Contents • • • • • • • • • • • • • • OSM specifics Recording traces General suggestions This device has two options for trace recording - internal memory and microSD card. If recording to the microSD card, traces are written in gpx format, which is suitable for OpenStreetMap usage.
Do not use the device 'Save' feature for tracklogs. Saved tracklogs cannot be uploaded to OpenStreetMap (time information is removed from them). IMPORTANT: deactivate the 'Lock on road' feature before recording tracks. To do so, press menu button from the map view, Setup map, and in the leftmost page set 'Lock On Road' to 'Off'. By default, sampling rate is set to 'Auto' and 'Normal'. This is quite unsatisfactory for OpenStreetMap traces. Here is a comparison of logging at 'Auto/Most often', 1 second and 0.01 km options: • Red - Auto/Most often • Blue - 0.01 km • Green - 1 second As can be seen, even at 'Most often' automatic mode is not satisfactory.
'0.01 km' mode, while mostly producing adequate results, falls a bit short on turns sometimes. '1 second' sampling provides the best results, but, unfortunately, also lots of excess data, especially when not moving. It is thus suggested to choose between '0.01 km' and '1 second' modes. If logging is set to one second, clean up the excess and trash points before uploading the traces. To automatically remove all points that are closer than 2 metres to the previous point: gpsbabel -i gpx -f infile.gpx -x position,distance=2m -o gpx -F outfile.gpx.
All current gpsbabel versions seem to suffer from a data loss bug in position filter () After such an operation it is still suggested to manually clean out 'blobs' of points if having stayed in one location (especially indoors) for some period of time. Saving to microSD card To activate saving to the microSD card, press menu button twice, then navigate to Tracks ->Setup ->Data Card Setup and mark checkbox 'Log Track To Data Card'. Files will be saved with full date being the filename - YYYYMMDD.gpx. To retrieve the files, either insert the microSD card in a card reader, or connect the device to a computer via USB cable and set it to the USB mass storage mode. To do so, press menu button twice, Setup ->Interface and 'click' the 'rocker' button to activate 'USB Mass Storage' option. To return to the normal operation mode, press on/off button once.
Note that the files are saved to the root card directory and there appears to be a limit of 255 files and directories. Once 255 files are written the device will silently stop logging to the card.
Transferring trace from the built-in memory Length is limited to 10 000 data points. In reality this is not so short - 10 000 data points is about 350km of cycling with 'most often' sampling, but see above for trace recording options. With 1 second sampling built-in memory fills up fairly quickly.
To transfer trace from the built-in memory, can be used. Connect the device with a USB cable and issue: gpsbabel -t -i garmin -f /dev/ttyUSB0 -o gpx -F garmin_downloaded.gpx Make sure you have required permissions and use correct USB device. -t stands for 'tracks'. -w can be used for waypoints. Note that this only downloads current log, not the saved ones. Using OSM maps See.to get the OpenStreetMap maps on the device Maps can be created with mkgmap and uploaded to the SD card. Note that map name ( --mapname option) should not exceed 8 characters, otherwise the map will be silently ignored.
