This is a Vector data set. It contains the following vector data types (SDTS terminology):
Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.000000. Longitudes are given to the nearest 0.000000. Latitude and longitude values are specified in Decimal degrees.
The horizontal datum used is North American Datum of 1983.
The ellipsoid used is Geodetic Reference System 80.
The semi-major axis of the ellipsoid used is 6378137.000000.
The flattening of the ellipsoid used is 1/298.257222.
Sequential unique whole numbers that are automatically generated.
Coordinates defining the features.

| borough | In Connecticut, New Jersey, and Pennsylvania, an incorporated place. |
| CDP | Census designated place - A statistical entity, defined for each decennial census according to Census Bureau guidelines, comprising a densely settled concentration of population that is not within an incorporated place, but is locally identified by a name. |
| city | An incorporated place in 49 States and the District of Columbia. In 20 States, some or all cities are not part of any minor civil division, and the Census Bureau also treats these as county subdivisions, statistically equivalent to minor civil divisions. |
| city (consolidated, balance) | The portion of the consolidated city minus the incorporated places. For statistical purposes, these entities are treated as statistically equivalent to a place and have no legal basis or functions. |
| city and borough | unknown |
| city and county | unknown |
| municipality | unknown |
| town | An incorporated place in 30 States. In New Jersey, Pennsylvania, and South Dakota, the Census Bureau treats these towns as the equivalent of a minor civil division. |
| village | An incorporated place in 20 States. The Census Bureau treats all villages in New Jersey, South Dakota, and Wisconsin, and some villages in Ohio as county subdivisions. |

The geospatial part of this data set was calculated from latitude/longitude coordinates from the U.S. Bureau of the Census 2000 Summary File 1 (SF1). The horizontal positional accuracy is unknown.
After processing, the data set is checked for drawing display and number of records and file sizes compared with source materials. This is a subset of the original dataset and has been clipped to the extent of the Long Island Sound GIS project extent.
No duplicate features are present.
