This CT Full State layer consists of two individual polygons representing the land and Long Island Sound borders that make up the state of Connecticut. This land portion of this feature layer is directly derived from the CTDOT Municipalities feature layer geometry, created by CT Department of Transportation. The full state is created by dissolving all the municipalities into one polygon. The Long Island Sound portion is derived from points defining the Connecticut state waters boundary line, as described in the CTDEEP Marine Fisheries Information Circular (Table 6). This feature layer includes US Census Federal Information Processing Standards (FIPS) codes that are associated with the state of Connecticut.  Field name Field description StateFIPS US Census FIPS code associated with the state. Type Describing if the polygon includes the “land” portion of the state or the “Long Island Sound” portion. ObjectID Unique Object ID.
