GPS converter

„GPS converter“ makes it possible to convert routes and tracks which are saved in different formats in generally usable formats as *.ovl, *.gpx; *.log, *.kml; *.igc, *.rte, *.plt and *.wpt. For this reason the contents of the files is presented graphically (routes, tracks and points of interest). In the graphic you can choose those elements which shall be converted.

Which formats can be read?

ASCII (text) files with the following endings can be read. In general they were produced with the above-mentioned GPS-programmes:

*.kml - Google Earth
*.ovl - Top50 Overlay by the land surveying authorities
*.gpx - GPS Exchange of EasyGPS
*.txt, *wp - Waypoint +
*.grm, *.trk, *.wpt - Touratech / QuoVadis, GarTrip
*.g7t - G7ToWin
*.igc - SeeYou by Naviter (Navigation-software for flight data)
*.xls - Excel-file of Magellan MapSend
*.plt, *.wpt, *.rte - OziExplorer (Navigation-software for pocket-PC)
*.txt - Fugawi 3 (Navigation-software for pocket-PC)

Input of several files (as well with different formats) one by one is possible as long as they are located spatially. By converting the data are summarized to a GPS file. The contents of the files is shown graphically. In the graphic you can choose those elements (routes, tracks, points of interest) which shall be converted. Afterwards this choice is saved as GPS file in one or several of the following output formats:

Which formats can be output?

The input files can be converted in the following file formats. You can choose one or several file formats for memory. Other file formats can be added on request.

*.ovl - Is for presentation of data on the digital maps of „TOP 50/TOP 200“ of the land surveying authorities.
*.gpx - Is for up- and download of the data (routes, tracks, points of interest) between PC and all common GPS receivers with the freeware EasyGPS and for import into the software „MapSource“ by Garmin.
*.log - Can be used in connection with the software „MapSend“ by Magellan.
*.kml - Can present the data worldwide in the satellite pictures of Google Earth.
*.igc - Can be used in connection with the software „SeeYou“ by Naviter.
*.rte - Is for the import of routes into the software „OziExplorer“ for pocket PCs.
*.plt - Is for the import of the tracks into the software „OziExplorer“ for pocket PCs.
*.wpt - Is for the import of points of interest into the software „OziExplorer“ for pocket PCs.

Tip: Google Earth and the converter

Routes and tracks which are presented in the *.kml-format in Google Earth can be „flown“ in a perspective view. Therefore you have to mark one of the routes in Google Earth in the list “towns” and then click on the “play-button” underneath the list. A further click on this button interrupts the flight. With activated 3D-area-presentation during the “flight” ascents within the routes can be recognized.

If you have not got digital maps for route planning you can use worldwide and free of charge the satellite and aerial pictures of Google Earth. You can “add town marks” in Google Earth which are transmitted as single points of interest and you can “add paths” which are transmitted as routes. For better orientation you can activate parts of towns, streets and street names in Google Earth. Save the town marks and paths as *.kml-file and convert the file with your GPS file converter in one of the above-mentioned output-formats for converting on your GPS receiver.

On the front page of the GPS file converter you can insert the data of the used GPS mobile receiver. You have to distinguish between route, track and waypoint memory. Together with the software "EasyGPS" and the output format *.gpx of this converter you can address these memory terminals one by one. Furthermore you can insert here the maximum number of symbols for the marking of the routes and waypoints. The converter abbreviates automatically and sensibly markings which are too long. Afterwards one or more files can be read in. Directly after the input of the files their contents are presented graphically (see next screenshot).

Graphical presentation of all read in data named as well source file (left screen side). You can now choose those routes, tracks or points of interest which you need by clicking to the specific elements. Only the thus chosen elements are given to the end file (right screen side), direction and name of each element can be changed. The end file is then saved in the above-mentioned output formats. In our example we have a 46 km long track with 726 waypoints which cannot all be transmitted as route to your GPS receiver and which are not all necessary for navigation. Thus routes and tracks can be adapted to the memory capacity of your GPS receiver during converting by deleting all waypoints situated one straight line. The important turning points are kept and are enough for the navigation on the spot. For this purpose the maximum deviation out of the straight line can individually be determined (see next screenshot).

During the converting of routes and tracks all waypoints in one straight line can be deleted. First of all you have to define the maximum deviation out of the straight line. As this is a really abstract term there are three additional details for better orientation. The number of waypoints which are to be deleted, the number of resting waypoints and according to the memory capacity of the used GPS receiver the number of routes/tracks on which the remaining waypoints have to be divided are shown. These details can be calculated either for the route memory or for the track memory. Is one of the fields marked red the memory capacity of your GPS receiver is in this case exceeded, is one of the fields marked green you can transmit the data on your GPS receiver.
