Draw an Area of Concern Map - Interview

This interview will estimate the area of concern based on the current contaminant, interpolation method, and decision criteria.

Availability

This interview is available for all analyses that have sampled data (unpooled only) with all data types, including Geobayesian. In addition, it is available for human health analyses with pooled data.

Steps

These are the steps that display in the Steps Window when this interview is selected. Click on the links below for more details about the following steps.

1. See the data, Draw/Edit Prior

2. Set up the site (not available for Geobayesian data)

3. Set GIS Overlays

4. Set update data (only available for Geobayesian data)

5. Set grid specs (not available for Geobayesian data)

6. Interpolation Methods (this step is not enabled for pooled data with human health or Geobayesian data)

7. Correlation modeling (only available if OK or IK is selected under Interpolation method; not enabled for pooled data with human health)

8. Search neighborhood (only available if OK, IK, or Inverse Distance is selected under Interpolation method; not enabled for pooled data with human health)

9. Specify decision criteria (not available for Geobayesian data)

10. Set eco framework (only available for ecological analyses)

11. Show the results

12. Cross validation (this step is not enabled for pooled data with human health or Geobayesian data)

13. Format picture

14. Auto-document

15. Add to results gallery

When Show the results is selected from the Steps Window, SADA will ask for the decision criteria. This criteria will depend on the type of analysis.
