摘要
介绍了地理信息系统(GIS)的基本概念和发展现状,针对目前地理信息系统中存在的多种空间数据格式问题,结合实际数据,初步实现了几种数据格式之间的相互转换,同时基本解决了在格式转换过程中出现的数据错误问题。并结合WebGIS这一当今GIS发展的新方向,利用AutodeskMapGuide和ASP初步实现了数据的发布以及属性查询分析。
The basic conception and development status quo of GIS is introduced; in allusion to the problem of multi-spatial data formats that consist in GIS in transforming, the transformation among several data formats is realized primarily based on actual data; and meanwhile data error problem in transforming is solved. Combined with WebGIS' new developing direction, the data issuance and attribute query analysis are realized by means of Autodesk MapGuide and ASP.
