TrekMe - GPS trekking offline 與 GPS Waypoints 使用情況與統計

TrekMe is an Android app to get live position on a map and other useful information, without ever needing an internet connection (except when creating a map). It's ideal for trekking, biking, or any outdoor activity. Your privacy is important as this app has zero tracking. This means you're the only one to know what you do with this app. In this application, you create a map by chosing the area you want to download. Then, your map is available for offline usage (the GPS works even without mobile data). Download from USGS, OpenStreetMap, SwissTopo, IGN (France and Spain) Other topographic map sources will be added. Fluid and doesn't drain the battery Particular attention was given to efficency, low battery usage, and smooth experience. SD card compatible A large map can be quite heavy and may not fit into your internal memory. If you have an SD card, you can use it. Features • Import, record, and share GPX files • Marker support, with optional comments • Real-time visualization of a GPX record, as well as its statistics (distance, elevation, ..) • Orientation, distance, and speed indicators • Measure a distance along a track Some map providers like France IGN require an annual subscription. Premium offers unlock unlimited map downloads and exclusive features such as: • Be alerted when you move away from a track • Fix your maps by downloading missing tiles • Add beacons to alert you when you get close to specific locations ..and more For professionals and enthousiasts If you have an external GPS with bluetooth*, you can connect it to TrekMe and use it instead of the internal GPS of your device. This is especially useful when your activity (aeronautic, professional topography, ..) requires better precision and updating your position at a higher frequency than every second. (*) Supports NMEA over bluetooth Privacy During a GPX recording, the app collects location data even when the app is closed or not in use. However, your location will never be shared with anyone and gpx files are stored locally on your device. General TrekMe guide https://github.com/peterLaurence/TrekMe/blob/master/Readme.md

GPS Waypoints

Multi-purpose mapping and surveying tool for both professional and personal use. The tool is valuable in several professional land-based surveying activities, including agriculture, forest management, infrastructure maintenance (e.g. roads and electrical networks), urban planning & real estate and emergencies mapping. It is also used for personal outdoor activities, such as hiking, running, walking, travelling and geocaching. The application collects Points (such as points of interest) and Paths (sequence of points) to perform mapping and surveying activities. The Points, that are acquired with accuracy information, can be classified by the user with specific tags or characterized with photos. The Paths are created as a temporal sequence of newly acquired Points (e.g. to record a track) or alternatively with existing Points (e.g to create a route). Paths allows to measure distances and, if closed, forms Polygons that allows the determination of areas and perimeters. Both Points and Paths can be exported to a KML, GPX and CSV file and thus be processed externally with a geospatial tool. The application uses the internal GPS receiver from the mobile device (typically with accuracies >3m) or, alternatively, allows professional users attaining better accuracies with a Bluetooth external GNSS receiver compatible with NMEA stream format (e.g. RTK receivers with centimeter level precision). See below some examples of the external receivers supported. The application includes the following features: - Acquire current position with accuracy and navigation information; - Provide details of the active and visible satellites (GPS, GLONASS, GALILEO, BEIDOU and other); - Create Points with accuracy information, classify them with Tags, attach photos and convert coordinates into a human-readable address (reverse geocoding); - Import Points from geographic coordinates (lat, long) or by searching for a street address/point of interest (geocoding); - Create Paths by acquiring sequences of points manually or automatically; - Import Paths from existing Points; - Create survey's themes with custom Tags for classifing Points and Paths - Get directions and distances from current position to Points and Paths using a magnetic or gps compass; - Export Points and Paths to KML and GPX file format; - Share data with other applications (e.g. Dropbox/Google Drive); - Configure positioning source for the internal receiver or using an external receiver. The Premium subscription include the following professional features: - Backup and restore user's data (it also allows transfer data from one handset to another); - Export Waypoints and Paths to CSV file format; - Export Waypoints with photos to KMZ file - Import multiple Points and Paths from CSV and GPX files; - Sort and filter Points and Paths by creation time, name and proximity; - Satellite signal analysis and interferences detection. The Maps feature is an extra paid funcionality that allows selecting and visualizing your Points, Paths and Polygons on Open Street Maps. Additionally to the internal mobile receiver, the current version is known to work with the following external receivers: Bad Elf GNSS Surveyor; Garmin Glo; Navilock BT-821G; Qstarz BT-Q818XT; Trimple R1; ublox F9P. If you successfully tested the application with another external receiver please provide us your feedback as a user or manufacturer in order to extend this list.
