Abstract: GIS cognition depends on people's understanding and cognition to map. GIS data organization, whose contents come from the real world, is one of the key and core problems on GIS. So, it is necessary to Abstact and describe the real world in order to make the real world expressed on the computer and to develop the practicable GIS. Certainly, geographic spatial cognition should be applied to the whole Abstact course. Consequently, we must reasonably organize the data on computer based on the cognitive theory during developing GIS.
