- Abstract:
-
Address Alias Point locations. The dataset contains locations and attributes of Address Alias points, created as part of the Master Address Repository (MAR) for the D.C. Office of the Chief Technology Officer (OCTO) and participating D.C. government agencies.
It contains the addresses alias names in the District of Columbia which are typically placed on the buildings. These alias names represent named features such as:
- Schools
- Federal Buildings
- Military Installations
- Hospitals
- Museums
- Monuments
- University Structures
- Fire and Police Stations
- Libraries
- Metro Facilities
- Historical Landmarks
- Recreation Centers
All DC GIS data is stored and exported in Maryland State Plane coordinates NAD 83 meters.

Data believed to be complete and accurate, subject to change. In process of validation by source and/or responsible agency.
OCTO GIS staff review a sample portion of the alias records.
- Logical_Consistency_Report: Validated by source and/or responsible agency
- Completeness_Report:
-
The address alias points contain most of the categories of landmark and key named features in the District, as of current project requirements. As these requirements change, additional categories may be added.

- Horizontal_Positional_Accuracy_Report:
-
Building centroids were generated using ArcGIS and used to generate the first pass of MAR points. On the second pass, it was found that the OwnerPts were not always on buildings and therefore had to be moved to the building centroids. Wherever building footprints did not exist in the building layer but the building appeared on the ortho, a visual center of the building on the ortho was used.

- Process_Description:
-
OCTO GIS used the names and addresses from the feature layers in the DC GIS database to create aliases in the DC Master Address Repository (MAR).
1. Staff geocode the feature layer to the MAR. This determines which features are in the MAR and which ones need to be added.
2. Staff then research and verify addresses for the rejected features and prepare them for inclusion in the MAR.
3. The feature names are standardized and completely spelled out (no abbreviations).
4. The names are added to the alias tables in the MAR using the MAR address ID and the feature name.
Since some named places in DC are known by several names, the alias layer contains stacked points. Each point represents an alias for the named place.
