Overview
The state barrier beach data layer was compiled by the Resource Mapping Project staff at the University of Massachusetts, Amherst for the Massachusetts Coastal Zone Management Program. The ArcSDE layer is named BARRIERB_POLY.
Production
A polygon coverage was built by digitizing interpreted feature boundaries not including the shoreline. The shoreline used in this coverage is from the 1:25,000 paper USGS Topographic Maps.
Attributes
The layer's polygon attribute table has the following items:
Item Name | Wdth | Oput | Type | Comments |
---|---|---|---|---|
BBPOLYID | 4 | 5 | B | Arbitrary numeric code to identity unique features. |
BBNAME | 8 | 8 | C | State designated alpha-numeric code for each barrier beach unit. |
Maintenance
