Sir can u please tell me the other method for landslide analysis like AHP, fuzzy overlay, and frequency ratio model etc as you have mentioned in the description box below.
Analytical heirarchy process that help us to develop regression coefficients that can be used during raster calculator and weighted overlay further it helps us to guide our decision taking multiple criteria.
sir i have a question how did u select 500 as the limiting value for landslide probable zones in the spatial calculator , is this the stndard value for earthquake delimitation or is it just area specific?
High value is 1.9 * 10^6 and you can collect and observe the situation of a place as you are familiar to how much flow accumulation can trigger the landslide at that place which becomes threshold value above which landslide getting chance is higher.
flow direction and flow accumulation determine the stream order using strahler method and result is based on method used and strahler method gives quite good result.

Hello Sir. If I were to add in e.g. Lithology Map/Rainfall Map, should I change the weightage so all my layers will sum up to 1 or 100%? Or is there another method? Thanks
Specially for the weightage I have used AHP method to calculate it in percent. If you want to add obviously there will be change in all weightage percent so that you have to provide new suitable weightage value to all layers and make their sum up to 100% as per priority or influence of layers. Hope i have met your question.
For the AHP method, can I assume the importances value for Pair Wise Matrix based only on my knowledge and objectives of the hazard map? Also, may I know if there are different method calculate the percentage of weightage? Just to have your opinion Sir, do you have any suggestions for a simple landslide hazard model that requires no expert opinion? I have limited resources such as DEM data, Lithology, Soil, Land Use, Rainfall and Topography Map only.
We can use landsat images dem , stream and road network as at the time of upload i have saved it as scratch data and lost it. So sry you can down road and stream data from diva gis .com rest data can be download from earth explorer 30 m resolution data. Hope it will help you. Thankyou for your precious comment.

Ohk thnku so much sir for the information
@@geotechstudio in his video why we calculate predection rata? thank you
@@mansoursoukaina7639 its aassumption to show procedure of the video to perform it.
i will sure do a video on AHP. I need little bit time.
GREAT JOB SIR
Hello, Sir! Can I use SINMAP in the arcGIS 10.2.2?
Sir can u please make video for AHP, method. Thank you
Sure I will

How do you made Rater from Contour, tin and then raster? Can you please share I want to make it

@@geotechstudio one more thing sir , fron where did u get the road map of the area?
th-cam.com/video/oEPcKRj8pds/w-d-xo.html
If we use stream order tool to get stream buffer, will it only count streams or may include other water bodies like canals? Is it a accurate method?

hello sir, where can i get the data of landslides to process in arcGIS??
You have to multiple data sources to create thematic layers
At 9:58 there is an assumption, 500
High value is 1.9 * 10^6 and you can collect and observe the situation of a place as you are familiar to how much flow accumulation can trigger the landslide at that place which becomes threshold value above which landslide getting chance is higher.
@@geotechstudio Thank you.
How do we get the files Band5.tif and Band4.tif? Do we need to create it? If yes, how?
We can get it from downloaded landsat images as it consists of 11 Bands among them only Band 4 and Band 5 are added to calculate NDVI

Any reference or paper related to this?? Plzz....
You can search the keyword landslide susceptibility mapping
Thanks!
I mean about this methodology. If You can share any documents I'll be very thankful.
thank you my freind, i need data for training
We can use landsat images dem , stream and road network as at the time of upload i have saved it as scratch data and lost it. So sry
