An interesting feature from Amerisurv looks at the topic of CAD-GIS integration
Surveyors have been using Computer Aided Drafting/Design (CAD) for decades to draft surveys and to do design. As society becomes more spatially conscious, the ability to integrate data with geographic information systems data increases and is now to the point where CAD-GIS integration is expected by clients and necessary as part of the analysis and design of many survey projects.
With the appropriate GIS software, one may directly view CAD files and CAD features in a GIS environment in order to display a visual representation of the CAD elements in context with GIS data. Alternatively, one can display GIS data in CAD software. However, in order to empower the CAD data for GIS spatial analysis, the CAD features should be converted to a GIS format that have feature attributes assigned to them. This article explains the simple steps necessary to convert CAD data to GIS format.
