- Abstract:
-
This feature class includes existing and planned alignments, functional classification, planned interchanges, scenic byways and ultimate roadway geometry for all of Loudoun County. Please note that the planned roadway alignments shown are conceptual and are subject to further engineering. Loudoun County recognizes the importance of roadway planning by including existing and planned roadway alignments as a map element of the Revised Countywide Transportation Plan adopted on June 15, 2010.
- Purpose:
-
The purpose of this data set is allow reproduction of the official CTP map(s), or sub-area maps for use by County elected officials, County staff and the general public. This data cannot be changed or modified without going through the appropriate Loudoun County CPAM procedure with Board approval.
- Supplemental_Information:
-
This layer's alignment follows street centerline and identifies the special designations of planned and existing roadways in Transportation Plan. Data are stored in the corporate ArcSDE Geodatabase as a point 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.

-
- Attribute_Accuracy_Report:
-
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.
- Logical_Consistency_Report: Topologically clean
- Completeness_Report:
-
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.

- Horizontal_Positional_Accuracy_Report:
-
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%.
