YSK that if you are planning an outdoor event, you can check where the shade and shadows will fall on a given day and time

A friend is planning an event this summer and wanted to find a shady spot in a large park for people to sit. I remembered seeing this project, and it helped in my use case

Here is the website: https://shademap.app/

Here is the developer's GitHub with some code, API, and sample projects: https://github.com/ted-piotrowski

Here is an article I found by Bellingcat talking about the features: https://bellingcat.gitbook.io/toolkit/more/all-tools/shademap

There is also this other tool ShadowMap (app.shadowmap.org), but the data quality wasn't great for the places that I tried.
