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.
