Ski Resort Trail Map
Interactive 3D ski resort map recreating OpenSkiMap: search any ski area worldwide, view lifts and runs with difficulty colors, 3D terrain with contours, satellite imagery, and live mountain weather.
A from-scratch recreation of OpenSkiMap.org in a single HTML file. MapLibre GL JS draws the mountain in tilted 3D terrain (with a 2D toggle), elevation comes from public Terrarium DEM tiles, and contour lines are generated client-side with maplibre-contour, the same library stack the real site uses.
Search any ski area in the world with autocomplete backed by OpenSkiMap's ski-area dataset and OpenStreetMap's Nominatim geocoder. Selecting a resort pulls its lifts and pistes live from the Overpass API and draws them in the standard difficulty colors (green, blue, red, black, with purple lifts), over a terrain or satellite base layer.
A weather panel fetches the Open-Meteo forecast for the selected mountain: snow, wind, and sun conditions by date and time, plus an avalanche indicator. Like the avalanche forecasting project, this one started with snowboarding: I wanted to understand the trail maps I ride with, then rebuild them.
