Description:

Abstract:

This data set identifies properties that participate in and are part of Agricultural overlay districts according to State enabling legislation per the Virginia State Code, Chapter 43, Section 15.2, Agricultural Districts.  Economic Development administers the County's Agricultural District program.  A parcel is not the smallest unit within an Agricultural District.  A portion  of any parcel can be in or out of a district, through appropriate reviews, without an official subdivision.

Purpose:

This layer identifies properties within each of the Agricultural Districts, which are used by participants to preserve farmland and open space through parcel subdivision restrictions.  Each Agricultural District has unique terms
and subdivision restrictions.

Supplemental information:

Maintenance has changed from a GIS or spatial based system to a tabular system. Currently Agricultural District (Ag Dist) data is maintained in LMIS through a custom interface with the LMIS database.  When Ag Dist data changes in LMIS, GIS must be updated.

Data are stored in the corporate ArcSDE Geodatabase as polygon feature class.  The coordinate system is Virginia State Plane (North), Zone 4501, datum NAD83 HARN (vertical datum, if applicable, NAVD88), US Survey foot units.

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 step:

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.
