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.

You are welcome

Pardon my mistakes. To calculate the square km it have to be divided by 1000 * 1000 = 1000000. I missed one zero.

Thank you! this is helpful video. i don't know how to calculate the area without using polygon or shape file until i found your video

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?

@aimanshahbudin7368 7 месяцев назад

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

@najibarashid6475 3 года назад

Hi, very helpful video but is this possible to use this area calculation part for calculation of LST area?

@KaziAlmuqtadir 3 года назад

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

@annleticia6171 7 месяцев назад

What if the area comes by itself and shape something what do you do. Do you still calculate area

@cindymaharani5334 3 года назад

why should count multiple by 30x30? the count variable is already represent the 30x30 area rite? 30x30 area is counted by 1?

@KaziAlmuqtadir 3 года назад

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

@KaziAlmuqtadir 3 года назад

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.

@KaziAlmuqtadir 3 года назад

@@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.

@abirmechkour67 3 года назад

Yes i know 't i need to calculate area vegetation and the percentage

@KaziAlmuqtadir 3 года назад

@@abirmechkour67 Honestly I am not very familiar with ENVI interface. I can help you to create NDVI in ENVI. But I can't help you furthermore. Sorry
