I want to reclassify my raster layers to run a weighted overlay analysis.
I want to identify the most dangerous vs. least dangerous neighbourhoods in an area based on weighted crime indicators using a crime severity index. How would I reclassify each of these layers?
I would set each of your crime indicators to a scale of 1 to 10. You can use the Rescale by Function tool to do this. I like the Power option, but you can use Linear, Logarithmic, Gaussian, Exponential or others.

Then after you've set them all to that scale of 1-10, then use the Weighted Sum tool, setting your weights accordingly.
