Loudoun Forest

More MetadataForest tracts is a base map data layer derived by automated processes and processed for cartographic representation at 1:2400 scale. The polygon features represent the areas of forest or scrub cover as seen from above and are mapped to National Map Accuracy Standards (NMAS). Forest is used by both the private and public sectors for comprehensive planning, facility planning, preservation projects, site design and land cover analysis.

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, NAVD88, US Survey foot units. OMAGI updates all base map data via a photogrammetric process, using aerial imagery that is flown yearly in phases. A different portion of the County is updated each year with the base map maintenance services contract, depending upon development patterns and update funding. See "Lineage" section for the list of extents for each Phase area, which are listed as “Data Sources”. The field “UPD_DATE” indicates the date a feature was last re-mapped, although it may have been reviewed for changes more recently.
