Calculate the Timestamp Offset
The time on your camera or data device must match the time in the track or GPS log so the
images or data display in the correct place. If they do not, you must calculate a timestamp
offset. If possible, do this before you use the GeoTagger Wizard.
To Calculate the Timestamp Offset Before Using the Wizard
Use these steps to calculate the timestamp offset before you use the GeoTagger Wizard.
1. Click the Draw tab and view your track or GPS log.
2. Find a point on the track or GPS log where you know you took a picture or recorded
data.
3. Make a note of the time.
4. Start the GeoTagger Wizard and follow the on-screen steps.
5. When you get to the screen with the offset option, highlight the image or data point
in the file list.
The image or data timestamp displays in the Data Timestamp box.
6. Type the time you made a note of in the Matching GPS Time text box.
