Based on the National Platform for Common Geospatial Information Services, the Yunnan Digital Country Project and the Mapinfo Public Data as data sources, the Kunming Fine Geographic Information System (GIS) is developed independently as fined as a town, highway, administrative village and natural village under the C# development environment, which solves the problem of lacking the fined GIS data in the baselevel meteorological services. This paper introduces the parsing and mapping processes of the standardformat base data and precautions, and realizes the operational application of the standardformat base data of weather radar in the baselevel meteorological service in China. During the operational application, it is founded that the echo intensity of the standardformat early base data from CC weather radar is seriously weakened; the fusion application of the Kunming Fined GIS and Kunming weather radar echo images can accurately locate the strong radar echo area, which can guide the refined meteorological service, and improve the capability of fine weather warning, shortterm and nearrefined forecasting and nowcasting and disaster prevention and mitigation.
