GPS Logging for Aperture

Hi folks

Does any of you have some experience with Sony DSLR and attachable GPS tracking devices? I have an old Alpha 100 (got it when my Minolta 7D broke...) and would like to know if somebody has tried one of those neat devices which can be attached via the flash socket.

Cheers

Just pull down the small menu by the magnifying glass below the Satellite/Road/Terrain boxes and go to show all. All the images will reappear. What happens is when the images are reassigned they will be sorted, that is why the others disappear! It got me too when it first happened and then I worked it out by clicking around.

Be careful with the Sony CS3... i've seen a lot of terrible reviews about it...

I've ordered the Qstarz BT-Q1000X which has the latest MTKII GPS chip, 42 hours of autonomy with a rechargeable battery... the only problem for me is the memory (lacks of a memory card, it just has its internal memory) which can only record about 40 hours... then you have to download the logs to free the memory (it can be done from a smartphone so that's what i will do)... a lot of people use also the iblue 747 which seems to be pretty good, but has the first generation MTK chip which means less autonomy.

In order to save memory, you can also suppress some datas (altitude and speed for example) and also decrease the frequency of logs (instead of 1 point per second, 1 point every 2 or 5 seconds) since you'll probably be walking when taking pictures in 5 secs you can't walk that much of a distance anyway so the location will still be pretty accurate... if you use 1 point every 5 seconds the device can hold 200 hours of logs.

I'll tell you what i think when i receive and test it.

Cheers.

Successfully used MotionX GPS on my iPhone.

I didn't get the need to drag one of the photos onto the trail. I figured it would just be able to match them up by time.

Wifi triangulation is useless.

Yes.

But only the project I was currently working on.

A gps receiver/logger gets its time from the satellites. There is no more accurate clock to be found.

I use an AMOD AGL3080 logger. It has a mini-USB port and the log files are saved as TXT files with a .log extension, I believe. I then use GPSBabel to convert that log file to whatever format is needed. I con't have a recent track to use with Aperture, but if it will accept a GPX file, this approach will work fine. Costs ~$50 and the download and conversion takes about 15s once you get the hang of it.
