is often represented on a flat map by contour lines.
