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. Please visit our website for further details: https://topoXpress.com **NOTE ON BATTERY USAGE: The app may dramatically decrease battery life during the use with large spatial datasets. The app supports optional background location services, which can may cause a faster battery drain than usual.

GeoNames Map Explorer turns your iPhone or iPad into an offline-first field GIS for mapping, navigation, data collection, surveying, travel awareness, and team coordination. WORLDWIDE PLACE INTELLIGENCE • Search NGA foreign and USGS domestic geographic names online or from downloaded data • Find addresses, nearby places, map features, U.S. embassies and consulates • Hear supported place-name pronunciations and review weather, travel advisories, emergency contacts, and field references • Translate place information and supported chat content when language tools are enabled POWERFUL ONLINE AND OFFLINE MAPS • Use open MapLibre maps, downloadable areas of interest, and local map packages • Organize online and offline layers, change styles, reorder overlays, and inspect attributes • Work with GeoPackage, MBTiles, GeoJSON, GPX, KML, and other configured GIS sources • Display raster, feature, and vector-tile content with configurable styles and labels • Use MGRS/GARS grids, time zones, boundaries, an inset map, compass, measurement tools, weather, gridded reference graphics, military symbols, placemarks, bookmarks, and geotagged photos • Export map images and manage files through the iOS Files workflow SEARCH, MEASURE, AND ANALYZE • Go directly to a coordinate or convert between common geographic and grid systems • Run offline spatial searches and filter supported attribute tables to the visible map • Find nearby records by map center, typed coordinate, or current location • Convert supported vector GIS data to GeoJSON, GeoPackage features, or MBTiles vector tiles when the DuckDB Spatial build is enabled FIELD DATA AND PROFESSIONAL POSITIONING • Record GPX tracks, waypoints, time, distance, and activity details • Design and complete forms with geometry, attributes, notes, and photos • Create survey sessions, classify points, retain accuracy and GNSS provenance, and export field data • Connect to compatible Bluetooth GNSS receivers • Relay validated NTRIP/CORS corrections to compatible RTK receivers and monitor receiver-reported RTK Fixed, RTK Float, DGPS, and autonomous states TAK AND CONNECTED OPERATIONS • Connect to a configured TAK Server using secure credentials and certificates • Share position information, view team members and map markers, and exchange GeoChat messages • Support Cursor on Target position, chat, marker, and emergency workflows • Connect to supported Meshtastic or Traccar services when those integrations are enabled • Visualize configured real-time feeds for aircraft, vessels, transit, sensors, drones, GeoJSON, KML, and Esri streams AI-ASSISTED, WITH OFFLINE OPTIONS • Import a compatible on-device Gemma model for supported translation and entity extraction • Dictate supported GeoChat messages with Apple speech recognition and listen with text to speech • Extract locations, coordinates, callsigns, dates, routes, urgency, and other structured details from supported messages • Keep TAK text and audio workflows local when the on-device language feature is used PROFESSIONAL AND MISSION WORKFLOWS The solution includes configurable mission planning, tactical graphics, standardized message handling, terrain, training, collaboration, direct GIS service exchange, and cloud-data modules. Availability depends on the release configuration, connected services, organizational authorization, and device capabilities. Some features require downloaded data, an internet connection, a configured server, third-party credentials, a compatible external receiver or radio, or a separately imported AI model. RTK accuracy depends on receiver capability, correction service, conditions, and workflow. This app is a situational-awareness and field-data tool, not a substitute for official emergency, navigation, aviation, maritime, or life-safety systems. Continued background location and Bluetooth use can reduce battery life.
