Overview

This layer stores the status of the Surficial Geology (1:24,000) data development project. Tiles, named "A" through "J", comprise U.S. Geological Survey 7.5-minute topographic quadrangle sheets and represent the units by which USGS develops and distributes the data.

The layer is named SURFGEO24KSTATUS_POLY.

See the Surficial Geology (1:24,000) Status Map

Production

A polygon layer was created by coding the Quadrangle Template and dissolving it by tile name ("A" through "J").

Attributes

The layer's polygon attribute table has the following fields:

Field Name	Description
SG_AREA	Tile name, "A" through "J"
SG_AVAIL	Availability of 1:24,000 surficial geology data for this tile. "Y" for yes, "N" for no

Maintenance

MassGIS maintains this layer and will update the SG_AVAIL field as new geology data become available from the USGS. The most recent update was for the addition of Area "I" in August 2015.
