[Qgis-user] Technical help needed

[chris hermansen]

I see a considerable number of references that turn up on a search for
"Kriging safe bearing capacity"; for example this

https://link.springer.com/article/10.1007/s12665-021-09971-2

Looking in the other direction "qgis kriging interpolation", lots of
references about how to perform kriging, for example this course

https://giscourse.online/kriging-in-qgis-ultimate-guide/

As always it's most important to recognize that this is interpolation,
which requires assumptions of the nature of the distribution of properties
of the physical material being analyzed; which a decently suspicious
engineer should consider as "unfounded" unless they have evidence to the
contrary.
