DGS provided a DC property database which staff geocoded using SSL and ownerpoints as well as the MAR. Off the 3803 records provided, 133 could not be mapped.

in OCTO




OCTO GIS personell analyzed and combined several Portfolio managers lists with the existing DGS property master list to establish a comprehensive District property layer. Using vector property information and other property sources, OCTO GIS staff verified and cleansed these lists. Lots were removed that are no longer active since transactions (i.e. combinations, splits, superseding Air Rights & Tax Lots ) occurred and the new lots (replacements) supercede them. Staff identified new lots by ownership from OTR's property data to add to the master list
Also, a few in the list were removed due to street dedications.
