Lunar digital elevation model data specification

1 Scope

This standard specifies the use of lunar lunar exploration to obtain the optical three-dimensional image data produced by the moon digital elevation model of image data quality, photo Shadow measurement processing, specifications, accuracy and product content. This standard applies to 1. 250000, 1. 1000000, 1. 500000, 1. 250000, 1. 100000, 1. 1.25000 and 1. 10000 and other eight kinds of scale moon digital elevation model production. Other scales lunar digital elevation model production can refer to the implementation of this standard.
