Whympr Introduces the Most Detailed Winter Mountain Maps Ever Built for Ski Tourers in the Mont Blanc Massif - SnowBrains

"This winter, Whympr quietly released what it calls the world's most accurate high-definition winter satellite map of the Mont-Blanc massif, built from fresh satellite imagery captured in February 2025. The resolution reaches thirty centimeters per pixel, a level of clarity that allows users to distinguish subtle features like crevasse lines, roller terrain, small ridges, runnels, and even individual ski tracks. In practical terms, that means seeing terrain almost as the eye would from the air-an unprecedented step forward for route planning, hazard assessment, and line visualization."

"Unlike traditional winter satellite layers that often rely on outdated or low-resolution imagery, Whympr commissioned its own targeted satellite acquisition to capture true winter conditions. The result is not just a clearer picture but a more relevant one, showing how terrain actually looks when covered in seasonal snow rather than relying on generic summer basemaps."

""We're a Chamonix-based company focused on building the best all-in-one app to plan outdoor adventures," Tim MacLean wrote in an email correspondence with SnowBrains. "And regarding winter mapping, we've just launched what is, as far as we know, the highest-resolution winter satellite map ever released in an outdoor app."

Whympr, a Chamonix-based platform, released a high-definition winter satellite map of the Mont-Blanc massif using fresh February 2025 imagery at thirty centimeters per pixel. The imagery reveals crevasse lines, roller terrain, small ridges, runnels, and individual ski tracks, enabling aerial-level terrain visualization for route planning, hazard assessment, and line selection. The dataset was acquired via a targeted satellite tasking to capture true winter conditions instead of relying on outdated or generic summer basemaps. The launch focuses on the technically demanding Mont-Blanc region and pairs the imagery with a rebuilt 3D engine, global high-precision terrain, LiDAR where available, and slope angle, aspect, and flat-zone layers.
