You are a terrific teacher. I really appreciate that you describe things in plain english as well as technical jargon. I'm studying GIS online through my university and it's caused me so much stress because they just don't make videos like these. Thank you so so much for contributing this to the online community, it's very much appreciated by students everywhere!
Hi, your tutorial is awesome, and it is a real help! Have you got a previous video explaining the primary processing (setting up the boundary around the community)? Thanks Kevin
Thank you for this video! Has helped me a bunch with my MSc. Quick question: How did you change your elevation values from -0.286762 to 35.2728 in your previous video titled Creating a Raster Elevation Map Pt 4 of 4 to the elevation values that you have here (0 to 35)?
Great job. I see you use only DEM data, is there any other methodology? coastline is dynamic and the uncertainty come when you locate wrongly. It differ in low tide than high tide!
Nawaf Almutairi The analyses that I've read in the scholarly literature always use some form of raster analysis with a DEM (i.e. "bath tub model"). LIDAR data is increasingly used. Check out Climate Central's Surging Seas sealevel.climatecentral.org/ and specifically the section on Research to see a the methodology used there.
i guess you need to have an info about the weather and climate to be able to know in specific situation whenever you can considered it 0 m or not because intertidal areas are tricky and changeable
Hi I wanna ask if i wanna analyse flooding of a river, is it the same strategy? Cuz I am not from engineering background so I have no idea about how to analyse flooding
It is likely that the DEM is unprojected - using decimal degrees as the coordinate system. DEMs should be in projected coordinate systems, such as UTM.

Wow thank you so much - you’re a life saver!!! This video has been a fundamental part of completing my masters GIS coursework! THANK YOU!!
This video really helped me on a GIS coursework project for my MSc! Thank you so much :)
Excellent video, It was clear, easy to follow, not to long and very informative. I really learnt a lot
Thank you so much for sharing. This video is so clear and helpful. Really appreciate.
This video is extremely helpful for my university work. Thank you very much, great tutorial :D

Thankyou for this video
Great explanation, thank you for the video.
Really great tutorial! much appreciated...
Are the anomalies the sinks? I learned that rasters should be depression-less to identify potential SLR inundations areas.
Hey, Marcos, how to create the boundary file? Can we use the DEM and set the DEM=0 to derive the boundary file?
Thank you so much for this!!

Thank you Mr
thanks man. It helped me a lot.
I'm sorry, but where do you know the height of affected area is 15 feet? Where to find or calculate that data?
awesome
Why is there less area inundated in 0.425m flood than 0.17m flood when i removed the inland waters? Is that even possible??
Dear, what are the bands of MHElevation and Marblehead if I download data sets from the landsat 8. Thanks
how is the marbelhead boundary made? can you tell me the steps? thank you
What should I do if I want delete area not connected to sea. I need it to show overlay scenarios.
use high resolution coastline data and do a select by location, e.g., select polygons that touch the coastline
Thanks for this. What about intertidal areas that have an elevation above 0m. Would you just classify that area in with 0 mean sea level?
i guess you need to have an info about the weather and climate to be able to know in specific situation whenever you can considered it 0 m or not because intertidal areas are tricky and changeable
thanks!

Don't worry I get it, I missed some step. Thank you
sir how can we check that raster elevation is in feet and we need to convert in to metre??
Did you fill the DEM file before?
Just love it how u explain this thing. And ur english really great for someone doesnt have a high skill on english. Hhahah XD
can we do the same for tsunami
hey, do yu think my 30 m resolution dem is affecting the results of coastal inundation?
It certainly affects greatly. It is considered a critical element when evaluating
Hi ! I need a help. can anyone tell me, how to predict flooded area if water level rise a certain level (suppose rise in 3 meter)? thanks in advance.
unit cell in my DEM is 0.000277. 0.00027 and there isn't unit in linear unit. Do you know why that happened?
It is likely that the DEM is unprojected - using decimal degrees as the coordinate system. DEMs should be in projected coordinate systems, such as UTM.
Where I can find this dataset?
