GeoMapper Data Collector

GeoMapper Data Collector is application for collecting geographic information in SQLite database and recording GPS tracks with distance and duration measurement. It can be used for various outdoor activities (hiking, running, cycling, ...) with use of offline maps. With control of offline maps transparency, it can be combined either with other offline maps or with Google Maps, if internet connection is available. You can use number of GIS applications (e. g., Global Mapper (manual in Serbian), QGIS) to easily export any map you have and use it as overlay or base map.

• record GeoPoint at current location, specific coordinate or location picked from map
• set user, project and number for every GeoPoint
• predefined set of mountaineering/hiking types for GeoPoint
• export recorded GeoPoints as SQLite database or in other format (CSV, KML, GPX or GeoJSON)
• record GPS track and GeoPoints on it, with basic information about distance and duration
• GPS tracks can be recorded in various formats (GPX, KML or GeoJSON)
• set recording tolerance for accuracy, duration and distance
• import and display on map GPS track files recorded on other devices and apps
• view/use multiple maps as overlays on base map at the same time
• supported formats for offline maps:
    - Google Maps Tiles
    - non-georeferenced images
    - RMaps (.sqlitedb)
    - MBTiles (.mbtiles)
• supported formats for online maps:
    - TMS
    - WMS
• set transparency for every displayed overlay
• place pin on specific coordinates and center map on it function
• display info about current location (coordinates, altitude, speed, accuracy) and recording (start time, duration and distance)
• simple compass
• display coordinates in DMS or DD format
• support for coordinates in MGI/Balkans zone 5/6/7, used on topographic maps in Yugoslavia, using Helmerts transformation
• display coordinates in UTM or MGRS format
• support for using external SD card for storing offline maps
• support for altitude correction, based on Earth Gravitational Model EGM96 and/or NMEA sentences
• logging raw GPS data (NMEA sentences) to file
• detailed list of visible GPS satellites and their characteristics
• notification panel with location coordinates and information about distance and duration (when recording is active), with additional buttons for adding GeoPoint, start/stop track recording and closing notification panel. It can be turned on via Settings->Notification settings tab
• copy, share (via SMS, Viber, eMail, etc.) or save current location (as KML)
