Town boundaries are updated within 1-2 weeks of the date of receipt of recorded documents associated with annexations. Recorded documents are generally received from the Assessor's Office within 4-6 weeks of the date of recordation. Town boundaries are checked for coincidence with parcel boundaries approximately once every six months. Annexations occur fairly frequently in most Towns, often once a year. Parcels that are split by a town boundary are given unit numbers. For example, a MCPI (Map Cell Parcel Identifier) or PIN may be 123-45-6789. If this number was split by the town, the result would be 123-45-6789-001 indicating the County portion of that parcel, while the Town portion would be 123-45-6789-002. These units do not show in the County's GIS system, but are in the Assessor's database. Several Towns have an independent tax that is calculated from the pro-rated unit acreage. 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. 1 -77.776115 -77.403677 39.286619 38.918214 This metadata reflects the source Geodatabase format and specific elements may not apply if your data is exported to SHP or DXF products.

Retention of attribute accuracy throughout the coverage to geodatabase feature class coversion process was ensured by a 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. Retention of coordinate accuracy throughout the coverage to geodatabase feature class conversion process was ensured by a QA/QC programmatic check. To meet satisfactory QA/QC requirements the input coverage and output feature class must have the same record total, and on a record by record basis, area, perimeter, and length differential of less than +/- 0.5%. Leesburg, Round Hill, Hamilton and Lovettsville were all original mylar plats that were digitized in 1994. Dulles Int'l Airport was digitized from mylar plat in 1999. Middleburg was digitized from original tax maps. Loudoun County, VA, OMAGI Parcel Coordinator Hillsboro and Purcellville have no verifiable, recorded map source and comprise parcels identified by the Dept. of Financial Services as within those towns' limits. 1999-01-25T00:00:00 Loudoun County, VA, OMAGI GIS Analyst This data set was part of a batch process that converted legacy data from ArcInfo coverage in Librarian to a single-tiled ArcInfo coverage in preparation for a final conversion to ArcSDE Geodatabase Feature Classes. Data were extracted from Librarian using the EXTRACT TOPOLOGICAL command. Multi-tiled data sets were extracted into multiple coverages and then combined based on the feature type(s). Layers with both polygon and arc feature classes were processed with the Arc commands MAPJOIN and DISSOLVE. Arc feature classes alone were processed with the Arc commands, APPEND and DISSOLVE. Layers with both arc and point feature classes and point feature classes alone were processed with the Arc command, APPEND. When used, the arc command, DISSOLVE, was given with the <#all> option. All coverages were then reprojected to HARN83 using the following .prj file specifications: INPUT PROJECTION STATEPLANE UNITS FEET ZONE 5551 DATUM NAD27 NADCON PARAMETERS OUTPUT PROJECTION STATEPLANE UNITS FEET FIPSZONE 4501 DATUM HPGN NADCON PARAMETERS END The dataset was then converted to a feature class in a geodatabase in ArcSDE. 2004-01-19T00:00:00 Loudoun County, VA, OMAGI GIS Analyst Annexation Plats are incorporated into Town boundaries periodically upon their recordation.

Original source maps for existing data were unavailable, so these selected parcels formed the basis for these two Towns. Boundaries are thus dependent on original parcel plats comprising the towns. Maps at the town office in Purcellville were checked against against existing data. The source of the existing data could not readily be determined, but the existing data agreed with the Purcellville maps with the exception of recent annexations. The annexations were incorporated into the town boundary. 0 Tax Records for Hillsboro and Purcellville 1999-01-01 Loudoun County Dept. of Financial Services publication date 1999-01-01 County participates in a SDE Feature Data Set Topology called LANDRECORDS.
