This paper describes and demonstrates how to generate high-precision digital orthophoto maps by the low altitude photogrammetry. Meanwhile,it also emphasises on the technical route of generating high-precision digital orthophoto maps and gives the precision analysis of the orthophoto map obtained.Moreover,the paper considers the detail factors of generating high-precision digital orthophoto maps.Finally,experiments on digital orthophoto map generated by the low altitude photogrammetry have shown that the accuracy has reached 1∶ 500 map standards.
