The Chittenden County Regional Planning Commission’s GIS office has provided map & Geographic Information System (GIS) services to CCRPC staff and the 19 towns in Chittenden County since 1989. We also work cooperatively with many state agencies and non-profit organizations in our region. Our work centers on projects in the fields of land use, transportation, natural resources, emergency preparedness, and community development. Projects include town plan mapping, zoning maps, thematic mapping of natural, cultural and transportation resources, and limited GIS software support. Mapping products can be paper, digital and/or online interactive maps.
