GPS Logger

Hi,
I think about buying a GPS logger for adding location info to my pictures. Do you have any suggestions for a device which is known to work well with digikam?

Gandalf,
Personally, i use a Tomtom one (Car GPS), where i have added a GPX logger plugin. Work cery with GPSSync kipi-plugin. Of course, the problem of TomTom one is the battery life. It's a GPS dedicaced to be use in a car, not alone. certainly a Sony device is better: http://www.dpreview.com/news/0608/06080202sonygpscs1.asp Note : in the future, when i will port code to KDE4, i will improve the GPSSync kipi-plugin to be able to import KML trace from GoogleMap, like it can do with GPX trace from GPS device.

Hi Gandalf,
some time ago I collected some links in the wiki, http://wiki.kde.org/tiki-index.php?page=Digikam+Geolocalization Personally, I have the DG-100 and am very happy with it, in particular, because it is supported under Linux. (There are smaller devices, but shorter battery life time, some of them only with Bluetooth ...). Note that the Sony (at least the old version, there might be a newer one) does not have a SIRF III chipset, which is considered to be the most sensitive/best currently available (though there are some close competetors. A good mailing list for finding info on GPS devices is gpspassion: http://www.gpspassion.com/forumsen/forum.asp?FORUM_ID=128 Don't hesitate to ask further questions ...

> Hi Gandalf,
> > some time ago I collected some links in the wiki, > http://wiki.kde.org/tiki-index.php?page=Digikam+Geolocalization Thanks a lot for the links, Arnd! This DG-100 seems to be nice to me. In any case, it would be important for me that it is well supported under Linux and digikam in particular. Just to make sure what the workflow would be to synchronize my pictures with the GPS data: - Do I have to convert the NMEA log (no idea about it, but that seems to be what the DG-100 writes) to some other format before I can access them in digikam? I remember having seen something like "open GPX file" in digikam. Or can read digikam this NMEA format, too? - I then open the logfile with all the GPS data and digikam will write the GPS tags in all pictures with corresponding times, right? - One more question: Is it possible to automatically add tags corresponding to the GPS data, like "Location/Asia/Japan/Tokio/Imperial Palace", to the pictures? That would be a great feature saving a lot of tagging time.

I remember having seen something like "open GPX file" in > digikam. Or can read digikam this NMEA format, too? Digikam uses the gpx format. For the DG-100 the above software generates this from the stored track (globalsat was so kind to release the specifications after my request ;-); however the DG-100 does not store the NMEA log (which for example normally contains other useful information, like the number of satellites found and the signal quality, as far as I know). In any case, gpsbabel is able to convert from almost any interesting format to gpx. > - I then open the logfile with all the GPS data and digikam will write the > GPS tags in all pictures with corresponding times, right? Yes. One very important thing: the best is to have the camera time adjusted properly to avoid fiddling around with offsets (which is well supported the GPSync Tool). Something which is helpful is to use `ntpdate` to have a good time on your computer and then compare: date gphoto2 --get-config time date (Sometimes gphoto2 access is instantaneous, sometimes it takes about 7-8s, haven't been able to figure out a scheme here ...) Setting the time in the camera (for models which support this) can be done with gphoto2 --set-config time=.... ((Maybe something like this should be integrated into digikam ... ;-)) > - One more question: Is it possible to automatically add tags > corresponding to the GPS data, like "Location/Asia/Japan/Tokio/Imperial > Palace", to the pictures?

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1 Hi Gandalf, I myself use the Sony GPS CS-1 (old version). Under linux it behaves like a mass storage unit (you can mount it as a vfat file system) and gpsbabel knows how to convert the format to something usable. For myself I use the perl module Image::Exiftool to write the gps data into my images, as this module has write support for raw files too, something I am really missing in digikam, and it allows me to query http://ws.geonames.org for a placename. The latter feature I have submitted as a wish in bugzilla after short conversation with Gilles and maybe the next digikam will have this feature, too - - I regard it as a killer feature for everybody using a gps. Maybe the new version of the Sony GPS is better - at least my version looses track in buildings or heavily shaded areas like big cities. That's the reason why I will wear it attached with velcro on the shoulder part of my camera bag instead of having it dangle from my belt. All in all it's a small, self contained and easy to use device giving good results, so I do recommend it Best regards - Markus -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFHGf88xxUzQSse11ARAkIFAJ4hUF91ISzKk76DbqYQrCf4ow7RUQCePBPC 334I9EXqmCFzhjdIJoiUmno= =mJlf -----END PGP SIGNATURE----- _______________________________________________ Digikam-users mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-users |

In buildings also the DG-100 will usually fail (though sometimes it does not ;-). Whenever the free sight is blocked so that only few satellites are visible for the device, this leads to larger errors. Also, when the device is at rest, there can be quite substantial fluctuations in position. Somehow it seems that for example Garmin devices deal better with such situations (I only compared it once with a track from Garmin GPS Map 60 CSx which has a SirfStar III), but they are a bit more expensive .. Anyway, having geo-referenced images + track is pretty cool to have, and there are many things in this direction which can be done for digikam in the future ...

Just to add: the Sony device is smaller and I like the concept of just attaching it the rucksack. However, I just cam across this tread, where the accuracy is questioned: http://thedambook.com/smf/index.php?PHPSESSID=bce6f2d2210675ddb96cba0e36a6d5ab&topic=2197.0 Anyway, take your time and look what the market offers curently (some for example like the WBT-201), the best is if there are some sample tracks to get an idea (and personally I like to record a data point every second, which allows approx. 11 1/2 hours for the DG-100 ;-) Best, Arnd _______________________________________________ Digikam-users mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-users |

Googling for alternative GPS trackers, I came across the Royaltek devices
RTM-2300 and RTM-3800. For reasonable prices (60-100 EUR) they offer big storage capacity and seemingly excellent accuracy (german test on http://www.skybert.de/navigation/royaltek.htm) however they seem to support no standard protocol for log downloading. Has anybody found information about the usability of these devices under linux?

As an alternative, you can use your mobile phone, and a bluetooth GPS device. Software such as TrekBuddy www.trekbuddy.net can log the GPS position, recording in either GPX or raw NMEA for later processing. Use Bluetooth FTP to get the files from your phone.

Based on this comnment I assume that you use gpsbabel to download the data from the device. I had a go with it, but without any luck. I'm lost in the parameters and options the program needs. On the net I didn't find any further reference. The device is connected to /dev/ttyUSB0. I changed the permission to the device from: crw-rw---- 1 root uucp 188, 0 okt 26 18:08 /dev/ttyUSB0 to: crw-rw-rw- 1 root uucp 188, 0 okt 26 18:08 /dev/ttyUSB0 I tried: gpsbabel -i gpx -f /dev/ttyUSB0 -o gpx -F test.gpx and: gpsbabel -i nmea -f /dev/ttyUSB0 -o gpx -F test.gpx Both didn't work. Arnd, perhaps you can give me your setup i.e. the commandline you use? Furthermore I am curious how you configure the device. Do you use gpsbabel as well? If so, in what way? Thanks for your efforts, Caspar. _______________________________________________ Digikam-users mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-users |

No, this is not my statement; gpsbabel does no support the DG100 (which would be nice BTW....) I use http://sourceforge.net/projects/dg100util/ """ Tool to extract data from a GlobalSat DG-100 GPS data logger and store the data in GPX format. It also can send configuration data to the device, delete stored data and switch the device to GPS-mouse mode.""" If you have any problems with that, you should mail the developer Stefan Kaintoch directly (he is very helpful), and you can put me in CC, if you want. Hope this helps, best wishes, Arnd _______________________________________________ Digikam-users mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-users |

This is true for at least version 1.3.3 (tried it from the SuSE repositories), and for version 1.3.4. as well I suppose. Didn't try it, but the changes log on the website makes no mention of the DG-100. > I use > http://sourceforge.net/projects/dg100util/ > """ Stumbled on this util before, searching the net for a solution. The java-thing scared me off. Nevertheless I gave it a try, but no luck for now. Searched the net some more, and found this weblog, which told me that the cvs-version of gpsbabel supports the DG-100. http://pjvenda.blogspot.com/2007/09/my-new-toy-globalsat-dg-100-gps-data.html So I checked out the cvs-repository of the projects website and compiled it. On the website of gpsbabel you can find some hints. After taken care of the permissions of /dev/ttyUSB0 >sudo chmod 0666 /dev/ttyUSB0 the command >gpsbabel -i dg-100,erase=0 -f /dev/ttyUSB0 -o gpx -F ~/latest-dump.gpx gave me exactly the file as needed by digikam. The thing still to do is making a udev-rule that takes care of the permissions of the device-file when plugging in the DG-100. Arnd, thanks for the time spent. I hope that with this reply I'm of help for you too.

Hi Caspar,
to reply to both of your messages: thanks a lot for finding out that CVS gpsbabel supports the DG-100, this is great news and good to know!

Yes, that's what I did as well - sorry I should have mentioned it, but I completely forgot, because I defined the settings once at some point, and since then I did not change them (and currently I use logging every second anyway. With approx 11 1/2 hours logging time this works out fine for normal trips ...). In principle all the specifications are given at http://www.usglobalsat.com/forum/topic.asp?TOPIC_ID=607 section "2.2 Set Configuration". Maybe you can ask on the gpsbabel list, whether the might even support the setting of parameters for the DG-100. Then only a nice track-editor (splitting and merging of tracks, moving of points) with smoothing of data (i.e. in particular the annoying fluctuations when the device is at rest) is missing ... ;-) Best, Arnd _______________________________________________ Digikam-users mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-users |

But on the other hand in gpsbabel I found an option to insert interpolated trackpoints. So applying a filter option -x interpolate,time=1 is doing the trick as well. > In principle all the specifications are given at > http://www.usglobalsat.com/forum/topic.asp?TOPIC_ID=607 > section "2.2 Set Configuration". > Maybe you can ask on the gpsbabel list, whether the might > even support the setting of parameters for the DG-100. Studying the gpsbabel options didn't give me the impression that with the other deviceformats used, sending configuration options is a possibility. But you never know. Something for my TO DO list, and given time... > Then only a nice track-editor (splitting and merging of tracks, > moving of points) with smoothing of data (i.e. in particular the > annoying fluctuations when the device is at rest) is missing ... > ;-) These all are options with gpsbabel, so it is just a matter of somebody to develop a GUI frontend.
