How often is data updated in MapWarehouse?

Viewed 445 Times 0 Comments

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.
