These base maps provide a platform for the wetlands data, which brings location data to life by making it easier to visualize, understand, and analyze. The detailed imagery used in the Wetlands Mapper application is provided by ESRI and originates from a variety of sources at various scales.
Wetland maps usually indicate wetland type (and in some instances other characteristics) as well as wetland boundaries. Maps are often prepared by simultaneous use of air photos or satellite imagery, soils information, topographic maps, flood and surface water maps and other types of information.
Wetlands are sometimes delineated by use of aerial photography, satellite imaging, maps, or modeling, as an alternative to collecting field data.
By integrating digital wetlands data with other resource information, the wetlands mapper is designed to deliver easy-to-use, map-like views of America’s wetland resources. The wetlands displayed on the Wetlands Mapper show wetland type and extent using a biological definition of a wetland.
The Wetland and Wetland Change Areas Map displays MassDEP photo-interpretted wetlands, areas of detected wetland change, Notice of Intent locations and Natural Heritage Endangered Species Program (NHESP) certified vernal pools.
