An Office of Traffic Data recently approached us to help them solve a long running problem. They want to gather design project information to maintain up to date feature records in their GIS system. We knew that the answer was in the CAD drawings and, to some degree in ProjectWise. We decided to start with a test case – attempt to identify lane centerlines, edge of pavement, and shoulder widths.
There are several questions:
- What coordinate system is used?
- Are the files geographically accurate?
- How do we project CAD Cartesian to Lat/Long to get GPS coordinates?
- How do we identify start and end points of shoulders, medians, turn lanes, and other linear features?
While this is a work in progress, CLIP shows a lot of potential. Automatically mining data from projects that typically get archived and stay dormant, unleashes value until recently hidden from most organizations.
