摘要: 地理信息系统的广泛应用使地学数据的使用大为扩展,但关于地学数据的一些基本认识,如地学数据概念、地学数据的基本特征等并没有达成共识。在分析地学数据概念和来源的基础上,对地学数据的基本特征,如多尺度特征、分布式特征、空间拓扑特征等进行了详细的说明。

Abstract: More and more geospatial data have been used, but some basic concepts of geospatial data such as geospatial data, basic characteristics, are still have not consistent definitions. Based on those problems, the paper describes the sources, definition of geospatial data, and mainly describes the basic characteristics of geospatial data such as multi spatial scale, multi temporal scale, distributed characteristics and topographical relationship.
