Abstract

Metro Entrance Structures - DC only. This dataset contains polygons representing Metro Parapets, Canopies, and Buildings surrounding or enclosing metro entrances. This was 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.

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.

Access constraints

Contact OCTO GIS. Any data obtained outside of OCTO GIS are unauthorized copies.

Logical consistency
Not validated by source and/or responsible agency.

Completeness
Data believed to be complete and accurate, subject to change. Digital version compared with original source data for accuracy and completeness. In process of validation by source and/or responsible agency.

Horizontal positional accuracy
Digitized off of the 2005 planimetrics and orthophoto which were captured at 1:1200 scale. The planimetric data has a one foot accuracy.

Vertical positional accuracy

Staff reviewed all Metro Station Entrance Points to find structures visible in the 2005 Orthophotography. Parapets, canopies, or buildings were digitized into polygons for those entrances that clearly showed a surrounding or enclosing structure. Not every metro entrance has a structure contained in the layer. For instance, metro entrances at Union station are not included in the layer because they are enclosed in a much larger structure.

Corresponding GIS_ID from MetroStnPt were copied over to each Metro Station Parapet.

Distribution

Most DC GIS datasets can be downloaded from "http://dcgis.dc.gov" on the data center page. Orders can also be made by contacting OCTO GIS at "dcgis@dc.gov", especially for datasets not available for download.
