You can watch a video titled "Step-by-step Procedure of Multi-criteria Decision Making (MCDM) analysis using GIS and AHP - Part 1" in this UA-cam Channel to easily understand how to assign weight of influence for each factor.
I am working on a suitability analysis using the Weighted Overlay method in ArcMap based on the Analytic Hierarchy Process (AHP). After performing the study, I encounter issues when classifying and visualising the output. Here are the problem details: When attempting to classify the Weighted Overlay output, I receive a prompt to compute the histogram. Upon clicking "Yes," the software fails to initialize the classify renderer and displays an error message stating: “Failed to initialize classify renderer (possibly too many unique values).” The output data appears to have a very high number of unique values, which seems to be causing issues with classification and visualization. The classification settings are not rendering the data properly, and the map APPEARS EMPTY. What could be the problem? I've failed to get an output suitability map. I have 16 factors.
There's no sound in this video,
How can we get weighted factor value?
