Auto Coding Based on Division Alteration

By analyzing current status and implementation requirements of auto coding technology in GIS and data sharing, this paper points out that there are two urgent requirements needs for GIS and data sharing .One is research of auto coding technology and the other is dynamic coding technology. By the analyses above, this paper raises a model of auto coding system based on alteration of division, and auto coding of point elements are given as an example of system realization. Finally, three core functions in the system are explained in detail which are rules customization、code creation、code update.
