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

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?

@ManishaKumari-xg6ki 2 года назад

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

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?

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

@aaronmaxwell7222 4 года назад

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

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
