The land statuts attributes are a snapshot of the Land Information System Database and is only as accurate as that database. The data is produced down to the section (square mile) level.
This data layer is initially based on the BLM protracted township and section grid, but GIS processing is conducted in arcinfo and is 'cleaned' to create polygon topology. Clean process generates a coverage with correct polygon or arc-node topology. To do this, CLEAN edits and corrects geometric coordinate errors, assembles arcs into polygons and creates feature attribute information for each polygon or arc. Clean is executed againsta the statewide coverage and relies on a fuzzy tolerance that adjusts the input coverage and create small coordinate adjustments.
not assessed
This dataset is considered complete at the time of creation.
Polygon topology exists.
