The MassDEP Wetlands datalayer comprises two feature types, polygons and arcs (lines). The attribute codes in the polygon layer describe different types of wetland environments and the arc attributes describe line types based on adjacent polygon types or arcs defined as hydrologic connections.In this service the wetland areas are displayed using outlines and labeled with wetland code abbreviation. This symbology is useful for displaying the data atop aerial imagery.Please see https://www.mass.gov/info-details/massgis-data-massdep-wetlands-2005 for more details.

The MassDEP Wetlands service comprises two feature types, polygons (areas) and arcs (lines). The attribute codes in the polygon layer describe different types of wetland environments and the arc attributes describe line types based on adjacent polygon types or arcs defined as hydrologic connections.This map service displays the data based on the generalized categories in the POLY_CODE and ARC_CODE fields.The 2005 MassDEP Wetlands layers provide a medium-scale representation of wetland areas of the state. Wetland areas consist of open water, vegetated wetlands, and coastal landforms. The hydrologic connection arcs provide a medium scale representation of linear features (less than 50 feet wide) that appear to contain flowing water (either intermittently or perennially) and flow into, out of, or between mapped wetland polygons. Hydrologic connections may consist of rivers, streams, ditches, culverts, swales, or other water conveyance features.Please see MassGIS' metadata for more details.A map service is also available.
