我国地球空间数据框架的设计思想、技术路线及若干理论问题讨论

Design Thinking,Technical Route and Some Theoretical Issues on the Geospatial Digital Framework

    摘要
  • 摘要: 根据当前我国基础地理信息系统的发展趋势,讨论了1:1万、1:5万、1:25万及1:100万金字塔多层、多分辨率基础地理信息系统的设计思路,即基于数字影像、数字栅格地图(DRG)和DEM及若干层数字线划图的矢、栅集成(2维或3维)框架结构系统;提出了建设可持续发展的全国及各省级基础地理信息系统技术路线;讨论了这一技术流程中涉及的重要的GIS理论问题。

     

    Abstract: This paper discusses in comparative detail the designing idea for scales of 1:10 000,1:50 000,1:250 000 and 1:1000 000 pyramid-like multi-layer and multi-resolution of the basic GIS,that is,the framework structural system based on the digital image,digital raster graph(DRG),DEM and vector and raster integration(2D or 3D) of several layer digital line maps.A technical line for the construction of basic GIS for the whole nation and various provinces for sustainable development is put forward.And some important GIS theoretical issues are discussed.
