Credits: who and what helped Windy
The man who started it all is Cameron Beccario who made stunning wind animation winds on Earth. As a kiter and pilot, I liked the project, but I found it useless for serious kite and flight planning. Therefore I have used his open source codes and completely rewrote them.
Vladimir Agafonkin wrote excellent mapping library leaflet. HERE maps and great Czech Mapy.cz provided map tiles. MaxMind is source of free GeoLite2 database. And Open Street Map, RIOT JS, Node JS, GeoNames, Linux, Debian, NOAA, Meteoblue, Josef Sima, Vaclav Blazek, Martin Dolecek and many, many others
