GPSylon is a Home & Education software developed by Christof Dallermassl. After our trial and test, the software is proved to be official, secure and free. Here is the official description for GPSylon:
The dinopolis gpstool package is an open source (LGPL) Java GPS application. It consists of different modules that may be used as a programmer's framework or as an application. The main application is GPSylon. A smaller command line tool (demonstration of the gpsinput Library) is named GPSTool. The library that is used to communicate with the gps device can be used independently and is provided as a separate jar file (since version 0.5).
GPSylon is able to show maps downloaded from the expedia map servers. It may connect to a gps device and track your position on the maps. At the moment, it is able to read gpsdata in the NMEA standard from a serial gps device, a file or a gps daemon across a network (available at the gpsd project PaGE).
The main feature is the display of various maps. GPSylon allows the user to navigate around like in a digital Atlas. It shows maps of different scales, so missing maps of one scale do not result in a Black Screen, but show the next larger scale. See the screenshot section for an image.
It allows the download of a single map or for a given location or for multiple maps in a given rectangular area from mapblast or expedia map servers. In the download mouse mode the user may choose a single map or by dragging a rectangle with the mouse, the user may choose to download maps for a larger area. This functionality allows the user to download maps in a given scale for a larger area. Please only download maps you need and be careful not to download thousands of maps, as the map providers will discontinue their service when it is misused!
It uses the open source library openmap for various cartographic things.
Features The following features are implemented. Display different maps from mapblast or expedia server (also for maps of different scale). Display current position (gps position). Read gps data from serial device, file, or gpsd (daemon). you can free download GPSylon 0.5.3 now.
