Suitability Analysis using Weighted Overlay Method in ArcGIS

[@joelndayisaba904]

Awesome, this is so how interesting so keep it up.

[@GeoscienceSolutions]

Thank you Joel

Thank you for such a simple well-explained video!

[@assadullahrezayee186]

very interesting video, could you please make a video to show the best route for an overhead power transmission line from A point to B point ?

[@GeoscienceSolutions]

I'll put that into consideration

[@wyclifeoluoch9376]

Awesome! This is so interesting. Am curious about when we have a binary layer of 1 or 0 instead of 1 to 5 classes. For example, whether the area falls within Nairobi National Park (1) or not (0). With 1 being unsuitable and 0 being suitable. Would such a layer still be used with others having 1 to 5 values? Or we can use it later to clip the suitability map generated by other 1-5 scaled layers.

[@GeoscienceSolutions]

What you will do is after doing suitability analysis, mask out the area having the national park if you have it's boundary shapefile. That way, when accessing your suitable areas, you will only see those not withing the national park

[@samrusaati9173]

thank you for this tutorial. Question: how to calculate the surface area ( km2) for each weighed area? Thank you

[@GeoscienceSolutions]

You can calculate area using the calculate geometry tool

[@FaizalKasim_UNG]

Another way is to convert the raster result into a polygon which each area class you can get by doing Field calculate

[@priscillahwambui9546]

Can this also be used when you have existing businesses for example and you are looking for something like expanding? How do you carry out intersection between most suitable areas and areas that have existing businesses?

Lovely video. Having issues with my weighted overlay Its not displaying on my map plus the values also came out in ranges and decimal. Help pls

[@judymangaliwan4307]

Hello. May I ask, where that data came from? Did you make that data?

[@GeoscienceSolutions]

It's mock data.. But you can try and search online for real data

[@SachinSingh-gr5zn]

Is this tool available in QGIS?

[@ghassanjenainaty4212]

Is this ArcGIS pro or ArcMap ? I am using ArcGIS pro

[@GeoscienceSolutions]

It's Arcgis

I am using the weighted overlay tool to do a AHP modelling using five parameters. I have reclassified the parameters and only then doing the weighted overlay function as shown in the video. But still in the final output my Overlay layer contains 4 classes only, whereas i need 5. I have also tried to manually change the number of classes to 5, but it does not work. Please help me regarding this problem.

[@yldrmkaragiyim6609]

hello i am having the same problem. What solution did you provide?

[@suktiprajnarath3843]

i am having 3 classes ..but i need 5....anybody has the solution? please help

[@deepangshuchandra6123]

Actually as far as my understanding the algorithm automatically clears out classes with null values, or those which contain duplicate values. The end results i think are not being affected by the omission.
