Abstract:
WWTP_FENCE identifies the town of Lovettsville's Waste Water Treatment Plant perimeter fence boundary. Waste Water from the town is collected & treated at this location. |
Metadata elements shown with blue text are defined in the Federal Geographic Data Committee's (FGDC) Content Standard for Digital Geospatial Metadata (CSDGM). Elements shown with green text are defined in the ESRI Profile of the CSDGM. Elements shown with a green asterisk (*) will be automatically updated by ArcCatalog. ArcCatalog adds hints indicating which FGDC elements are mandatory; these are shown with gray text.
WWTP_FENCE identifies the town of Lovettsville's Waste Water Treatment Plant perimeter fence boundary. Waste Water from the town is collected & treated at this location.
WWTP_FENCE is used to provide the spatial location of the Waste Water Treatment Plant. This layer, along with LVILLE_SANITARY_MANHOLES can be used to spatially identify the town's waste water treatment network.
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), 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.
Retention of coordinate accuracy throughout the personal geodatabase or shapefile to ArcSDE geodatabase feature class conversion 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 the same record total, and on a record by record basis, area, perimeter, and length differential of less than +/- 0.5%.
Request by Karin Fellers, Town of Lovettsville Project Manager, to map the location of treatment plant for town mapping purposes
GPS collection of fence boundary while performing latest gps collection/update on 10/18/2010. Walked inside perimeter of fence while collecting a line feature. GPS data downloaded from unit & then differentially corrected in GPS Pathfinder using base files from CORS at Hagerstown, MD. The Standard Automatic Code Correction process was used to correct the data, which resulted in a predominately sub-meter accuracy of .5 to 1 meters (1.5 to 3 feet).
