Hiking and Wilderness Trails for NextGen 911 (Hosted Feature Service)

Athough MassGIS has served trails information from the Department of Conservation and Recreation (DCR) for many years, this new Trails layer is MassGIS’ first attempt at a statewide, multi-sourced dataset. This layer was created from two primary sources, DCR Trails and the Metropolitan Area Planning Council’s (MAPC) Trailmap. Additionally, a few other trail networks were added from OpenStreetMap (OSM), municipalities, and conservation organizations, but the amount of information from these sources is relatively small. This trails dataset was created for use in the State 9-1-1 Department’s mapping application Response Assist and is intended to assist telecommunicators with lost hikers as well as potentially responding to emergencies within remote areas. Because the layer is primarily being used by 9-1-1, it was decided to focus on those trails found in wilderness areas and used as hiking trails. This resulted in the omission of many arcs from the source data. Examples of these include cart paths on golf courses, the network of paved paths on school campuses, sidewalks, and many other arcs that could functionally serve as trails but were in relatively open and developed areas. Updated with linework from OpenStreetMap in summer 2023 and published on November 14, 2023.
