Abstract

CAD data created for drawings and Geographic Information System (GIS) data are created for different purposes. As a result the software's data models are inherently different, and the files differ in their structure and attributes. CAD data contain information to draw it with features organized by mixed layers. While GIS data has an additional functionality, its feature can hold huge amounts of data describing the features. Moreover, GIS data is “spatially informed” regarding adjacency and other spatial relationships. Thus, the conversion of CAD files to GIS shape file may face problems and data may get corrupted.
