Store description excerpt
LakeMap is the offline chart plotter for Swiss lakes: 22 surveyed lakes with official bathymetry (swisstopo swissBATHY3D) ship inside the app — depth contours, depth shading, seamarks and marinas all work with no connection at all. THE DIFFERENCE: DEPTHS FROM THE LIVE LAKE LEVEL Ordinary charts show depths against a fixed datum. LakeMap computes with the current water level (Swiss federal gauges, FOEN): the depth you see is today's depth — at low autumn levels just as after snowmelt. PREDICTIVE SHALLOW-WATER ALERTS The app projects your course 60 seconds ahead and warns in four tiers before the bottom comes up, with distinct alert tones. Unsurveyed water is treated as a hazard: zones without depth data render violet and raise their own alert tier instead of falsely looking safe. CHART & NAVIGATION • Depth contours and bands from swisstopo swissBATHY3D • Seamarks and buoys, harbours and marinas (OpenStreetMap) • Own position with smoothed course and speed (COG/SOG) • Depth readout under your boat • Automatic lake detection WEATHER & STORM WARNINGS Hourly wind and gust forecast per lake (MeteoSwiss ICON models), cached offline with visible age. Cues at the official Swiss storm-warning thresholds (strong wind from 25 kn, storm from 33 kn) plus official warnings for your lake.
