This paper discusses the rapid production of orthophoto in the situation of flight pattern of aero geophysical exploration. The Thiessen polygon method is used to build sampling area and automatically generate orthophoto of the measured area, with no need to carry out manual edge processing. Considering the characteristics of inmagnanimous images with large quantities of data, the authors propose a method characterized by demonstration, roam, and zoom of magnanimous image based on pyramid memory scheduling strategy of piecemeal and graduation.
