Abstract:

The lunar digital geological mapping is based on the data, which includes the Chang’E-1 (CE-1) CCD3C image data, interference imaging spectrometer(IIM) data, laser altimeter (LAM) data, Chang’E-2 (CE-2) CCD3C image data as well as other lunar geological data to study the material compositions of the lunar surface, structures elements and the information of geochronology, to compile the lunar geological map and to establish spatial database of the moon by using the ArcGIS platform and Geodatabase model. In this paper,taking the Arctic region as an example, we have made the standard, process, method and legend for the lunar geological mapping, preliminarily complied the geological map of the Lunar Arctic Region(YQ-1) at a scale of 1∶2.5M and established the spatial database, which have laid the foundation for the geological comprehensive study of the moon, the geological mapping of the global moon, and also the geological mapping of other celestial bodies in the future.

Key words: digital geological mapping, ArcGIS, Geodatabase, lunar Arctic region
