topoXpress vs Trailseek

topoXpress provides the following features: • Multiplatform design: the same software with the same rich functionality for both GIS data collectors and Surveyors on iOS & macOS. • Handling and displaying large spatial datasets (raster and vector). • Responsive and intuitive user interface: easy to learn and use, automatic adjustment to different screen sizes, orientations, and resolutions of mobile (iPhone, iPad) and desktop devices. • Online and offline operation: online data sources (Cloud storage, TMS, WMS, KML), offline raster datasets (jpeg, ecw, ers, tiff, png, lan, bil, ENVI bsq), offline vector datasets (shp, dxf, map, GeoJSON, mif, txt, crd, dat, dbf, tab, mid). • Powerful GIS visualization functions: thematic mapping, transparency, labeling, query, layer groups, vector symbols, line types, fill types, event mapping. • Productive data collection: templates, surveying, stakeout, CoGo (Coordinate Geometry), forms, lists, calculated fields, GIS editing functions, sampling tool, and more. • Collaborative mapping for professional users through the topoXpress cloud service. • Extensive support of GNSS receivers through TCP port & Bluetooth, projection systems, geoids, shift grids. Bluetooth Rangefinder support for CoGo tasks. The app can be used in many different sectors: • Field data collection and inspection • Land Surveying • Topographic mapping • Forestry • Farm mapping • Utility mapping and inspection • Archeology *** NOTE: topoXpress offers all specified GIS functions free of charge. However, loading more than 10.000 records, saving and exporting your job can be done through our cloud service.

The app supports optional background location services, which can may cause a faster battery drain than usual.

Trailseek is an offline GPS app for hiking and backcountry travel. It records your track, marks waypoints, shows where you are on topographic and satellite maps, and points you back to any spot. Your location and data stay on your device. Maps - Free maps with no account: Apple Maps, satellite, hybrid, OpenStreetMap, OpenTopoMap, and USGS Topo. - A 3D terrain option adds relief to the Apple maps. - Download USGS Topo areas and use them with no signal. - Turn on a coordinate grid for latitude and longitude, UTM, or MGRS and USNG. Waypoints - Drop a waypoint at the map center, your location, or a long press. - Set a name, an icon, a color, and a note. - Attach photos from the camera or your library. - Search and sort the list. Tracks - Record distance, time, speed, and elevation. - Elevation comes from the barometer and GPS together. - Recording continues with the screen off. - Review a saved track's stats and elevation profile. Navigation - Follow a compass arrow to a waypoint, with distance, bearing, and ETA. - It uses GPS and the compass, so it works with no signal and no map. Coordinates - Show your position as decimal degrees, degrees decimal minutes, or degrees minutes seconds. - UTM and MGRS/USNG are always there. - Tap a value to copy it. GPX and sharing - Import and export waypoints and tracks as GPX. - Share a waypoint or track as a file, plain coordinates, or a maps link. Drawing - Draw on the map with Apple Pencil on iPad or a finger on iPhone. - Drawings stay fixed to the ground as you pan and zoom, and share between devices. iPad - The map fills the screen and the panels open as popovers. Apple Watch - Record a track, mark and browse waypoints, and navigate from your wrist. - See your track and waypoints on the watch map. - Waypoints and tracks sync with your iPhone. More - A ruler measures distance and bearing between two points. - Sunrise, sunset, moonrise, moonset, and the moon phase for your location. - A trip computer tracks distance, moving time, and average speed. Privacy - No account, no sign-in, no ads, and no tracking. - Your tracks, waypoints, photos, and location stay on your device. Trailseek does not collect them.
