This interview produces the map of ordinary kriging variances for the selected contaminant. When this interview is selected, ordinary kriging is the only available interpolant in the Interpolation Methods step. If OK was not previously selected , SADA will warn the user and automatically change the interpolant to OK for the user.
Availability
This interview is available for all analyses that have sampled data (unpooled only), with all data types except Geobayesian. It is only available for the ordinary kriging interpolant.
