Summary

This data depicts geographic features on the surface of the earth.

To be used for planning purposes only.

Description

Orthoimagery is remotely sensed image data in which displacement of features in the image caused by terrain relief and sensor orientation have been mathematically removed. Orthoimagery combines the image characteristics of a photograph with the geometric qualities of a map.

This orthoimagery consists of 1-foot pixel resolution, natural color county mosaics in MrSID MG4 format derived from downsampled Nearmap imagery acquired in the late winter/early spring of 2025.
