The Research for Coding of CAD Planning Data Input
As the front - end data source of city fundamental geographic information system platform, CAD planning data only can be used by fundamental geographic information systems after CAD to GIS data format conversion, which always results in data losing. Basing on the characteristics of CAD planning data, this paper developed a set of effective geographical coding schemes to realize nondestructive CAD planning data input as a solution for this problem.
