Shade-optimized routing paths for pedestrians

This post is the result of a student project. The work was done by the following group of students: Alice Rey, Jihene Haj Hamouda, Yahia Heni, Mohammed El Mehdi Alaoui, Kaies Mhadhbi.

@JauneBaguette
This is how technology should be used 🥹
@dzwiedziu That or burning people who are transforming urban areas into heat sinks… just saying…

@JauneBaguette
They don't use OSM probably, so won't have this feature, and nature will take it's course ^_^J

Also burning is quick, yet not very efficient. Composting would be better. …just saying… ^_^

@JauneBaguette That is excessively cool! Trop fort!
optimising for Granada in summer aye, @AdamBishop ? :)
@nick_attree Exactly this! 😅 💯
@JauneBaguette I've implemented this recently and called it the "Vampire" profile. It uses the OSRM engine and is based on 3D point cloud data (city of Zurich only) and of course OpenStreetMap. It's a prototype, fixed to August, 1st 2024. See https://routing.osm.ch/ > switch to "Foot (Vampire)".

@sfkeller Wow, pretty impressive! Is there any plan to translate the 3D data into a shadiness index?
@JauneBaguette that is so very much needed. I remember when living in Stuttgart that some days in summer that some streets were in extrem sun without the chance of shade.
@JauneBaguette If at all possible it would be amazing to have the street names on top of the route so they're still readable.
