Free GPS Software


  • JOpt.SDK
    JOpt.SDK is a tour optimization JAVA library that uses specialized genetic algorithms to calculate an optimized allocation of orders and stops to mobile resources. The algorithm not only provides tours at minimum costs but also considers an arbitrary set of constraints for each tour.

  • TopoFusion
    TopoFusion is a fully featured GPS mapping software package. It maps both USGS (United States Geological Survey) topographical and aerial photo maps for the entire country.

  • GPS Interface
    Interface for NMEA GPS devices based on the WGS84 ellipsoid, with source code.

  • TeleType GPS DEMO
    Works on Windows CE, Pocket PC and Windows 95/98/ME/NT/2000.

  • GPSDrive
    GpsDrive is a car (bike, ship, plane) navigation system. GpsDrive displays your position provided from your NMEA capable GPS receiver on a zoomable map, the map file is autoselected depending of the position and prefered scale.

  • WAYP2shp
    wayp2shp is a simple C-Progam which can read a Waypoint+ file. The data in this file will be converted to the shapefile format which actually means to three files: .shp, .shx and .dbf.

  • GPS3D
    gps3d is a set of utilities that lets you manipulate your GPS from your Linux/Win32 box, and visualize the output in 3D. At the moment, it only supports NMEA capable devices. If you do not own a GPS device, you can still use gps3d to play interactively with a 3D texture mapped model of earth.

  • GPSMan
    GPS Manager (GPSMan) is a graphical manager of GPS data that makes possible the preparation, inspection and edition of GPS data in a friendly environment. GPSMan supports communication with both Garmin and Lowrance receivers.

  • GARNIX
