I tried to reclassify raster with your formula (min/max) and popup errror. You said that it is not possible to calculate it without statistics calculator? What is that and where is it?

[@navyageorge1956]

Hi, I am using Arcmap (desktop). I used the weighted overlay tool, but what value do I give nodata..if i do not give it a value it will spit out 0. If i assign it a value of zero it changes my scale

[@ManishaKumari-xg6ki]

I want to do suitability for vegetation. All my layers are vector. How can I reclassify them? ( criteria such as roads, builtup, vegetation etc)

[@viniciusantunes2161]

Thank you! Really good tutorial. Would you mind clarifying how do you come with numbers 41, 42 and 43 in the con function for the lca13.img?

[@grettelvargas4307]

hello one questions when you have many layers in differents scales from differents sources which the correct processs? put all in the same scale or that not afected the result thank you

[@afeworkabate810]

Sir what is the difference between Weighed sum vs Weight overlay pls

[@anshulrajput7092]

Do all the overlaying classes should have same number of classes ??

[@aaronmaxwell7222]

It is not necessary that they have the same number of classes, but they should be scored using the same range.

good

How do you do weighted overlay with attributes of vector data, not raster?

[@Guisantz]

I believe you must rasterize your vector, but i'm no specialist

[@yehuwayehuwa6046]

Hi Sir, can we calculate the risk assessment for example building of airports ( construction infrastructure) using weighted overlay to the location and resident around? How about the step for it? Thank you
