Question about #OSM building height in #shadowmap and #shademap :

The following two ways are both tagged building=yes and building:levels=<number>, but only for the latter it seems to be reflected in the height of its 3D rendering/the shadow it casts.

https://www.openstreetmap.org/way/243533360
https://www.openstreetmap.org/way/243354595

This is the case both here

https://shademap.app/@34.68114,135.53257,17.5527z,1780128467074t,0b,45p,0m!1780082948418!1780134670510

and here

https://app.shadowmap.org/?lat=34.68081&lng=135.53258&zoom=18.13&azimuth=-0.05190&basemap=map&elevation=nextzen&f=29.0&hud=true&polar=0.52360&time=1780125844403&vq=1

Am I missing something? 🤔

@pixelpfuscher Jetzt, wo du's erwähnst, erinnere ich mich auch daran - und weiß auch nicht mehr, wo das war 😀

Glücklicherweise hilft #OSM Wiki und listet einige #SchattenKarten https://wiki.openstreetmap.org/wiki/Shadows

Schön finde ich #JVeuxDuSoleil https://jveuxdusoleil.fr/#15/50.9398/6.9692

#ShadeMap bietet viele Optionen https://shademap.app/@50.93729,6.95721,15.65844z,1779989121024t,0b,0p,0m,qa8O2bG4=!50.93804!6.96016

#ShadowMap ebenso - allerdings nur gegen Zahlung https://app.shadowmap.org/?lat=50.94130&lng=6.95814&zoom=16.00&azimuth=0.00000&basemap=map&elevation=nextzen&f=29.0&hud=true&polar=0.52360&time=1779957513624&vq=1

Wenn die jetzt noch Routen erstellen könnten ... (*träum*)

Here is an old shadertoy demo I made: Three shadow mapping techniques. Basic, PCF and variance shadow maps :)
Have a look, if you want to see how to implement the base level versions :)

Nice to see screenshots of #Shadowmap https://shadowmap.org/ and #Tropy https://tropy.org/ making the rounds here – the former started as a Master's thesis supervised by me, the latter has two friends of mine as dev and UI leads. 🤗

Good to see friends' projects thrive!
