This plugin displays paragliding takeoffs from https://www.paragliding-mapa.cz/, https://www.dhv.de/db3/gelaende/, https://paraglidingearth.com/ and https://www.xcontest.org/ and highlights takeoffs with usable wind direction. Matching wind direction and wind under 4 m/s displays in green, almost matching direction (tolerance ±10°) or wind over 4 m/s in yellow and wrong direction or wind over 8 m/s in red. Other data (such as rain) is not taken into account.
