Abstract: | Aerophotographic survey is frequently used in large survey projects.Data produced from aerophotographic survey is charac-teristic of large quantity, authenticity and explicitness.Aerial triangulation is an important procedure in aerophotographic survey.This paper compares the precision analysis derived from two automatic aerial triangulation softwares, Geolord-AT and PixelGrid-AT. Two softwares are applied to the same area.Precision analysis is conducted after the elimination of gross errors and adjustment. |
