NDVI area calculation | Calculate area from pixel | NDVI values range
Ғылым және технология
This video will help to easily classify an image and to calculate the area from it. Creating NDVI and classify the map is so easy. I used Landsat 5 image here. For that, I choose my red band as band number 3 and infrared band as band number 4. You can find the download link for Landsat images and here are some of the videos I have created earlier.

I am glad that you've found it.
Pardon my mistakes. To calculate the square km it have to be divided by 1000 * 1000 = 1000000. I missed one zero.
Really thank you, God bless you
you helped me so muc, thank you

When I categorize and enter values manually, which is better in determining the values.. a value of zero or -1, or we leave the values as they are?
What if the area comes by itself and shape something what do you do. Do you still calculate area
Sir, how do we know the break values for the classify range?
Hi, very helpful video but is this possible to use this area calculation part for calculation of LST area?

Of course you can. As a matter of fact this the procedure to calculate area for pixel. So you can measure any kind of raster image by this process
Asalam Alikum Can you make a video of how can i calculate ndvi by using a very high resolution satellite image
Nice
why should count multiple by 30x30? the count variable is already represent the 30x30 area rite? 30x30 area is counted by 1?

The image resolution is 30 meter. That's why you have to use 30x30. For 10m resolution it will be 10x10.

Each of them has their identification value. You have to put the range in the classify table to make classes. Watch this video carefully you have all YOUR answers here.

Yes, go to properties and symbology. In the classification menu you can find min, max, mean, st deviation. Thanks

@@abirmechkour67 Actually what we have done here is creating and NDVI of our area. NDVI is filled with just numbers from -1 to 1. So, you have to create NDVI and find that file and set your range value.
