OUTLINE (25k coast): Shapefile |
- OUTLINE_POLY and OUTLINE_ARC - contains the state outline with a 1:100,000 coastline
- OUTLINE25K_POLY and OUTLINE25K_ARC- contains the state outline with a 1:25,000 coastline
Production
For the both layers, MassGIS digitized 1:25,000 linework from U.S. Geological Survey mylar map sheets for land boundaries. For the OUTLINE layer, a 1:100,000 coastline was extracted from USGS Digital Line Graphs. For OUTLINE25K, the coastline from the 1:25,000 Hydrography layer was used. All processing was done in ARC/INFO.Attributes
