GIS polygon dataset for Mississippi of the USGS Public Land Survey System (PLSS). Data digitized from USGS 7.5 minute topo maps (paper) dated between 1960 and 1989. Data contains survey district, section, township, range number attributes , and annotation. *** Data was merged to form the statewide file in 2005 and corrected using new USGS DRGS dated through 2004. +++ Further corrections were made by MS Department of Transportation staff 2007/2008. Note: Attribute miscodings were found by Pete Kohn of the MS Development Authority and James Smith of the USDA/FSA - MS Office. Those corrections were made and incorporated into this version of the data set. Corrections to sections along the MS River in Washington and Issaquena Counties were made by MARIS staff in April 2010. These miscodes were found by Michael-Baker Engineering and Waggoner Engineering.
This data was collected for use in a right-of-way acquirement and statewide redistricting in 1990. MARIS staff merged the county data and edited this data with USGS DRG data through 2004.
Sections that crossed county lines were merged to form single polygons.

Attribute values were validated via cross-checks with exisiting data resources including photographs, maps, imagery, and scientific reports.
All line work is checked for topological integrity and to ensure that polygons are fully enclosed, no duplicate lines or points exists, line segments are composed of sequentially numbered coordinate pairs, intersecting lines are separated by a node, and no dangling lines exist. Topological checks and strucuturing are performed using the ArcInfo software. Data dictionary specification are automatically implemented via the ESRI Info database management software. Data collected from external data providers are randomly verified.
The data are complete with respect to the data publication date and scale.
Feature locations were were validated via cross-checks with exisiting data resources including photographs, maps, imagery, and scientific reports.
primary data source
This data was used to correct the county lines and state border for the statewide file.
USGS data by county were merged by MARIS staff to create a statewide file. The updated USGS DRGS were used to edit the county boundaries and state outline. If sections split county lines, they were merged to form a single polygon.
MS Department of Transportation staff found minor topology errors in the linework during late 2007 and early 2008. Those changes were incorporated into this version of the data set. Corrections to miscoded attributes found by Pete Kohn of the MS Development Authority and James Smith of the USDA/FSA - MS Office were made by MARIS staff.
Michael Baker Engineering and Waggoner Engineering found coding errors along the MS River in Washington and Issaquena counties respectively. Corrections were made by MARIS staff in April 2010.
