DecaMaps vs GeoNames Map Explorer

Create a large detailed map at once! +++++ features +++++ - DecaMaps is an iPhone and iPad app to create a large detailed map. You can create an original map only by 2 steps. Step1. Decide an area on the map. Step2. Tap the scissor button. The area you choose is quickly drawn a large detailed map. - Easy preview You do not need to zoom in or out to the map. Your iPhone or iPad shows you a large map and a detailed map on the same screen. - Print a large map! You can print out a large poster up to 16 sheets of paper. *Supported paper size: A4/Letter/B4/B5 *Purchase a “large poster print add-on” to print a more than 4 sheets of paper (2 sheets x 2 sheets). (Ad will be removed if you purchase the add-on.) *To print posters, you need a printer that is compatible with AirPrint on the same Wi-Fi network connected with iOS device. - You can also save the map to Camera Roll. Up to 26,000,000 pixel map can be saved as an image file. *On specification of Camera Roll, saved image cannot zoom in enough, but the original image does not become depleted. Save the image to your PC and see it or view with an iPhone app that supports with high resolution image. +++++ "DecaMaps" is useful for +++++ If you print out a large map by yourself, it is very useful for below situations. - Confirm the place where you have never been before. - For pre-confirmation of travel destination or use as a travel guidebook - Print out the places where you have been to or have grown up and enjoy the sight of them - For an evacuation map, an assistant return home map - For a driving map - For check a school route for your child/children - For an event, a lecture presentation

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.
