This paper studies the methods of large-scale CAD-based data acquiring, data transforming between CAD data and GIS data, date updating in database. A file format called SIF (Spatial Information format) is designed for transforming data format, which is represented by XML. Based on the arithmetic for addition acquiring and addition updating, a large-scale data transferring and updating system is developed with ArcEngine fund on the project of Hi-tech Zone Infrastructure GIS (HiGIS) in ChangZhou, and there are 308 blocks of 1:2000 maps in ChangZhou have been done experiment on transferring and updating, which realizes the spatial data sharing between CAD and GIS.
