Wards - 1990 (Ward90Ply)

Data format: SDE Feature Class

File or table name: DCGIS.Ward90Ply

Coordinate system: State Plane Coordinate System

Theme keywords: location, Government Jurisdictions, Wards, boundaries, Political Jurisdictions, boundaries

Abstract: Wards. The dataset contains polygons representing boundaries of District of Columbia 1990 election wards, 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. These political jurisdictions were identified from public records, including published maps and written legal descriptions and heads-up digitized from the 1995/1999 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.

FGDC and ESRI Metadata:

Metadata elements shown with blue text are defined in the Federal Geographic Data Committee's (FGDC) Content Standard for Digital Geospatial Metadata (CSDGM). Elements shown with green text are defined in the ESRI Profile of the CSDGM. Elements shown with a green asterisk (*) will be automatically updated by ArcCatalog. ArcCatalog adds hints indicating which FGDC elements are mandatory; these are shown with gray text.

Process step:
Process description:
1992 political map was heads-up digitized from the 1995 orthophotographs and a shapefile was created. A base ArcInfo coverage of correct linework (snapbase.e00) for all DC data was developed after the final delivery of the planimetric street centerlines. The political datasets were selected using the above shapefile from the snapbase coverage, creating coincident geography with the other DC GIS datasets. The resulting planimetric features were built as lines and converted to polygons. 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). The three political jurisdictions were created together since they share partial topology and nest partially within each other. Generally, a street centerline is used as a boundary. Line coverages, containing the polygons bounding attributes, accompany all polygons and are made available for editing and updating purposes.

Attribute data was provided by public record. 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.
