规范化空间对象模型与实现技术

随着人们对空间信息科学的理解和ＧＩＳ应用的广泛深入，人们对地理空间的抽象对象及相互关系有了趋于一致的认识。为了在不同的系统之间，实现空间数据共享，许多国家及有关的行业，制定了各自的空间数据交换标准，实际上规范人们对空间对象及相互关系的认识。

FORMAL SPATIAL OBJECT MODEL AND ITS IMPLEMENTATION

In order to share spatial data,many countries and departments have drawn out spatial data transfer standards or spatial data exchange formats.This paper introduces several spatial data structure and standards,analyzes the concept objects,logical objects,logical structures,and data formats of GIS and proposes the Formal Spatial Object Model (FSOM).The author of the paper thinks that the FSOM should be instead of the spatial data transfer standard for spatial data sharing.
