Attribute accuracy is tested by manually comparing hard copy plots of the digital data with source materials or by interactively querying and verifying on the screen.
The data has been checked to make sure that all intended polygons are closed, that there are no unintended undershoots, overshoots or dangles and that there is only only label point per polygon. This does not preclude the presence of one or more of these errors.
This coverage is in draft format. Verification by the appropriate BLM Field Office is needed.
Approximately + or - 40 feet. Test by visual comparison of hard copy check plots against source material and/ or verfying the location of the data on screen relative to other data layers in the same geographic area.
None.
Vector data representing BLM designated Areas of Critical Environmental Concern boundaries.
Data were compiled on 1:24000 scale USGS paper quads and digitized from those quads. Some of the original ArcInfo coverages were converted to shapefiles and edited in ArcView while others were edited in ArcEdit. Shapefiles were converted back coverages and Individual files were then merged into a single statewide coverage. Data was checked on screen against other data layers in the same geographic area.
