Compilation base maps covering the entire coast and islands were plotted at 1:5,000 using 1:5,000 Color Ortho Imagery and 1:24,000 USGS Topographic maps, all modified and enhanced by MassGIS. In addition, town boundaries, the territorial waters line and roads were plotted on these base maps. Shellfish project biologists compiled area boundaries onto the base maps, and these boundaries were then digitized or constructed using existing hydrography, town or territorial sea lines by DMF GIS personnel. Check plots were created and boundaries QA/QC'd by the biologists. Separate 11 x 17 color plots are produced for each growing area based on the map extent of the area and its sampling stations. Classification area lines which need to be added, moved or deleted are compiled on these plots and automated by DMF GIS staff. A new 11 x 17 is produced and kept on file until another area change occurs. 8BB96381-E80E-4C9D-A7A4-4C4DB22423A3
