What is the best way to geotag photos with data from GPS Tracker Log (GPX format)?
I just returned from a 4 month trip to Southeast Asia. Before I left, I set the time on my camera, a Canon 7D, to match the GPS time on my GPS tracker, a QStarz BT-Q1000X. Both times were set to UTC, also known as GMT.
I have imported the data from the GPS log into Aperture as a GPX file. Now I would like to sync the location metadata on my photos with the data from the GPS log. How can I do this using Aperture 3?
I seem to be having two problems:
- Aperture wants to shift the times based on which part of the track I drag the images onto. Since the camera and gps tracker times were sync'd, I do not want any shift.
- The time shifts that are displayed are 12 hours and a few minutes, rather than 0 hours and a few minutes.
A few additional notes:
- When I imported the GPS track, Aperture automatically changed the time zone of the track to Asia/Ho Chi Minh City, which is correct (GMT+7).
- I have batch changed the images from Camera Time: UTC to Actual Time: GMT+7
- The time on my computer is US/Eastern Daylight Time (GMT-4), or Eastern Standard Time (GMT-5) when the photos where taken.
- Since I was gone for so long, and my GPS tracker memory is limited, I set the tracker to record a trackpoint once every 60 seconds.
Is there a solution to my problems using Aperture 3, or should I start looking for third party applications to geotag the photos before importing them into Aperture?
Thank you.
