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?
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.
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
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.
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.
Awesome, this is so how interesting so keep it up.
Thank you Joel
Thank you for such a simple well-explained video!

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
?
I'll put that into consideration
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
thank you for this tutorial.
Question: how to calculate the surface area ( km2) for each weighed area? Thank you
You can calculate area using the calculate geometry tool
Another way is to convert the raster result into a polygon which each area class you can get by doing Field calculate
Is this tool available in QGIS?
Hello. May I ask, where that data came from? Did you make that data?
It's mock data.. But you can try and search online for real data
Why is error coming im doing same

hello i am having the same problem. What solution did you provide?
i am having 3 classes ..but i need 5....anybody has the solution?
please help

Is this ArcGIS pro or ArcMap ? I am using ArcGIS pro
It's Arcgis
can you given shp
