The Methods of Small Scale Aerial Photo Manufacture Digital Orthophoto Map

Using 1:50000-1:60000 aerial photos to make 1:10000 orthophotos is in a phase of experiment.This paper discusses the implementation plan of guaranteed orthophotos projection precision in the experiment,such as DEM data acquisition and images mosaic,uniform color of the key technologies implemented.Furthermore,it probes into the key technology to make 1:10000 orthophotos projection by using 1:50000-1:60000 aerial photos,and then puts forward solutions.
