Massachusetts Technology Collaborative 50 meter elevation wind power density raster layer. The raster layer work was jointly funded by the Connecticut Clean Energy Fund, the Massachusetts Technological Collaborative, and Northeast Utilities System.
The raster data were re-classified (AWS_CLASS) in accordance with the 8 classes used by Mass. Tech et al. The data were then converted from raster to polygon using the GRIDPOLY command. The PWRDENSITY field was created to show the power density range (watts/sq. meters) for each class. The data were then transformed from WGS1984 to NAD83 SPC using NAD1983toWGS1984 transform 5 (United States) and clipped to the extent of the WINDSPEEDGRID_POLY layer created by MassGIS and AWS Truewind, LLC. Processing of this polygon layer was completed by the Massachusetts Water Resources Authority (MWRA) GIS program and provided to MassGIS for distribution.
The layer is named WINDPOWERGRID50_POLY.
The layer's polygon attribute table contains the following items:
AWS_CLASS Power density class (as defined by AWS Truewind) PWRDENSITY
Power density range, in Watts per square meters:
AWS Class Power density range (watts/sq meters) -1 <100 1 100-200 2 200-300 3 300-400 4 400-500 5 500-600 6 600-800 7 >800
The MWRA GIS program maintains this layer.
