What Is An Orthomosaic Map? (Answered in under 100 words)
The Answer:
An Orthomosaic Map is an aerial photograph comprised of dozens, hundreds, or thousands of smaller overlapping images, typically captured with a drone or UAV. These images are “stitched together” with specialized photogrammetry software resulting in an Orthomosaic Image that has been “orthorectified” or geometrically corrected to provide uniform scale throughout allowing for accurate measurement of distance.
Orthophotos, as they’re also called, are similar to what you’d see in Google Maps but with much higher detail and accuracy, allowing users to zoom in and out without distortion, providing numerous uses for Agriculture, Construction, Real Estate, Emergency Services, and more.

*Notice in the above orthomosaic, that no matter what part of the image you’re looking at—it appears that the camera is pointing straight down. This image is comprised of almost 300 individual photographs (all taken straight down or nadir).
