GPS Map Explorer, Advanced screeen shots

If you download tracks from several GPS receivers used at the same time, you will be able to compare the positions from the different units.
By pointing in the time graph, or on the map, you will see an indication of all the GPS receivers at the pointed time. The graphs have time on their x-axis, and other values on the y-axis. The length of the arrows indicates the speed at pointed position/time. The user can relate a certain amount of time to the length



You may view the same information with different levels of details, with or without background maps.


If you see errors in the calibration... (Because the calibration really IS bad, OR because the map is inaccurate)

...you simply choose the calibration tool and drag the track to where you know it belongs on the map. Calibration points are created automatically, and moved/deleted manually.

You may also drag waypoints or simply type a position. The program supports Longitudes/Latitudes and UTM-coordinates.
The default calibration projection uses a "force" method to catch all the calibration positions.

To emphasize the tracks and routes, the user may set the thickness of the lines.



The example files used here may be found on the Examples directory where you install the application. The Doha-map and the track above is a good exercise to learn how to calibrate a map.
