LandAir has completed over 50 databases working for the Georgia Department of Transportation, ranging from intersections to projects 20 miles in length. We use CAiCE to produce a 3D database, and MicroStation to accompany the database, to produce the standard CAD drawings with labels. All these projects have followed the Georgia Department of Transportation’s strict guidelines for levels, line weights, line styles, and symbols specified by the Electronic Data Guidelines.
