Research on CAD Data Format Conversion for Transport Infrastructure Information

This brief introduction to the needs of the project background, the need for format conversion and conversion work-related theories. By comparing the current format has several ways of combining the actual situation of the project was based on Arcmap format conversion studies, and the converted coordinate system conversion, the registration layer, the topology of layers are discussed. Experimental results show that the format conversion, graphics conversion and the geometric consistency problem is a good solution, the data described in this article work for GIS applications and communications infrastructure to provide a reference for information research.
