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

    Graphical Abstract
    • 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.
