Cloudbase Predictor helps paragliding, hang-gliding, and sailplane pilots assess flying conditions for a selected location.
It visualises atmospheric forecast soundings from Open-Meteo with thermic forecasts, wind profiles, Stuve diagrams, and cloud-cover charts. You can pick a point on an OpenStreetMap-based map, browse ParaglidingEarth launch sites, save favourite flying sites, choose whether Favorites opens on startup, compare forecast models, and use dark mode in the field.
Forecast data is provided by Open-Meteo. Launch site data is provided by ParaglidingEarth and can be disabled in Settings. Map layers are provided by OpenFreeMap, OpenTopoMap, NASA GIBS, Esri World Imagery, OpenMapTiles, OpenStreetMap contributors, and SRTM.
Anti-Features: NonFreeNet (this application promotes/depends a non-Free network service):
⇒ The optional Esri World Imagery map layer uses Esri's proprietary hosted imagery service.TetheredNet (This app is bound to a certain network service):
⇒ Forecasts use the fixed Open-Meteo API endpoint. Launch sites use the fixed ParaglidingEarth API endpoint. Bundled map layers use fixed hosted services from OpenFreeMap, OpenTopoMap, NASA GIBS, and Esri World Imagery. Users can choose between bundled map layers and can disable launch sites, but cannot configure alternate service instances.
