Draw a Probability Map - Interview

This interview produces a map that graphically shows the probability of each block exceeding a specified value when using either ordinary kriging or indicator kriging. This value is either analysis-based or concentration-based, depending on the type of analysis. See Decision Basis.

Availability

This interview is available for all analyses that have sampled data (unpooled only), with all data types except Geobayesian. It is only available if ordinary kriging or indicator kriging is selected as the interpolant.
