Abstract:
The original land grants are the orginal granting of land by Lord Fairfax and/or his agents during the settlement of Virginia and the formation of Loudoun County. Data was compiled through extensive research of deeds, plats, books, and maps by Loudoun County Historian Wynne C. Saffer. The original land grants are recorded on United States Geological Survey (USGS) Quadrangle maps, with a scale of 1 inch to 2,000 feet. |

The original land grants are the orginal granting of land by Lord Fairfax and/or his agents during the settlement of Virginia and the formation of Loudoun County. Data was compiled through extensive research of deeds, plats, books, and maps by Loudoun County Historian Wynne C. Saffer. The original land grants are recorded on United States Geological Survey (USGS) Quadrangle maps, with a scale of 1 inch to 2,000 feet.
Original land grants are used to approximately show where the original land grant parcels and boundaries are located and to whom they were granted. The intention of this feature class is for historical reference and is not recommended for any analytical purposes, as the boundaries are not accurately portrayed.
The original land grants identify the county in which the property is originally located at the date of the grant. The first grant in Loudoun County was issued in 1709 to Captain Daniel McCarty of Westmoreland County with 2993 acres. The property is described as being in Stafford County above the falls of the Potomac River, including Sugar Land Island. Prince William County was formed from Stafford in 1731. Fairfax County was formed from Prince William in 1742 and Loudoun was formed from Fairfax in 1757. Therefore, land within Loudoun County is described as Stafford, Prince William, or Fairfax prior to 1757 depending on the date of the grant. The Quadrangle maps containing the orginal land grants were scanned using a wide format scanner to create a digital file. The land grant boundaries were then digitized or coordinates entered via ARC/INFO Coordinate Geometry (COGO). Data are stored in the corporate ArcSDE Geodatabase as a polygon feature class. The coordinate system is Virginia State Plane (North), Zone 4501, datum NAD83 HARN (vertical datum, if applicable, NAVD88), US Survey foot units.

Retention of attribute accuracy throughout the personal geodatabase or shapefile to ArcSDE geodatabase feature class coversion process was ensured by a manual or automatic QA/QC programmatic check. To meet satisfactory QA/QC requirements the input coverage and output feature class must have, on a record by record basis, identical attribution when comparing all concatenated fields to all the user-defined attribution.
Topologically clean
Features may have been eliminated or generalized due to scale and intended use. To assist Loudoun County, Virginia in the maintenance of the data, please provide any information concerning discovered errors, omissions, or other discrepancies found in the data.
Please Note: The position, boundary, and size of land grants are not completely accurate due to several factors. First, the original surveys done on these properties contained many errors along with lack of technology. Errors in surveying led to many overlapping boundaries. There has also been a loss of documents over time on some of the land grants. These factors lead to much interpolation of the boundaries. Next, many boundaries drawn on the USGS Quadrangular maps were incomplete or drawn in a different position. This resulted in land grant boundaries that were located on two or more maps not connecting when place side by side together. In these cases, interpolation methods were used for best estimation of the location of the land grant boundaries.

Previous seven sources used to draw original Land Grant boundaries onto USGS Quadrangular maps to best of ability.
Original land grant boundaries for entire Loudoun County collected from several sources and drawn on USGS Quadrangular maps. See Source Information for detailed list of sources.
USGS Quads with original land grant boundaries scanned using a wide format scanner to create digital files. The files were burned to a CD and loaded into Loudoun County's GIS Catalog system.
The digital USGS Quad maps were geo-referenced for digitization of land grant boundaries. The geo-referencing places each digital map into its correct spatial location within Loudoun County. The original land grant boundaries were digitized into a new feature class by tracing over the boundaries on the scanned image.
A topology check was performed to make sure all lines intersected with no dangles and land grant polygons were built from the line work. Appropriate attribution was added to each land grant polygon.
