Geotagging with iBlue 747

Hi guys,

I recently bought iBlue 747 GPS logger to do OSM mapping. It works great but there’s one issue - I didn’t understand how to figure out the time offset between photo camera and the unit for geotagging purposes (in JOSM). I used to have an old Garmin unit before and just took a photo of the time indicator to calculate that offset, but iBlue 747 has no display and I didn’t find any means to set it’s clock.

What would you recommend to do to solve this? Thanks in advance.

If it has ability to store point at the moment of pushing the button, then just make a photo and bush the button at the same time. After downloading data look for point which was created by button and compare its time with photo time…

Great tip, thanks Jan
