| 摘 要： | 1:5万重点城市及经济开发区水工环综合空间数据是"数字国土"的重要组成部分.应用MAPGIS作为建立数据库的操作平台,通过对基础资料的矢量化,将所得的综合点、线文件进行编辑,误差校正后,分层形成图形文件,将图形文件与属性文件相联接,再通过投影转换和数据格式转换,形成水工环地质综合空间数据库,从而为今后的空间分析和多用途的开发应用提供了重要的基础数据资料.

| Abstract: | The synthetic space database of hydrology,engineering and environmental geology in 1: 50000 scale for key cities and economic developing zones is an important component part of the Digital Land Program.During the establishment of such a database for Dalian region,we take the MAPGIS system as the operating platform,by inputting the basic vector data,editing the graphic elements(dots,lines,ets.),correcting errors,constructing graphic layers and connecting the attribute to graphs,then converting projection and format,finally accomplish the synthetic space database.It provides an important basis for further spatial analysis and multi purpose development and application. |
