  2. What changes have been made?

    Date: not complete (change 1 of 4)
    Data was assembled using information from the Oregon State Office and from various federal, state, and county agencies. When data from multiple sources covered the same area, the data was then assessed for best quality content and accuracy. Priorities were determined for acceptance. Data with positional accuracy statements were first choice (GCDB data). Data with accuracy statements in the meta data were second, and data without accuracy statements was the third priority for acceptance. The data was then combined with and edge matched to previously accepted data and adjusted to conform to the topology rules.

    • GCDB

    Date: 20091023 (change 2 of 4)
    Washington state data extracted from equivalent WA_LLI theme (WA_SubsurfaceRights_poly). Any overlaps with existing Oregon data in SUBSURFACE_RIGHTS_POLY were resolved by deleting features from SUBSURFACE_RIGHTS_POLY. Field VERSION_NAME of the Washington data was filled with the value "InitialLoad". Values in Washington field SUBSURFACERIGHTSCODE were translated to SUBSURFACE_RIGHTS using crosswalk information approved by data steward Tim Keck. Washington data loaded into SUBSURFACE_RIGHTS_POLY. Edge-match of data along the Oregon and Washington border was completed by Erin Frostad using GCDB points.

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

  1. How well have the observations been checked?

    Attributes were compared with the source material for accuracy. Discrepancies were cross checked with other sources to determine and confirm the correct attribute.

  2. How accurate are the geographic locations?

    Source Data derived from the BLM addresses positional accuracy by referring to the error ellipses from the Geographic coordinate data base (GCDB). Other Source data derived from other Federal, State, and county sources as a rule did not address positional accuracy. Accuracy was then determined from metadata statements if available.

  3. How accurate are the heights or depths?

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

    This theme covers the states of Oregon and Washington.

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

    The Subsurface_Rights_Poly was built for polygon, arc, and node topology.
