Massachusetts Bay

This library contains GIS layers covering western Massachusetts Bay Quadrangles 1-3 and for Massachusetts Bay. The table below contains a short descriptive name of the GIS layers associated with Massachusetts Bay and combined Quadrangled 1-3, the file name of the layer, and the type of GIS file (shapefile, image, or grid). Note that the descriptive name is a shorter version of the full name found in the metadata. Click on View Metadata to view a description of the data or on the thumbnail under Download Zipped File to obtain a zipped file of the data.

To view these layers using ArcMap, open the usgs_multi_mbay.mxd file in the massbay_gis directory using ArcMap 9.1 and select the Massachusetts Bay data frame.
