Application Summary AI generated
This standard specifies the technical requirements, content, and representation methods for producing national fundamental scale orthophoto maps at 1:250,000, 1:500,000, and 1:1,000,000 scales. It is applied in surveying, mapping, and geographic information systems (GIS) for national land planning, resource management, and large-area spatial data analysis. The standard ensures consistency and accuracy in orthophoto map production for government agencies and engineering projects requiring medium-to-small scale geographic reference.
