Application Summary AI generated
This standard specifies the technical requirements and procedures for producing digital topographic maps at scales of 1:25,000, 1:50,000, and 1:100,000 using aerial photogrammetry. It is applied in national surveying and mapping projects, land resource management, and infrastructure planning where accurate digital elevation models and vector data are derived from aerial imagery. The standard ensures consistency in data accuracy, feature classification, and map output for medium-scale topographic mapping.
