Flood depths #7

Closed olafveerman closed 4 years ago

Calculate flood depths for each road segment.

olafveerman commented 4 years ago

Notes from conversation with @drewbo :

store flood masks as COGs
Use rio-cogeo for single scene, cogeo-watchbot-light for something scalable
get stats from COG Using something similar to: https://github.com/developmentseed/servir-training-notebooks/blob/master/crop_type_mapping/notebooks/randomforest.ipynb
Look at ~3rd cell. but basically it loops over vectors to get raster data

Quick update.

The data shared with us was structured as a set of shapefiles for 3 different return periods. There is no flood depth information in the layer. The files of the 5 year Return Period had 10m in their name. It's possible that this was a > 10m flood mask, but not 100% sure.
Initial work to process the shapefiles can be found on the branch: feature/flood-cogs

Next step

Xavier is working to get access to flood maps from SBBN/FATHOM with water detphs at 5 – 1000 return periods.

All data is COG'ed and available on s3://rr-data-haiti/floods/cog/

Next step is to work on script that fetches the flood depths by road segment.
