It is fascinating how someone puts so much effort and time into such a nice piece of software. I'm no programmer myself, but I did work in software testing some time ago, so I will try to help as best as I can.
My picture shows Ping, who likes to show me the way (sitting on a map). Holly (not shown, my Holux M241) later tells me where I actually was. Ping ususally disagrees ...
This is a nice one to share. Wondering where his cat was hanging out when he was away for several days, this guy (Mark Spezio) decided to attach a tracking device to his cat. The IEEE made a nice audio commented photo/video report of it:
Now he isn't using BT747 - if he were he could reduce the side effect of these large spikes on his track. And as far as the device is concerned, I couldn't make out which one he is using. Hints welcome.
GPSLog Labs is another site where you can store your tracks that is well worth a visit. It analyses your track to find positions where you stopped and splits the track in several subsections.
The site is pretty responsive too.
I added this to the list of sites where you can share your tracks.
I discovered an 'open' service that I did not know about yet: Open Route Service. The site demonstrates the route calculation between two positions on the map. I did not test it a lot, but I will likely look into it later.
If you test it more before I do, do not hesitate to leave a comment.
I got a CanMore GT-730F(L) GPS Dongle with Data Logger to have a hands on evaluation of a device with a Skytraq Venus624 GPS inside. I was pretty surprised to find that it did not have a battery allowing it to log positions without USB power. The performance on my desk is not exceptionnal compared to the iBlue 747 A+, but for the moment I blame the design for it - not the chip.
