THANK YOU SO MUCH!
Hello sir I want to ask would u like to help me in research paper making in fuzzy mcdm
Sure
Cleverly done. Thank you for the tip.
Thanks for this. It worked to divide my raster into tiles, but it changes the resolution of the outputs. My input was 30x30 pixels, and the output is 60x60. I'm not sure how to keep the resolution the same as the input
You can try plugin named "Raster Divider". It is easy and effective.
It should not happen. I have used it in many cases. the resolution will be same as of input raster.
Completely helpful. Done successfully. Thank you
love u, saving my time
I have my own sand silt clay data, how to generate from that.
you have to use either interpolation or digital soil mapping approach
@@randomtopicsingiskindly make a video of same.
how will we generate texture map after this

This I have my own data,
Thanks sir for your video
Thanks
Would you mind explaining how did you create point one in the first place

Same result. No label shown brother
if you share a sample file, I can look into it
Thanks!!
Welcome!
How to do new project
Muchas gracias por el apoyo. Saludos cordiales desde México.
thanks so much!
Glad it helped!
Thanks a lot sir😅🎉
hi, can one rotate this grid?
Try affine transform of sf package
Thank you very much for showing the full process in SAGA. This video makes the difference to me
Happy that you find it helpful
Thanks sir...
thank you sir this is exactly what i needed
Good morning sir, I have collected 1500 soil samples from different districts of Manipur State, India. The soil samples were analysed for different forms of soil acidity. Sir I wish to prepare a soil acidity map of Manipur state using my data. Sir Could you share some of your knowledge to prepare.
Sure Mail me at nirmalnbss@gmail.com
@@randomtopicsingis Sir, thank you for considering my request
Good Job. Could you explain satellite image classification using Random Forest method?
will upload a video in few days on image classification using Machine Learning in R
@@randomtopicsingis Very good, you have a great didactics.
What to do?
Combine classes option is not showing
how do i extract LC data from MODIS MCD12Q1 and clip to a study area using terra package

@@lifeiseco7688 plzzz sir give your contact detail I will contact you
Sir Second video Kab aa raha h yaha tk ho gaya 😄
Nice sir
Thanks sir
The best teacher in model building ever! Thank you so much for the simple yet intuitive method of batch clipping! Respect!
Very nice sir..... technically.
Thank you very much
It saved a lot of time and hassle. Thank you sir
Super useful!
Glad you think so!
WEEENA HERMANO MIO ME SALVASTE LA VIDA, ERI UN CRACK
Thanks sir
Welcome
how about if there are multiple rasters at different locations (not overlapping) and you have multiple polygons?
Then do a batch processing
Sir, thank you for this tutorial.
You are most welcome
thanks a lot friend, solved my problem with a large raster file, and its a simple manner to divide a raster and we don´t need a plug in, it is in QGIS tool box.
best and most complete explanation !!
Excellent explanations, Thank You
Thank you so much sir
