Geotag Information Logs
Geotag information for the route the camera traveled is recorded at the
intervals set with [Position update interval] (p.205). The log data is
saved in the camera's internal memory by date. The table below shows
how many days' worth of data can be saved.
Log Data Capacity by Positioning Interval

Every 5 sec.
Every 10 sec.
Every 15 sec.
* Assuming 8 hr. of data logged per day.
The log data saved in the internal memory can be transferred as a
log file to a card (p.212).
One log file is created for each day. The log file name has the date
(YYYYMMDD) and a number, for example, 14103100. If the time
zone changes (p.47), a new log file will be created.
If the camera's internal memory becomes full, the oldest log data will
be overwritten with the newest log data.
Battery Consumption During Logging
When [GPS] is set to [Enable], the camera will continue to receive GPS
signals at set intervals even while the camera's power is switched off.
This will drain the battery faster, reducing the number of shots that can
be taken. Additionally, when [Log GPS position] is set to [Enable],
shorter update intervals will drain the battery more quickly.
When you are not traveling or when GPS signals are weak, setting
[GPS] to [Disable] is recommended.
