摘要随着地理信息系统在各行业领域中应用的不断深入,多源异构空间数据的共享成为一种必然要求。分析了空间信息网格(Spatial Information Grid,SIG)环境中空间数据应用的现状,在此基础上对SIG环境中空间数据共享代理的研究与设计进行深入探讨,提出了一种实用高效的用于共享非OpenGIS标准异构空间数据的解决方案。 With the development of the application of Geographic Information Systems in each step of life, the sharing of multi - source and heterogeneous spatial data becomes a necessary need. First we analyze the applied status quo of spatial data in Spatial Information Grid （SIG） ,then deeply discusse the study and design of spatial data sharing proxy in SIG and introduce an effective and efficient solution for the sharing of non OpenGIS--standard heterogeneous spatial data.
