Then I record the way I walk, with lots of points, and then when I get to the bakery I make a new waypoint called 'BAKERY'. I switch my GPS on at my house, and make a waypoint, called 'HOUSE'. As an example, let's say I walk from my house to the bakery. This is what I wrote in an email to someone asking about the differences:įirstly, it is important to understand the difference between 'track points' and 'waypoints'. The myriad of file formats and strange terminology (routes, tracks, waypoints) might be overwhelming. Some of the terminology used in GpsPrune might be confusing if you're not familiar with using GPSs. What is a waypoint? What is a trackpoint? You may still have a need to use the 'Import using GPSBabel' function for certain file types, however. According to developer answers that's deliberate, and the answer is to not use GPSBabel at all any more - for such GPS receivers the recommendation is to switch the receiver to USB mass storage mode and just use GpsPrune's open file and export gpx functions to access the receiver's storage. With more recent GPS receivers there's a third problem with GPSBabel, in that GPSBabel doesn't support the newer binary communication modes. Note that on some distributions it was okay to say group='plugdev' before, but newer versions of udev only seem to work if it's uppercase GROUP='plugdev'. For more information see gpsbabel's linux page. Again the solution to this appears to be distribution-dependent, but it often involves making a new rule file for udev. There is also a second problem using certain linux distributions, in that the root user is then able to call gpsbabel successfully (using the device ' usb:'), but normal users are not, and just get an error message about a module ''. The exact location of this nf file may depend on your distribution. If it doesn't work, the kernel module has to either be removed (with rmmod garmin_gps) or, better still, blacklisted by an entry in the file /etc/nf using a line like ' blacklist garmin_gps'. Basically there are two main problems - this garmin_gps kernel module may work for some people but doesn't work for many. Sometimes you may get an error message about a module 'garmin_gps' blocking access to the USB device, other times the error message is not so meaningful. It seems like there are (still!) common problems with running GPSBabel under linux, especially with USB Garmin devices. Thanks to Li Zhao for the tip! Using gpsbabel under linux Ln -s /usr/share/fonts/TTF/chinese/ fallback Again using Mandriva as an example, the fonts are installed in /usr/share/fonts/TTF/chinese/ and the java runtime looks for its fonts at /usr/lib/jvm/java-1.6.0-sun-1.6.0.10/jre/lib/fonts/, so to let java find them you need to make a link: cd /usr/lib/jvm/java-1.6.0-sun-1.6.0.10/jre/lib/fonts/ This is platform-dependent, but it may mean adding a shortcut in the java runtime's font directory. The second step is to let java know where to find these fonts.

For example, on Mandriva you have to install an extra package ' fonts-ttf-chinese'.

To get the display working properly, you have to make sure you have Chinese fonts properly installed (just because Firefox displays them properly isn't always enough). It might be that when using the Chinese or Japanese languages, the Chinese characters appear as empty squares instead of the proper characters. And of course you can include these parameters in your shortcut or alias so that you don't have to type them in each time you run GpsPrune. Where of course the proxy host name and port number should correspond to your local settings. To do this, you can set the java runtime's system properties when you launch GpsPrune, like this: java -Dhttp.proxyHost= -Dhttp.proxyPort=80 -jar gpsprune.jar If you do not have a direct connection to the internet, but you have a proxy server, you can use this proxy server to fetch the openstreetmap map tiles for use in GpsPrune.
