            <abstract>Tree Points are a base map data layer derived by automated processes and processed for cartographic representation at 1:2400 scale.  The point features represent any isolated, visible, single standing tree as seen from above and are mapped to National Map Accuracy Standards (NMAS).  These may be orchards, single specimen trees or rows of landscape tree features that together do not comprise a polygonal forest feature.</abstract>
            <purpose>Tree Points are used by both the private and public sectors for comprehensive and facility planning, conservation and preservation projects, and site design.</purpose>
            <supplinf>Loudoun County has been maintaining Base map data layers since 1980.  A complete, Countywide remapping project, conducted in two phases, has yielded the current data set.  Phase I, using 2002 Virginia Base Mapping Program (VBMP) digital scanned imagery, and Phase II, using 2004 scanned aerial photography comprise the initial re-map effort.  See "Source_Contribution:" for extent of Phase areas.  The project was completed in 2005 and now undergoes annual updates, with the next one occurring in Spring 2007.
   Many annual cycles (2005 to present) of base map update contribute to the development of this layer.  OMAGI updates all base map data selectively according to development patterns; therefore some feature data may not be current.  Various parts of the County are updated from aerial photography through stereocompilation and photogrammetry.  Ground features are captured and attributed through the base map maintenance services contract kept by the County.
    Data are stored in the corporate ArcSDE Geodatabase as a line feature class.  The coordinate system is Virginia State Plane (North), Zone 4501, datum NAD83 HARN (vertical datum, if applicable, NAVD88 HARN), US Survey foot units.</supplinf>

        <complete>Base Map features are updated periodically in areas of highest development throughout the County.  Consequently there is a mixture of features from different sources and different years.  Although the entire County was originally mapped, users should be cautious and aware that any particular area of interest may not be absolutely current and up to date.  A generalized map of update years can be located at http://inetdocs.loudoun.gov/omagi/docs/basemap_/updatestrategy/updatestrategy.pdf.  The next anticipated update shall occur using Spring 2007 imagery.</complete>

                <horizpar>A random sampling method was utilized to locate thirty points each over the Phase I (2002 data) and Phase II (2004 data) Project areas to be used in the accuracy assessment.  Once the random points were visually located on the digital maps a survey crew was dispatched to obtain GPS coordinates of these points.  In addition existing digital orthophotos were used to aid the surveyor in the field to locate the points.  Only points or intersecting features were used from the photogrammetrically compiled planimetric maps.
     From the thirty points randomly selected, each point was surveyed using Ashtech Z-12 dual frequency GPS receivers in static mode in a geodetic network format as specified in the FGCS Guidelines.  Fixed height tripods were utilized on all stations.  GPS raw data was processed with the Ashtech Office Suite (AOS) data reduction software producing vectors to all common networked session points.   All vector data was entered into the StarNet Least Squares Adjustment program. Initially a minimally constrained adjustment was produced resulting in relative component point error ellipses at the less than 0.10 foot level of accuracy.  This provides the location of the reference data for the accuracy assessment calculations. Utilizing the sketches, Northing , Easting and Elevations of each of the points were  measured by a stereocompilation technician.  The photogrammetrically determined values are coincident with the final coordinate values in the digital data.
     To complete the accuracy assessment NSSDA (National Standard for Spatial Data Accuracy) the two measurements are compared and a circular root mean square error (RMSE) is calculated.  A spreadsheet was prepared with the measurements and results of 25 points in Western Loudoun (Phase I-2002) and 23 points in Eastern Loudoun (Phase II-2004).  These calculations were made according to Chapter 3, National Standard for Spatial Data Accuracy, Geospatial Positioning Accuracy Standards, FGDC-STD-007.3-1998: Washington, D.C., Federal Geographic Data Committee, 1998, 28 p. The report can be downloaded from http://www.fgdc.gov/standards/status/sub1_3.html.
    The resultant accuracy of the measurements yields a circular RMSE of 2.0 US Survey feet (Phase I-2002 data) and 1.1 US Survey Feet (Phase II-2004 data) in the horizontal domain.</horizpar>

  The Aerial Triangulation was performed using softcopy workstations.  Bundle adjustment was performed and Digital Elevation Models were created using and planimetric data were collected using standard photogrammetric collection techniques for breaklines and masspoints on soft copy workstations.

Tree [Type = 1]
    Any isolated, visible, single standing tree or row of trees, less than 15' wide, where individual trees are separated by an average distance of greater than 10' apart.  Digitize center of trunk where trees are not too close for individual plotting.  Should NOT include small trees (&lt;6' tall), shrubs and other small garden or home landscape features.</eadetcit>
