Title: Bus Routes of Loudoun County, VA (2012)
Geospatial_Data_Presentation_Form: vector digital data
Description:
Abstract:
The routes of each bus service are based on Street centerline. Street centerline was originally developed from the road features on the County's 1:2400 base map. The current data is collected from recorded plats in DXF format or is digitized from plats. The route data is collected by the Office of Transportation Services . The data covers the serviceable area of Loudoun County as well as the incorporated Towns.
Purpose:
The bus routes coverage was developed to support the Office of Transportation Services. OTS uses the data to display serviceable areas and adjust routes and stops based on the needs of ridership. The following bus routes are represented in the data: Route 40, Purcellville Connector Route 50, Leesburg Safe-T-Ride Route 51, Leesburg – Battlefield/Ida Lee Drive Route 52, Leesburg – Sycolin Road/Miller Drive/ South King Street Route 53, Leesburg – Trolley to Leesburg Outlets/Shenandoah Building Route 60, Ashburn Village Connector Route 61, Ashburn Farm Connector Route 70, 7 to 7 on 7 Route 80, Sugarland Run Connector Route 81, Countryside Connector Route 82, Sterling Connector Route 83, Dulles 2 Dulles Connector Route 84X, Herndon Monroe Connector
Supplemental_Information:
Data are stored in the corporate ArcSDE Geodatabase as a line feature class. The coordinate system is Virginia State Plane (North), Zone 4501, datum NAVD88 , US Survey foot units.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
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.
Logical_Consistency_Report: Topologically clean
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
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%.
