  3. What similar or related data should the user be aware of?


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

  1. How well have the observations been checked?

    Attribute accuracy tested manually by comparing data to source materials.

  2. How accurate are the geographic locations?

    Horizontal positional accuracy tested by visual comparison of the data with hard copy maps and on-screen with existing data sets that cover the same area.

  3. How accurate are the heights or depths?

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

    Data set was created from all available sources - using legal descriptions (township, range, section) from Public Law 104-333 and a map from the Southwest Land Resources Program Center. Data is considered complete.

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

    All polygons are closed and adjacent polygons do not have identical attributes. Each polygon has one and only one attribute.


How can someone get a copy of the data set?

Are there legal restrictions on access or use of the data?

Access_Constraints: none
Use_Constraints: none
