Phase IV - Spatial Data Validation

Several fields were added to maintain consistency with the DCGIS spatial data model ([OBJECTID], [AID], [WEB_URL], and [UPDATE_DATE]). Two additional fields ([LABEL] and [NR_ELIGIBLE]) were incorporated into the updated dataset. [LABEL] is used to indicate a feature's name on a display or map. [NR_ELIGIBLE] is a flags that indicates whether the feature is eligible for entry in the National Register list.

DCOP and Historic Preservation staff performed a visual validation of the Landmark Areas dataset. Area boundaries were plotted and checked against DRAFT vectorized lot lines (Tax lot / Record lot), as well as planimetric features, as needed. Numerous new Landmark areas and Historic Districts were added to the dataset.

Phase V - Spatial Data Validation

All address points have been validated against the Master Address Repository (MAR) dataset and the current DRAFT Taxlot and Recordlot property boundaries.

Only the first 93 entries from the Inventory of Historic Sites document were validated in this phase, plus updating the attribution of the Landmark Areas / Historic Districts dataset. This constitutes the first major section of the document, "The Federal City". Subsequent document chapters will be processed and validated sequentially.

After the major issues were addressed, Historic Preservation Staff reviewed the Location and names of all landmark structures and sites within the dataset.

Proof maps were generated and changes or updates were noted where appropriate. DC Office of Planning GIS Staff reviewed and prepared the updates.
Process description: Boundaries of 16th Street Historic District and Greater 14th Street Historic District modified to reflect expansion of these districts.
Foxhall Historic District feature dataset added.
Schema revised. Updates from 2006 through 2011
