AOC Prior Boundary Sample Design

AOC Prior Boundary is a secondary sample design for Geobayesian data that generates new samples in locations with the highest uncertainty about exceeding the cleanup goal. This approach is useful for delineating the boundaries on an area of concern.


This sample design is only available for SADA files with Geobayesian data.


These are the steps that display in the Steps Window when this sample design is selected during the step Set sampling parameters. Click on the links below for more details about the following steps.

1. Draw/Edit Prior

2. Set up the site

3. Set GIS overlays

4. Set sampling parameters

5. Show the results

6. Import sampled data

7. Format picture

8. Auto-document

9. Add to results gallery

Design-specific Parameters

When AOC Prior Boundary is selected during the Set sampling parameters step, the Parameters Window changes to look like the following:


See Design Core samples or Show Ghost Image for an explanation of the core vs. single point sampling options.

Under Number of Samples, only you pick is available. Enter the number of samples in the space provided.

To use the secondary minimum distance constraint, enter a value next to Separate by at least.

Under Tie Break Options, select the appropriate tie break method.

Press Show the Results on the Steps Window and SADA will display the sample locations in the Graphics Window. If there are polygons, new samples will only be placed inside the active polygons.


To view the actual coordinates of the new sample points export the information to a comma delimited excel file by using the Output to File toolbar button in main form of SADA.
