Abstract
The digitized software based on Auto Cad is one of the important ways that the GIS data are gathered, but because CAD software itself is not GIS software, while the data gathered are transfering the GIS system, a little data and information is lost. This paper realizes data gathering based on GIS by using data management means and characteristics of XDATA、HANDLE and GROUP of CAD itself, at the same time ,it gives consideration to convenient collection of the data and integrality of GIS data required.
