- Abstract:
-
This dataset identifies existing telecommunication sites in Loudoun County, VA.
- Purpose:
-
Telecommunication is used to show the existing telecommunication antenna sites in Loudoun County. The coverage includes antennas mounted on buildings as well as mounted on a tower or monopole. It can also be used to analyze existing signal propagation and plan for new telecommunication antenna sites in Loudoun County.

-
- 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.

-
- 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%.
- Quantitative_Horizontal_Positional_Accuracy_Assessment:
-
- Horizontal_Positional_Accuracy_Explanation:
-
"Any features captured in Phase III (2005 data) were compiled to meet ASPRS and NSSDA standards for Class I map at 1:2400 scale, but a rigid accuracy test was not performed."
