Abstract

Central Employment Area. The dataset is a polygon representing the location and attributes of Central Employment Area (CEA) (the CEA is the core area of the District of Columbia where the greatest concentration of employment in the city and region is encouraged), created as part of the DC Geographic Information System (DC GIS) for the D.C. Office of the Chief Technology Officer (OCTO) and participating D.C. government agencies.

Jurisdictions were identified from public records (map and written description created by the National Capital Planning Commission) and heads-up digitized from the 1995 orthophotographs.

All DC GIS data is stored and exported in Maryland State Plane coordinates NAD 83 meters.

METADATA CONTENT IS IN PROCESS OF VALIDATION AND SUBJECT TO CHANGE.

Purpose

This data is used for the planning and management of Washington, D.C. by local government agencies.

Use constraints

Jurisdictions were identified from public records (map and written description created by the National Capital Planning Commission) and heads-up digitized from the 1995 orthophotographs. The resulting shapefile was then recreated as a coverage using the appropriate planimetric features (street centerlines, etc.) and the polygon built.

A base ArcInfo coverage of correct line work (snapbase.e00) for all DC data was developed after the final delivery of the planimetric street centerlines. The datasets were selected from the snapbase coverage, creating coincident geography with the other DC GIS datasets. When imported into the DC GIS geodatabase the coverages shift 0.01mm since the geodatabase supports only 11 digits of precision, not double precision (16 digits).

Planimetrics were created at a scale of 1:1,000. This means that a well defined feature falls within two feet of true position.

All DC GIS data is stored and exported in Maryland State Plane coordinates NAD 83 meters.
