Data Quality Information
- Quantitative Attribute Accuracy Report
- Evaluation Method
- Digital databases created within the USBR was reviewed using existing quality standards.
- Result
- Good
- Absolute External Positional Accuracy
- Evaluation Method
- Error in digital capture of boundaries is estimated as 12 meters based on use of the USGS 1:24,000-scale quadrangles. Errors can be higher than 12 meters so use data with caution.
- Result
- Unified Code of Units of Measure m 12 meters
- Lineage
- Process Step
- Description
- The canals were only digitized in as center lines. Data are digitized using a Calcomp 9000 digitizer and Arc/Info using the established quality control standards of the U.S. Bureau of Reclamation, Mid-Pacific Region, MPGIS Service Center.
