  1. Provide Evaluation Documentation

  2. Rationale Prior to any Project soil survey update activities, an evaluation of the overall condition of the original map units are required. A written summary of the evaluation must be a component of the process in order to allow development of conclusions and a comparison of situations on the Project within a MLRA.

  3. Objectives • Identify methods used to document map unit evaluations • Identify where to record evaluation documentation in NASIS • Identify report that can be used to retrieve evaluation data entered in NASIS • Illustrate the importance of aggregating evaluations in the context of the MLRA

  4. Background • Evaluate - to determine the significance, worth, or condition of usually by careful appraisal and study. (Implies comparison) • Standard - something established by authority, custom, or general consent as a model or example. (Synonym = criterion) • Ask questions and make related observations in order to discover whether the map units in the Non-MLRA Soil Survey products meet the current NCSS standards.

  5. Evaluation Methods • Soil survey manuscript and archive data review • Validations, queries, or reports using NASIS • Spatial evaluation using GIS applications (WSS, SDV, ArcGIS) • Soil survey users group and technical team meetings

  6. Document evaluation methods and results in either the NASIS Legend Text or Mapunit Text table as appropriate.

  7. Choose “miscellaneous notes” for the Kind field.

  8. Populate the Category field with the term “evaluation”

  9. Populate the Subcategory with an appropriate term from the following list. attribute spatial interpretations

  10. Summarize Evaluation Results • Attribute (maintenance) • Spatial – export attribute data and either join or relate them to SSURGO data (extent, landforms, joins) • Interpretation (enhancement) • NASIS report to summarize evaluations by SSA and/or map unit (replaces NSSH Exhibits 610-1 and 610-2)

  11. NSSC Pangaea Site MLRA –mgnt- Survey Evaluation notes for long range planning

  12. Summarize Evaluation Results (cont.) • Evaluate in the context of the entire MLRA • Split map units mapped outside the extent of the designed concept • Correlate synonymous map unit concepts on the same landscape together

  13. Evaluation Workload • First milestone associated with the Project • All map units will eventually be associated with an evaluation

  14. Conclusions and Comparisons • Compare and aggregate evaluation summaries • List deficiencies discovered • List is ranked • Manage projects in NASIS 6.X project object

  15. Questions or comments?
