Wildland Atlas: Offline Topo
Cell service dies five miles past the trailhead. Deep in a granite cirque or under dense redwood canopy, phone GPS drifts and cloud maps go blank. Wildland Atlas keeps you found with zero cell bars, zero accounts, and zero paywalls on your safety.
Built for the High Sierra, coastal redwoods, and Mojave washes, Wildland Atlas turns your iPhone, iPad, iPhone Duo, and Apple Watch into a self-contained field instrument. Every vector contour, water report, land boundary, and botanical specimen lives on your device. Flip on Airplane Mode at the trailhead and navigate with total autonomy.
Your Safety Never Sits Behind a Paywall
Backcountry safety belongs to everyone. Core 2D USGS topographic maps, live GPS positioning, off-trail corridor warnings, and emergency CalFire wildfire and USGS seismic alerts are 100% free forever. You never create an account, surrender an email, or hit a login wall in the dark.
When you want deeper instrumentation, upgrade to Wildland Pro ($4.99/mo or $29.99/yr with a 7-day free trial) or unlock the one-time Sovereign Lifetime Pass ($79.99 with Family Sharing) for 120Hz 3D terrain flythroughs, LiDAR slope shading, and multi-quadrangle offline packs.
Field Instrumentation & Cartographic Systems:
• 100% Offline Flight Architecture
Download crisp USGS 7.5-minute vector contours, shaded relief, and sub-meter satellite orthophotos before leaving pavement. Maps load instantly in wilderness dead zones with zero cellular or satellite signal.
• 15-State Kalman Filter Dead Reckoning
Canyon walls and heavy timber scatter satellite signals. When standard GPS drifts, our 15-state Error-State Kalman Filter (ESKF) and Zero Velocity Updates (ZUPT) fuse inertial step sensors to lock your bearing, stride pace, and sub-meter position.
• 120Hz 3D Mountain Horizon & Demo Walk
Preview every switchback and pass before lacing your boots. Fly along Catmull-Rom trail splines at 120Hz across true-to-scale 3D elevation models with solar ephemeris shadows and smooth camera attitude slerp.
• Alberto Minetti Metabolic Cockpit
Flat miles lie in the mountains. Using Alberto Minetti's 5th-order terrain grade polynomial, the cockpit calculates real-time caloric burn (kcal/hr), mechanical wattage, Naismith transit time, and Equivalent Flat Distance across climbs and descents.
• Live Water Reliability & Vetted 4x4 Scouting
Dry springs end trips early. Check 14-day FarOut water decay scores, spring flow rates, and live USGS CFS stream gauges. Run technical corridors like the Rubicon Trail and Dishpan Springs with obstacle ratings, bypass routes, and 50-inch gate warnings.
• Public Land Cadastral Radar & Statutory Sentinel
Know whose land you stand on across USFS National Forests, BLM tracts, National Parks, State Parks, and private parcels, with California Fish & Game Code § 3004 150-yard safety buffer detection and pet rules.
• Active Wildfire, Smoke & Seismic Sentinel
Track CalFire and WFIGS wildfire perimeters, GOES-18 thermal hotspots, smoke drift vectors, and USGS ShakeMap fault traces alongside mountain SAR radio frequencies.
• On-Device Apple Intelligence & Archival Herbarium
Search trails in plain English or classify trail hazards (blowdowns, flooded fords, rockslides) via on-device Vision and Natural Language. Identify native flora with specimen plates, phenology rings, and 24-hour tidal curves.
• Native iPhone Duo & Apple Watch Companion
Unfold iPhone Duo into Book Mode for an unobstructed 2D map and Tactical Dossier Shelf, or fold into Tabletop Mode for a 120Hz 3D horizon above a touch cockpit. Glance at your Apple Watch for barometric altitude, compass azimuth, and Minetti burn rates.
Zero tracking. Zero analytics SDKs. Zero data sales. Download Wildland Atlas and own the high country.
