Observations about Adding Ancient Roads to the VTrans Road Centerline Data Layer


S.E. Moulton, Mapping Unit, Vermont Agency of Transportation (VTrans) Montpelier, Vermont ‐‐ June 2010

In response to Act 178 of 2006 (Unidentified Corridors)1, the VTrans Mapping Unit was presented with the challenge of mapping the additions of Class 4 town highways and legal trails using information provided from towns and any ancillary data that was available. In most cases, a rudimentary sketch map accompanied the volumes of deeds, surveys, old maps, and other documents from the towns, providing a general idea of where to add the highway or trail. A sophisticated suite of tools was employed to make the town highway map update possible, leveraging imagery, geo‐referencing old maps, and running traverses using COGO tools.
