- How to NDWI/ Normalize Difference Water Index for your study area.
Normalize Difference Water Index (NDWI) is use for the water bodies analysis. The index uses Green and Near infra-red bands of remote sensing images. Higher NDWI values indicate sufficient moisture, while a low value indicates water stress.
NDWI Formula,
NDWI= (Green-NIR) / (Green+NIR)
For Landsat 8, NDWI= (Band 3-Band 5) / (Band 3+ Band 5)

If you have any queries, feel free to write me in comments section. I'll be happy to help you :)
can i map animal movement in arcmap, using tracking data?
Can you make a video of how to collect data for NDWI and other index calculations
After this operation my values are coming in between -0.46 to 0.16 instead of -1 to 1!? What should I do to resolve this issue?
m so happy to see this man
আপনি একটু ব্যাখ্যা সহ বললে আরও অনেক সুবিধা হত। তবে অনেক উপকার হল।
Good morning. I'm your new subscriber. Pls can you make a video on how to delineate waterlogged areas using Landsat 8 and MNDWI in ArcGIS😭🙏 It's for my final project😢
Why you didn't apply the radiometric correction for images?
How to differentiate between permanent and temporary water bodies? i am working on water logging so i want to know how to calculate those water logged areas only
How did you override the other parts from the shapefile?
i caluculates ndwi in a python script but i got inverted output where nvi positibe ndwi negative its abnormal what could it be ?
For Landsat 8, NDWI= (Band 5-Band 6) / (Band 5+ Band 6)
what is the use of this formula can you explain this is also the formula for calculating NDWI
The formula u mentioned is wrong & It's not for ndwi, it's used for NDBI = (band 6 - band 5)/(band 6 + band 5)
Hello, can I know how much worse I can see the groundwater from the statistical image, please
thank you for this, is there any way you can demostrate to us ndwi using planet data (downloaded as multuband imagery) in arcmap?
How to prepare waterloging map ?
Hi hope you're doing well. My question is when I downloaded the photo I've not chosen which band I want so how did u do it?
You can watch my how to download satellite image and then watch this video. Hope you will understand everything.

Also you can check other videos. Thank you.
Is it possible for landsat 5 and landsat 7 ?
Yes, possible
@@GISRSSolution sir can you share the pdf file of this video and which band is selected for landsat 5 and 7 .?
what will be formula for landsat 4-7
For Landsat 4-7 data, NDWI = (Band 4 - Band 5) / (Band 4 + Band 5)
extract masking is not clear
watch this ruclips.net/video/SiRZCYqV2RY/видео.html
No output
