基于CNSDTF的国家基础地理数据共享研究

Realization of National Fundamental Geographic Data Sharing Based on CDSDTF

针对多比例尺国家基础地理矢量数据的特点,分析了最新发布的《地理空间数据交换格式》国家标准应用于国家基础地理信息共享的可行性。结合国家、省、市基础地理数据交换的需求,设计和开发了地理信息数据格式转换软件(GIFT),并在国家基础地理信息中心进行了测试与验证。

According to the characteristics of multi-scale national fundamental geographic vector data,the feasibility of application of the latest Spatial Data Transfer Format （SDTF） standard to national fundamental geographic data sharing was studied. The result showed that SDTF can be completely used for national, provincial and city data exchange. Then we designed the Geographic Information Format Translator （GIFT） software to facilitate the transformation of geographic data. GIFT had been applied in National Geomatics Centre of China （NGCC） and had been proved to be practical.
