Based on GDAL (Geospatial Data Abstraction Library), sharing of lunar spatial data from different sources has been achieved which makes up the shortage of traditional spatial data processing software. According to the characteristics of the lunar spatial data, three types of lunar spatial data conversion services, including desktop, network and network processing services (WPS) are designed and implemented using spatial data exchange model, effectively solving the PDS (Planetary Data System) and other lunar spatial data's sharing problems. In the practical application, the program has achieved good results. The next step, parallel technology will be studied to improve the efficiency of data conversion.
