My original Wintec WBT-202 got wet and quit. I just purchased a replacement and my previous workflow IS working but it is a time consuming one (with my Canon 5D Mark II) so any suggestions would be appreciated.
1. Sync my camer's time and date with the computer on which the Wintec has been charged. Set out Wintec fully charged and press power switch for it to acquire current location (takes a few minutes).
2. Press the Flag button for 5 seconds. Take first picture to "anchor" subsequent series.
3. Shoot my series of photos while carrying the Wintec.
4. Load my (RAW) images from the FlashCard reader into Houdahgeo
5. Attach the Wintec to my MacBook Air's other USB and press the power button for 5 seconds to put it into MSD mode and so it's icon will mount on my desktop.
6. Click on "Read GPS data from file" and navigate to most recent file and load it.
7. Click on "Write EXIF/XMP/IPTC tags" to add the geo data to the FlashCard (4 above) images. This is a slow process and takes around 10 seconds per image.
8. When that is done, I click on "Export KML" and do it NOT to Wintec (default setting) but to my Desktop where I give it the day's date and save it. (I'm not sure how useful this is.)
9. Now the whole point of all the above is: Open Aperture and import the FlashCard Raw images, now with their geo data and indeed they do import into Aperture with the GPS data.
This workflow works but is time consuming. Also I don't know how to have this work well with Google Earth. Any suggestions would be welcome.
