How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

    Attribute accuracy is unknown. Each district enters data using the BLM IRDA edit toolset, based on restorations activities funded by BLM. Scale and accuracy is variable based on how the data is collected and digitized into the system.

  2. How accurate are the geographic locations?


  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

    This theme covers BLM managed lands in Oregon and Washington. Completeness is variable across districts.

  5. How consistent are the relationships among the observations, including topology?

    Consistency is variable across districts. Consistency is based on how the data is collected and digitized into the system for each district.
