Analyze floods using ONLY Python! (aka spatial data science)

Analyzing climate change and potential flooding is incredibly important as our world changes, and one way to do this is to use Python and GIS data known as digital elevation models. In this tutorial, we will create a relative elevation model, or model the data relative to the height of a body of water, in this case, the Mississippi River near Cape Girardeau, MO.

0:00 Intro
1:12 What are relative elevation models?
5:42 Downloading USGS data
8:59 Xarray, Rasterio, other libraries, and data prep
11:54 Geocode river using OSMnx
13:53 Create the river elevation model with Xarray and rioxarray
20:09 Visualize with Datashader and wrap-up

This is increadible!! Excellent video format, very well explained. I'm trully in awe of your content, complex information explained simply and summarized. If you are able, please do more videos like this one.

You've done amazing job, Matt. Good luck!

Hi Matt, thank you for this walk through!! I was following along using python in Pycharm and I can't figure out how to see/plot the final images. Any tips?

[odhiambocalvince]

please do a tutorial on how to work with osmnx to perform network analysis

[MrWINI]

Any tips on how to download the initial raster? It is looking for a log in but I can't seem to create one.

Please can you let me know if the OpenCV certification from OpenCV University worths it ? I m actually doing it and invested 1500 cad for my future career in computer vision! Thanks for your feedback!

Thank you so much for this tutorial, i want to learn spatial data science for climate change/ Environmental science. what skill or tools should I learn?

[mojtabakeyvanlu]

That's really interesting and helpful specially when it comes to analysing feasibility studies for large projects. Can you develop it into a QGIS plugin?

[anupalbaruah]

Is it similar to HAND-FIM developed by NOAA-OWP

[ColumbiaBasinJim]

Great! Only I had the same problem at the end. How did you flip the image?

[ajaypatro]

We can use precipitation as weightage it would have been just a boom

Is the flood only based on the morphology of the river? There is no flow data, right? How could the calculation of a specific flow be added?
