Hello Responding on your question Depending on my knowledge, you can't modify a raster by inserting a new column, you have to covert it to a polygon then to reconvert it again to raster after inserting the required informations
So many Thanks!! I have got it very essential. Could you help me how to produce the P-factor values based on agricultural land and other lands classification and slope percent combination? THANKS!
Thank you Sir for your prompt comments. The output from the resultant RUSLE is quite alarming in the sense that the value is 0 - 3323.13 and not 0 - 1 as indicated in your response. I have exclusively followed your procedure on u tube to generate all the factor maps. However, I failed to locate the procedure to compute the final soil loss (i.e A= R*K*LS*C*P). It would really be of immense help, if you could provide us the detail guide lines if you have to generate final RUSLE map and its interpretation.
Tsheten Dorji el salam alaikom my brother No it's not necessary to divide on 100 in the case of the resulted values are between 0 and 1 As you know that the values of the RUSLE factors are between 0 and 1 Take care of yourself el sala
+Hamoutahra Narjisse hello miss how are you doing ? yes you are right it's logical but in my case I used the table which has been developed by wischmeir and smith in 1978 to modelate the P factor using the Slop values you can check that in the thesis of Kenel delusca at the page 91 on this link www.google.dz/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0ahUKEwiX3qyjq8rJAhXBXRQKHc1mBZsQFggaMAA&url=http%3A%2F%2Fwww.collectionscanada.gc.ca%2Fobj%2Fs4%2Ff2%2Fdsk2%2Ftape17%2FPQDD_0009%2FMQ33866.pdf&usg=AFQjCNG2cIhTuOD7MJZIC6RS9p7RJ-QvZg&sig2=z7UyNIldEQJuSL-uGih7OQ&bvm=bv.108538919,d.bGQ&cad=rja

I have one question about p factor.
Why you make the transfer Raster to polygon?
Is it correct to put P factor with slope directly ?

Thank you so much for sharing this amazing video it is very hepfull
You are welcome miss🙂
Thank you for your supportive comments 🙏
Would you please share the data source of P factor table you mentioned as well? It really helps a lot!
❤❤❤❤❤
So many Thanks!! I have got it very essential. Could you help me how to produce the P-factor values based on agricultural land and other lands classification and slope percent combination? THANKS!
Good job. . . .Very interesting
I would appreciate if you could help interpret the final RUSLE map with examples

What criteria that needed to give the c-factor of value?is it has standard value that can be reffered?
It's depends on the type of vegetation
There are a table of standard values of c factors for each vegetation type
@@algeria7002 can you share with me for that table?and what reference/citation that you refer?
@@hazimharun1017 for sure friend
give me your mail?
@@algeria7002 hazimharun95@gmail.com, thank for your helping
@@algeria7002 i'd really like to have it too dude, please. manoa.ranaivosonrapatsalahy@gmail.com
spatial index grid size is invalid comes up after merge is done. does it have any solution?????
Do we have to divide the answer (final RUSLE map) derived after multiplying all the factors together with 100 as in the case of LS factor.

No it's not necessary to divide on 100 in the case of the resulted values are between 0 and 1

plz why u add the number of contouring in pfactor ?? if we don't have any amenagement i think we add to p factor the number 1 !!! plz help me
