Abstract
The Moon is a special extraterrestrial body, without atmosphere, flowing water, even creatures. So the surface characteristics, such as the texture, the terrain and the color, are unchanged permanently. The images obtained by telescopes , orbiters, even rovers are insistent, and there is not apparent difference in color and texture. Unlike the image, the lunar topographic color coded maps released by USA, Russia, ESA, Japan, China and India are not all unified, which would make a obstacle to understand the topographic information. This research suggest a standard (scale, subdivision, coding, color, media and so on) and a method to present the lunar surface in a uniform style. Chinese cartographers have set up the national standards(lunar spatial coordinate system, Subdivision and numbering for the lunar primary scale topographic maps, which are the foundational standards for lunar mapping ) to produce topographic map at1:10 000~ 2 500 000. The experience and map product shows the unified standard and method is suitable for presentation of paper map, globe, electronic and 3D map.
