(ua-cam.com/video/XVjq45YSjsY/v-deo.html, ua-cam.com/video/BI5sZn5KhMY/v-deo.html) you can take help of these two videos for calculating weightage of respective thematic layers, which you can use in raster calculater as used in this video (my landslide suceptibility map).
I tried this exactly the same way and the raster calculation kept failing, so I changed '0.33' to '3' in the calculation and it seemed to work. Just a tip for anyone experiencing the same problem.
hi Zohaib, i thought every input parameters in my model have same weightage thats why i gave 0.33 for each thematic layer. when you are giving weightage make sure the total addition should be equal to 1. however for weightage calculation you can use AHP, logistic regression, ANN methods which is quite acceptable.
dear sir actually i am going to do my research project on landslide susceptibility modeling using SMCE (spatial multi criteria evaluation model ) that uses the process AHP i am really so confused with all that assigning weightage to different factor. many thanks
@@litanmohanty9148 yes but most of d research papers i went thru is mentioning a specific type- statistical, quantitative etc & d sub type in that...all r GIS based...so ..a more direct terminology 4 d type u used will b helpful..4 research purpose 2 mention in the methodology part
Hello, thank you Sir for this video, but it is still needs audio and more text explanations step by step. I appreciate your efforts.
What is the utility of using 0.33
Good job sir ! I have one request, can you show how to perform landslide susceptibility mapping using weight of evidence approach.Thank you.
sure, just give me some time.

Dear sir, what was the last step involving the raster calculator for?
its basically used for integration of all the thematic maps. i just add these thematic map by multiplying some weightage value.
Can u plz tell how to use a combination of frequency ratio and logistic regression
why we are taking 0.33 as weightage
Wooow...
Very Helpful! Could you please tell me what you did in the end using raster calculator and giving the value 9. Thanks!
thanks sumeet for your interest; there i am trying to highlight the area with raster value >=9.(higher probability zone).
Thank you for the information sir. It would be great if you could teach us the weight of evidence and information value method.
sure i will do it, but need some time...thank you.
dear sir, I want to know how to do landslide susceptibility mapping using logistic regression model. please reply.
thanks aneesah for your interest. you just see this video and follow some journal related to logistic regression based landslide probability mapping

Ohk then what value should we place at the last step in raster calculator?? As shown in the video he was placed >=9...
@@renuadhikari1649 erm, I'm sorry i have no idea was quite a while ago. I'd just have a play around and see what works. Sorry I can't help
why did you give 0.33 for landsliding?

I am pretty new to this type of study. Can u pls mention the name of this type of modelling?
U can called it GIS based modelling

AHP method
