NDVI | Vegetation/Forest Cover Map in ArcGIS

How to NDVI in arcGIS. Hope you will learn easily how to do NDVI for your study area.
NDVI Calculation Equation:
NDVI=(PIR-R)/(PIR+R)
In Landsat 8,
NDVI=(B5-B4)/(B5+B4)
In Landsat 4-7,
NDVI=(B4-B3)/(B4+B3)

[@detectiveconan7722]

Can you make a video of how to collect data for NDVI and NDWI calculation from USGS website

[@detectiveconan7722]

On what basis should we seperate the breaking values

[@bilalawais5723]

Can you share the word file in which you have written all of these

[@idgafdaniyal]

please make a ndvi video on two landsat images

[@ashishkumar2027]

Hello, It is really great work that you are doing, I was just wondering if we can refine it more to get individual species of plant cover ? and what kind of satellite imagery would be required for it

[@karinnaportelaleite7518]

What NDVI formul should used for Sentinel-2 image? And GNDVI for Landsat 5-8 and Sentinel-2? Thanks!!

[@lubchoo]

How did you decide the ranges for shrubs versus other vegetation? Do trees and grass generally have a higher NDVI?

[@HaikalMuhammad1927]

Hey! I am an urban planning student, therefore i use these data as a user. Do you use Radiometric Calibration on each bands' central wavelength? And do you think its necessary or not considering i am an urban planning student and not geodesy student

[@mohdaminkhan7510]

Dear sir, do you used pre-processing data of landsat 8 which u did in qgis. When I try to open the qgis corrected images then the images will not appear and the value of image index exceed no. 1 in both high and low index

[@rekharanisaha3042]

Thanks. Very helpful

[@pacifiqueirenge9673]

My question is, what are the steps to follow when we work on landuse landcover and Space-Temporary Dynamics of vegetation of an area. Finally how to calculate accuracy assessment?

[@user-vo2jg5sk1h]

نعم كأنا الفيديو أكثر من رائع شكرا جزيلا

[@daobuithithuy1880]

Why is the gray level value of my Landsat 8 bands (low - high) after downloading not from 0 like your image but it is a different value from 0? Is your image pre-processed?

[@AshuteTube]

Thank You.

[@susmitasen6975]

Should we need to change the break values ?

[@saniaparveen9428]

Thank you soo much...

[@chewingum1214]

Very nicely explained 👍 can u plz share the band formula for sentinel satellite image?

[@khimsopheak9423]

Dear Sir, I want to calculate the supplemented urban green space to transform the city to be a green one ? How many method could we do this object? Thanks

[@adiletg]

Thank you👍

[@aghiles4017]

thank you

[@The_Backpacker_Botanist]

if my study area had more then 50 LS tiles, then how can I calculate NDVI for so many tiles. is it possible to mosaic them first and then calculate? and if so, then i have to mosaic separately for different bands.?

[@systemtuner4309]

Hellow sir. Sir i have a project of urban saprual cause reduction of mango farms in multan city.i am a student and an average arc gis user.what process i can adopt to plot this issue in map form.will and use land cover technique help in this case.plz help sir

[@thashriftippu]

where to download landsat images and how do i extract agriculture land

[@mohtadiosman3421]

I'd like to ask you is your choices for the 4 values of classification precise?

[@GISRSSolution]

It depends on you or your analysis for study.

[@zoomup6369]

Thanks for the video, i have sample plot each of 25m diameter, and i want to get the ndvi value for this sample plot. how can i access that ndvi value for particular sample plot?

[@bayupratama5388]

Hello are you already got the answer? I currently work on this and still not know how to figure this out

[@khaingyimonlin7124]

how to calculate the threshold value of NDVI

[@bilalawais5723]

where can i get this word document??

[@anneskavanderspoel2698]

Please can you create a video on how to download the Landsat data. There are so many to choose from its not as easy as DEM

[@shivangisaini4240]

Can we clip NDVI data(after creating) only to our study area? or we need to make it seperately? you showed study area later with clipped NDVI. how to do it if i dont want to repeat the whole process but want to clip it only to my study area?

[@GISRSSolution]

Its very simple. You can clip your study area before the operation or after as well. Just go to spatial analyst tool, then Extraction, Extraction by Mask.. You may watch the following video how to extract study area from Image kzbin.info/www/bejne/gH6qp6B6mrxkY5I

[@mdnaimur4948]

Actually I had the same question. And after extraction you need to do the same again.

[@danielelitelabs]

Hello, sorry I am doing the same kind of task however I am getting values between -3.6 to 2.8, different to -1 to 1. Do you think that I am doing something wrong ?

[@aryalin6083]

Same here😅have you figured out how to solve the problem ？

[@danielelitelabs]

@@aryalin6083 What I did was to apply a color classification so, anything below -1 was set as -1 and anything above 1 was 1.

[@sushantkumar2405]

IF my study area comes in two tile then do we need to NDVI separately one each tile and then we need wo mosaic bother tile to extract the study area?

[@GISRSSolution]

First you need to mosaic and then perform NDVI.

[@The_Backpacker_Botanist]

@@GISRSSolution then for each band we need to mosaic separately, or we can composite both bands first and then mosaic?

[@KendalljazzYT]

Why did you not explain what files you added into ArcMap before finding NDVI. That would have been helpful

[@samirss1613]

Landsat 8 image downloaded from may be usgs.

[@vlogwithrokonbhai5086]

great

Please do one video how to calculate NDVI Using NOAA AVHRR Data

[@daobuithithuy1880]

Before calculating the NDVI index, do landsat images need to be calibrated?

[@md.abdullahaziz7822]

How did you get threshold value for waterbody, land ?

[@GISRSSolution]

NDVI values are ranging from -1 to 1. Very low value of NDVI corresponds to barren areas of rock, sand, snow, cloud etc. Moderate values represent shrub and grassland while high value indicates temperate and tropical rainforests. Bare soil is represented with NDVI values which are closest to 0 and water bodies are represented with negative NDVI values. You can classify following the NDVI classes; -1 = Water Body 0 = Bare Soil, Rock, Sand and Snow, Cloud 0.2-0.3 = Shrub and Grassland 0.3-0.5 = Sparse and Unhealthy Forest >0.5 = Dense and Healthy Forest Hope it will help you. Thank you.

[@tobssportshow2831]

[@zannatsima5969]

Thanks for the video. Could you pls make a video of watershed delineation? That would be helpful.

[@GISRSSolution]

I just uploaded Watershed delineation video today. Just go through the link kzbin.info/www/bejne/gHK0h4dqr52Ne9k Also I am in the way of uploading how to calculate Stream density as well. If you find my videos helpful, then please subscribe me to get more cool Tutorials. Thank you 🙂

[@sinthiaoyshe255]

What will be the Formula for Landsat 5? thanks

[@GISRSSolution]

For Landsat 5, NDVI=(B4-B3)/(B4+B3) Subscribe this channel to get more Tutorials. Thank you :)

[@theleaf2215]

Please make one video on Forest Canopy Density (FCD) in ArcGis

[@GISRSSolution]

I'll try. Thanks.

[@phujenda6603]

Why are you choosing float before?

[@GISRSSolution]

Float is not necessary while you calculate. So you can skip that.

[@aartivatsal3453]

which data you are using?

[@GISRSSolution]

Landsat 8 from USGS Earth Explorer

[@Kavya-hg6fl]
