Description
Orthophotos are an aerial photo dataset covering Estonia.
An orthophoto is a processed aerial photo from which distortions caused by terrain relief, camera tilt relative to the ground at the moment of exposure and camera central projection are removed. A digital orthophoto has a certain pixel size or resolution which shows the smallest indivisible exposed area on the ground (Ground Sampling Distance, GSD).
Orthophotos have a nationwide coverage and correspond to the scale of 1:5000-1:10000 (pixel size 20-40 cm). Orthophotos for densely-populated areas are produced with the pixel size of 10-16 cm.
The mono_low_flying dataset has a single grayscale band for densely-populated areas.
