The mission of Andover's Geographic Information System (GIS) program is to provide town-wide spatial information for mapping and analyzing data about our community.
Andover's GIS Program
Initiated in 1998, GIS data captured from aerial photography included "planimetric" layers such as building footprints, roads, topography, water bodies, sidewalks, recreation features, and paved areas. Additional features were derived from GPS field collection (water, sewer, and drainage utilities) or by merging GIS data with digitized maps (parcels and wetlands mapping). Other GIS layers were added for regulatory or informational purposes, including zoning, overlay districts, school districts, voting precincts, open space, snowplow routes, and public safety routes. Data maintenance by Town staff is an on-going process, using a variety of sources including digital imagery from MassGIS and Pictometry, GPS field collection, and survey plans.
