Generate Google Earth Map

The MCS software can use recordings of an external GPS logging device to merge with previously recorded measurement values. The result can then be imported into a software like Google Earth to show where measurement values have been taken.

Due to large differences between GPS devices you must manually download the data of your GPS device. When saving the data please make sure you save it in the GPX or NMEA format. If your GPS software does not support that you can try to save it in another format first and use the GPSBabel software to convert it into a GPX file afterwards. Please refer to the GPSBabel documentation for details.

When saving/converting the data also make sure you save the data as „Tracks“. If your software only supports „Routes“ or „Waypoints“ again you can try to use GPSBabel to fix that.

To generate a Google Earth file select the Generate Mapfile menu entry. It will open a dialog where you can select

  •  the GPX or NMEA file with coordinates,
  •  the measurement logfile generated by the MCS,
  •  the output filename for the Google Earth file and
  •  various options to control how the data will look in Google Earth.

The different export options can be used for example to decide if measurements will be displayed graphically as elevation curve, as text labels at GPS waypoints, or both. By default all data will be exported.
After you confirmed the dialog with the OK button the MCS will try to match entries of the GPX/NMEA file with entries of the measurement logfile and display a messagebox stating how many waypoint entries were used for this. If no matches could be found the timestamps in the two files are probably not compatible.

After all dialogs are closed you can open the generated KML file with Google Earth. It should automatically zoom to the recorded track, though you may have to adjust the camera to locate the measurement elevation curve and labels. In the object browser on the left you can enable and disable specific elements (e.g. disable the waypoints to get a clearer view on the elevation profile). The screenshot below shows how the result might look like.

Please note that the information displayed is only a approximation of the real data as there is some interpolation involved in the export process.
