Clarification on Weighting in Fuzzy Overlay Analysis for Spatial Research
Hello Esri Community, , I’m a GIS researcher from Ethiopia working on malaria risk modeling using spatial fuzzy logic. While reviewing literature, I noticed a contradiction: many studies apply weighting to factors in fuzzy overlay analysis, yet Esri’s documentation emphasizes that traditional fuzzy logic relies on set…

Grouping Points by Attribute to Create Polygons
I am looking for a way to group points (and create polygons if possible) using a numbered attribute. I have address points with a count of Living Units for each point. This Living Unit can be any number but usually falls from 1 to 48 (for apartment complexes). From here I would like to spatially group, cluster or aggregate…

Point density analysis
I have a point layer and each of the points is either category A or B. I want to find out if proximity to category B helps category A increase in weight. I have separated the file into two layers now; layer A (I have the weights of each point as a field here) and layer B. What sort of analysis can I do in ArcGIS Pro to…
