What kind of a map is an aerial map?
there is no such thing as an aerial map however there are aerial
photographs. This are normally obtained by mounting a special
camera onto a plane and the plane flies over the region you wish to
obtain photos from. The photos then undergo a process known as
georefrencing where actual points on the ground are matched with
actual points on the photos in order t give co-ordinates to the
aerial photograph. different photograph may be combined to map a
larger area
