Monomoy National Wildlife Refuge Boundary Data for GIS

U.S. Fish and Wildlife Service Region 5 provides boundary layers for the Monomoy National Wildlife Refuge in Massachusetts. Data was digitized from status maps and orthophotos at a scale of 1:24,000, with a major recompilation completed on May 25, 2000. The dataset serves as a spatial reference for refuge boundaries within GIS applications.

Use Cases

• Overlaying refuge boundary polygons with other GIS layers for habitat analysis or land-use planning.
• Using the coded 'status' attribute on polygons to analyze land ownership patterns within the refuge system.
• Applying the coded 'boundary' attribute on arcs to differentiate between types of boundary lines, such as mean high water lines or congressionally approved limits.
• Integrating the 1:24,000 scale boundary data as a base layer for regional environmental impact assessments.

Strengths

• Data compiled at a standardized cartographic scale of 1:24,000.
• Underwent three levels of quality-control review for spatial and thematic accuracy.

Limitations

• Boundary data is based on a recompilation from 2000, using orthophotos from 1994, making it temporally stale.
• Specific row counts, column details, and total spatial extent are not provided in the description.
