Probability Based Analysis?

ArchTim — Thu, 27 Nov 2025 03:03:10 GMT

I'm on Arc GIS Pro - and I'm looking for a tool that can create a layer that includes probabilities. At a fundamental level I would like to create H3 Hexagons and have a model assign probabilities of finding an object within those hexagons based on specific spatial criteria. I only know a general area of where the object is so it would be helpful to be able to update the probabilities based on not finding the object within a hexagon.

Does the software have any capability for this type of analysis?

Thank you so much for your help!

Tessalations are available in

Generate Tessellation (Data Management)—ArcGIS Pro | Documentation

Have you ruled out what is available in the Spatial Statistics extension?

Some specific examples may guide further suggestions.

I’ve dealt with this in ArcGIS Pro before, and yeah, you can build H3-style hex grids and run a probability model on them. Using Spatial Analyst and ModelBuilder, you can update probabilities as you clear each hexagon, which really helps narrow down search zones. It takes a little setup, but it definitely works kind of like how APK makes editing easier once you know the tools. Hope this helps, it saved me a lot of time too.
