GB/T 7931-2008 Specifications for aerophotogrammetric field work of 1∶500 1∶1 000 1∶2 000 topographic maps
Abstract
This standard specifies the basic requirements for field operations in mapping 1:500, 1:1,000, and 1:2,000 topographic maps using analog and analytical aerial photogrammetry methods. This standard applies to the field production of aerial photogrammetry topographic maps at scales of 1:500, 1:1,000, and 1:2,000.
