NDVI area calculation | Calculate area from pixel | NDVI values range

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.

Sir, how do we know the break values for the classify range?

[uzmabash]

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?
