Abstract: | Based on the developing tendency of present China's basic GIS, this paper discusses the designing idea for scales of 1∶10 000, 1∶50 000, 1∶250 000 and 1∶1 000 000 pyramidlike multi-layer and multi-resolution of the basic GIS. A technical line for the construction of basic GIS of the whole country and various provinces for sustainable development is put forward. And some important theoretical GIS issues touched by the technical process are discussed. |
