You cannot download study area shapefiles from USGS. You need to create shapefiles according to your study area. You can download administrative or other type of shapefiles from different websites. We have 2 videos on that on our channel. You can check those videos.
Hi Sir. If I want to just draw the shoreline using the MNDWI layer, I don't need to reclassify the MNDWI and convert it to polygon since I won't use the trace feature to actually draw the shoreline right? Would appreciate your reply sir.
Go to properties of your shapefile or project canvas, go to coordinate system, projected coordinate system, UTM, WGS 1984, Northern Hemisphere, WGS 1984 UTM Zone 44 N
I gathered your first video perfectly. Thank you sooo much❤❤❤❤❤ love from Bangladesh
Thank you ❤❤
I appreciate the in depth video. Very well explained, cheers from a master's student from Federal University of Brazil
Thank you for your comment. love from India.
Can't wait for the Second part, sir. Your videos are awesome
Thank You
Hi sir, I'm a beginner.
Could you please explain how you downloaded the shape file for your study area from USGS.

are you using landsat8 imaginaries??
Yes
thank you, brother, if you don't mind can i get your mail address
@@thavaneethanthangavel5557 You can find it in our channel's about section
sir can you please tell how you have extracted the puri shapefile?
Go to Survey of India website & download Indian District Shapefile (ADM_2) then select puri district and extract your particular district shapefile
@@dawnofgeospatialworld thank you sir
Sir, do I have to transfer the image into projected co-ordinate system utm before calculating the mndwi?
Yes, always work with UTM projection

Yes, You can draw shoreline on MNDWI Layer
Coastal vulnerability index please map
We will try to make a tutorial on it
sir, why are we using MNDWI instead of ndwi? what is the formula for the MNDWI for landsat 7 and landsat 5?
MNDWI is the modified formula for NDWI. you can use NDWI for this work but MNDWI will be more precise.
For Landsat 5 & 7 the formula is
(Band 2 - Band 5) / (Band 2 + Band 5)
(Green - SWIR1) / (Green + SWIR1)
hello when I am sketching the shoreline shapefile there are too many broken lines like broken glasses how to trace them ?? I am a bit confused
I think i have given the answer to you in Facebook?
How do I get the WGS 1984 UTM Zone 44N coordinate system sir?
Go to properties of your shapefile or project canvas, go to coordinate system, projected coordinate system, UTM, WGS 1984, Northern Hemisphere, WGS 1984 UTM Zone 44 N
Actually puri comes under 45N zone...but you explain well.@@dawnofgeospatialworld
Below 0 value should be land, that is correct?
Yes, Below 0 was land. Sorry for that mistake
