how to calculate NDVI using ArcGis

[@simranaggarwal7437]

Hey!! i couldn't get my values ranging between 1 to -1. Can you please help!?

Thanku for the helpfull and interesting video. I have a question, how about NDVI in ur LST vid? Thats video shows you made NDVI with both of B5 and B4, and in this vid u made NDVI with B3 and B4. Which one were better to calculate NDVI?

[@ahmedaz307]

it depends on the Landsat version..However, you must look for which bands represent red and nir wavelength and then do the calculation. so if they are at B3 and B4 or B4 and B5, the main problem is to know them.

Thanks for your important show about NDVI. Please you had been figure out that NDVI=(PIR-R)/(PIR+R) where PIR is the near infra red band and R is the red band, as known the near infra red band is the band number (B5) where the red band is the band number (B4). With best wishes for you.

thaks sir, PIR= proche infra rouge (francais). I agree, it's true.
