Title:
Middle School Attendance Zones of Loudoun County, VA (Current School Year)
Geospatial_Data_Presentation_Form: vector digital data
Description:
Abstract:
This file contains every middle school attendance zone for the Loudoun County Public School System (LCPS). These attendance zones are updated on a yearly basis and are valid for the current school year only.
Purpose:
The data set was created by the LCPS's Department of Planning and Legislative Services to plan for classroom size and assign students to middle schools.
Supplemental_Information:
Data are stored in the corporate ArcSDE Geodatabase as a polygon feature class. The coordinate system is Virginia State Plane (North), Zone 4501, datum NAD83 HARN.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Retention of attribute 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, 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.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
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%.

Process_Description:
This school zone layer has the potential for new school zones and corresponding boundary adjustments before the beginning of the current school year. This is due to new schools being opened for the new school year.

Process_Description:
This data set was part of a batch process that converted legacy data from ArcInfo coverage in Librarian to a single-tiled ArcInfo coverage in preparation for a final conversion to ArcSDE Geodatabase Feature Classes. Data were extracted from Librarian using the EXTRACT TOPOLOGICAL command. Multi-tiled data sets were extracted into multiple coverages and then combined based on the feature type(s). Layers with both polygon and arc feature classes were processed with the Arc commands MAPJOIN and DISSOLVE. Arc feature classes alone were processed with the Arc commands, APPEND and DISSOLVE. Layers with both arc and point feature classes and point feature classes alone were processed with the Arc command, APPEND. When used, the arc command, DISSOLVE, was given with the <#all> option. All coverages were then reprojected to HARN83 using the following .prj file specifications: INPUT PROJECTION STATEPLANE UNITS FEET ZONE 5551 DATUM NAD27 NADCON PARAMETERS OUTPUT PROJECTION STATEPLANE UNITS FEET FIPSZONE 4501 DATUM HPGN NADCON PARAMETERS END The dataset was then converted to a feature class in a geodatabase in ArcSDE.
