TopoWalk

TopoWalk turns your iPhone into a GPS-guided land boundary walker. Load a trail file, walk the boundary, and watch waypoints turn green as you reach each one. WALK ANY BOUNDARY Load land parcels, property boundaries, or hiking trails from GPX, KML, DXF, and Shapefile formats. TopoWalk shows each waypoint on a satellite map with a yellow boundary line connecting them. GPS GUIDANCE Real-time distance to the next waypoint, off-trail warnings, and an audio chime when you arrive within 1 meter of each point. Never miss a boundary corner again. CONVERT BETWEEN FORMATS TopoWalk is the only app that converts between all major surveying and trail file formats. Import a KML cadastral map from a surveyor, convert it to GPX for your hiking app, export as DXF for AutoCAD, or save as Shapefile for GIS software. One tap to convert — no desktop software needed. Supported conversions: • GPX ↔ KML ↔ DXF ↔ Shapefile (SHP) • Import from email, Files app, or any cloud storage • Export and share in any format TRACK YOUR PROGRESS See how many waypoints you've visited, total distance walked, land area and perimeter calculations — all updating live as you walk. 44 WORLD LANDMARKS INCLUDED Explore boundaries of famous landmarks: Buckingham Palace, Taj Mahal, Vatican City, Stonehenge, Machu Picchu, Forbidden City, and many more — all with real satellite-accurate boundaries from OpenStreetMap.
