Abstract:
The data presented here are taken directly from the Mass GIS orthophoto wetlands datalayer, projected into UTM zone 19, NAD 83 meters. They show wetlands in the area surrounding the Boston Harbor Islands.
Purpose:
The purpose of this data set is to provide reference material to assist in the management of the Boston Harbor Islands National Recreation Area.

Process_Step:
Process_Description:
The wetlands were interpreted from stereo, 1:12000 scale, color-infrared by staff at UMASS Amherst. The interpretation is field checked by Department of Environmental Protection (DEP) Wetlands Conservancy Program (WCP). Completed interpretations are then scanned. The resulting images are converted to ARC/INFO coverages. The distortion from terrain and camera coordinates are removed using a photogrammetry software program, and a digital terrain model (DTM) derived from 1:5,000 black and white ortho-rectified aerial photography. The corrected coverages are then mapjoined and clipped by the boundary of a State Plane Coordinate grid cell which represents a 4 kilometer by 4 kilometer orthophoto sheet. Plots are generated at 1:5000 scale and final quality control is performed at that scale. It should be noted that the resulting wetlands are for planning purposes only; final wetland boundary determination must accord with MA Act M.G.L. c. 131. The datalayer is currently under development. Data production is complete in the Wachusett, Ware and Quabbin basins. Fort Devens, Fort Devens Annex and Cape Cod, part of the North Shore as well as part of the Metro Boston area are also complete. Production of additional wetland data is underway in the North Shore area.
