Application Summary AI generated
This standard specifies the technical requirements, content, and representation methods for producing 1:500, 1:1,000, and 1:2,000 scale orthophoto maps, which are geometrically corrected aerial or satellite images. It is applied in China for urban planning, land surveying, cadastral mapping, and infrastructure engineering projects where high-precision, large-scale base maps are required for detailed spatial analysis and design.
