LakeMap – Swiss Lake Charts

• 11 new lakes: Greifensee, Pfäffikersee, Lake Lugano, Lago di Poschiavo, Lauerzersee and the reservoirs Sihlsee, Lac de la Gruyère, Schiffenensee, Wägitalersee, Wohlensee and Klöntalersee. Their floors come from national-map depth contours (no sonar survey), so they are marked as orientation charts; reservoirs also flag their swinging level, which you set manually. • Lake Lugano gets its live level from the BAFU gauge at Melide. • Perspective view: the compass button now cycles north-up → course-up → tilted 3D view. • Search covers every lake: harbours and services from all installed charts, each with its distance from the boat or the map centre. • Faster first position: the boat shows immediately from the first coarse fix and sharpens as GPS settles. • Smarter opening view: the chart opens on your last position, or on Lake Zurich when you are far from the lakes. • Level and wind chips stay visible within 5 km of a lake, so conditions can be checked from the harbour or the road; between two lakes the nearer shore decides. • Refreshed depth contours for all lakes.

• Restricted areas: speed limits, bathing areas, nature reserves and no-entry zones show as rule chips at the cursor. • Harbour layouts: piers, breakwaters and slipways from OpenStreetMap, so a harbour reads on approach. • Live lake levels now come straight from the BAFU open-data platform (data.bafu.admin.ch), with a fallback feed if it is unavailable. • Shore zones are now part of the chart tiles: sharper and instantly available. • Refreshed charts for Zürichsee, Zugersee, Walensee and Vierwaldstättersee. • Much faster start-up: chart packs are no longer re-copied on every launch and loading runs off the main thread. • Smoother map: level, safety depth and layer changes apply in place without reloading the chart. • Lower battery and memory use: refreshes pause while the app is off screen (unless watch mode is on), depth data loads on demand.
