So here is finally the data that I needed for my idea: walk directions from A to B while never leaving the shadows, suggesting bars and pubs where to wait while the shadows catch up and let you cross “safely” where before was sunny.
Useful for scorching weather places like south of Spain.
So running directions from B to A while never touching any shade, suggesting churches and rehab centers to ignore while the shadows stay perfectly still?
Currently building something like this for my city. One major challenge I've come across so far is that most APIs will give you coordinates for an address of a place within a building but none of the free, paid or crowdsourced options have reliable information on outside seating polygons. Of course, you could always display the places around you with live shadow data on a map, leaving it up to the user to zoom in and decide based on the satellite image whether the restaurant or café offers outside seating. But to plot the route and then suggest nearby sun/shadow seating options to the user, you would need this information.
You'd need stereo fotos from a low flying plane for this. Several cities are doing this for decades already. I've built such a 3D map for my city like 25 years ago.
Are you referring to the outside seating polygons? Wouldn’t these stereo images still have a lot of noise (trees, cars, trucks, smaller non-building structures) obstructing the target areas?
User with Spanish keyboard here: when I enter 99999 it formats it as 99.999 and when I submit it, it shows as 99, because it uses the dot as decimal separator that is the way we do over here.
Otherwise the UI and concept looks pretty interesting. But until that is fixed, it is unplayable for me.
