I think the validation with google earth image is not correct in this case, because we have no Idea to which year and date of classified image you have and may be at that particulate date or season data is not available on google earth and you have continuously compared your classified LULC map with current google earth image.
yes my thoughts exactly, time is a key factor but in my case for example i've been able to accurately assess the year of my LULC maps but not the month, which can add a level of inconsistency since agricultural land outside of harvest season may seem like barren land at first glance, but good point!
The main problem is if you want to classify landsat, for example 1973 from where you will get ground truth data? How can you compare and contrast random points to the real location?
Je voulais sortir la matrice de confusion dans argis avec la classification non supervisée. A chaque lancement d'opération, ça sort un message d'erreur. Avec vous une idée ?
I appropriate 🙏🙏but if u can plz I need NDVI.specifically if we have big study area for instance 3 or 4 sentinel 2 image how we can creat NDVI.we do one by one or after mosaic the image?.let me know dear 🙏

I am proud by your ways of presentations
Thanks
Gracias por su amabilidad! Gran video!
Very helpful lesson
thank you sir
Great tutorial thanks
Great video. Good job bro 😎
Very helpful dear..
Kindly update Video on
Area weighted centroid soon as possible.
Thanks
Thank you sir!
You are amazing 👏 🏅thnku sharing fr easy tutorial n finally found

what is the importance of negative signs
I created a supervised classification for 2011 image, then how will I check in google earth and the google earth will show present image
No, you can get the map back from the above option
Sir google earth will show image of present time and how will I get the image for 2011 or say 2001

Sir where is overall accuracy which is most important for Kappa accuracy?
How can I add Segmentation and Classification tool in my Spatial Analyst toolbox?
Did u get this??
Son los mejores
I appropriate 🙏🙏but if u can plz I need NDVI.specifically if we have big study area for instance 3 or 4 sentinel 2 image how we can creat NDVI.we do one by one or after mosaic the image?.let me know dear 🙏
you do one by one before mosaic
Is the data raster or polygon?
Its show error sir.
