Prediction Mapping using Frequency Ratio (FR) Model in ArcGIS and Excel only

[@hemanthchandra3186]

Could you please tell me how could I reclassify after getting frequency ratios and create a flood susceptibility map

[@cvt3641]

Thank you for your kind help. Could you please tell me the Function at 6:02 based on which scientific publication or you produce by your self? Thank you again

Hi Van, please find my article as a comprehensive citation source. [ Althuwaynee, Omar F., et al. "A novel ensemble bivariate statistical evidential belief function with knowledge-based analytical hierarchy process and multivariate statistical logistic regression for landslide susceptibility mapping." Catena 114 (2014): 21-36.].

@@ALTHUWAYNEE Thank you sir

[@lckhhl4025]

Hi thank you so much. May I ask why would some of the values of a factor not shown in the table generated by the tabulate area tool? For example, I have reclassified my elevation layer into 10 values, but only values 1 to 5 were shown in the tabulate area table. Was that mean sth was wrong? Or was it just showing there’s no landslide in the elevation values that were not shown?

[@anannyapanging596]

@Hope you got the answer.I am also facing the same problem .Can you please explain me why?

[@jigmetenzin7596]

Is there any tool in QGIS similar to the Tabulate Area tool in ArcMap?

[@zainabkhan2475]

Can you make a video on how to use this method for deforestation assessment...

[@cecilghimire7437]

you said that there are no relationship among independents in bivariate method like Frequency ratio method and again said PR are to consider interrelationship between independents how does these things add up? is it an addiction to frequency addition method can you point me towards further reading??

Hi, how to access the complete video package on the Prediction mapping using ArcGIS and Excel with Modified Frequency Ratio?

[@ALTHUWAYNEE]

Welcome to my course Mathew, I notified that you successfully registered the course, now you have my full guidance support.

[@gunawan342]

how about for landcover change and forecasting?

[@ALTHUWAYNEE]

This is a simple probability based type of calculations, and it can support the stochastic assumptions. Land cover changes deal with temporal data used Markov chain method is more common as well as time series for forecasting.

I am doing with your course in udemy but in QGIS you mentioned only about preparing training and testing data not tabulate area bcz I am facing this problem PLEASE let me know how I tabulate area in QGIS?

[@ALTHUWAYNEE]

Yes Abdul Waseem, This tool is not directly provided in QGIS, and that's why I used ArcGIS in the Frequency ratio course. however, you can do it in multiple steps in QGIS (if you don't have access to ArcGIS). 1- Classify the Variable raster into classes, (like 5 Natural breaks) 2- Convert the Variable into vector polygon 3- Now, you can do like zonal statistics, to find the amount of points in each break. Take all of these information into excel and process it. 4- Multiply the total number of points in each break by area of one pixel (if your data is point based), or multiply by area of one landslide if its polygon based inventory. I hope this will answer your problem. All the best.

[@dehnigeomaticien9698]

hello you should use the tabulate area for each factor as focal statistics and change according to the videos

[@user-et1vz2ru6l]

​@@dehnigeomaticien9698thank you 🤝

[@dr.muhammadafnantalib5941]

Dear can you please make a video on equal to frequency tool in arcgis? I'll be grateful

[@zhoseinzade2081]

Very goodThanks

[@ALTHUWAYNEE]

Thanks for watching!

Hola buenos dias, por suerte tienes un video donde se aprecie el calculo de la curva ROC par aun mapa de susceptibilidad

[@aw869]

thankyou akhee...I have give you full star in your course and I try your suggestion it worked now one question more regarding LULC bcoz in your tutorial you dindt take FR value and put these value as new value in second reclassify of LULC so I also think first reclassification of LULC is sufficient. Am i right?pleas reply akhee and sorry for ask question here
