![]() ![]() GPS signal reception may take a longer time in some cases.PT Nextome founders: (from left) Giangiuseppe Tateo, Vincenzo. Be careful when sharing these geotagged still images, movies, or GPS log files with others, such as when posting them online where many people can view them. The smartphone tech that guides you inside big buildings Written by Raffaele Mastrolonardo, Contributor Jan. Others may be able to locate or identify you by using location data in your geotagged still images or movies.Be careful about using GPS functions where the operation of electronic devices is restricted.Be particularly careful about using GPS functions outside your home country. Because the use of GPS may be restricted in some countries and regions, follow local laws and regulations where you will use the camera.Note that Canon cannot be held liable for any problems arising from use of GPS functions in other countries and regions. To avoid violating GPS regulations, visit the Canon website to check where use is allowed (). Use of GPS features is restricted in some countries and regions, and illegal use may be punishable under national or local regulations. Be careful when sharing these images with others, as when posting images online where many people can view them.Ĭountries/regions permitting use of GPS functions Others may be able to locate or identify you by using information in your geotagged still photos or movies.Charge the battery as needed, or consider purchasing a spare battery (sold separately). Remaining battery capacity may be lower when GPS features are used.Fewer shots are available in locations with poor signal coverage.Researchers are actively trying to develop indoor GPS tools, but to date, most proposals haven’t gotten past the concept stage. ![]() Also set the correct time zone and daylight saving time for the shooting location. The key takeaway is that GPS relies on a device receiving three or more relatively weak satellite signals, and those signals just can’t penetrate buildings well. Set the camera time and date as accurately as possible.When carrying the camera in a bag or other container, make sure it is face-up with nothing covering it.Although GPS signals can also be acquired with a Speedlite attached, acquisition sensitivity will be slightly lower. Internally, the camera's GPS antenna is near the front of the multi-function shoe.Elevation is not as accurate as latitude or longitude, due to the nature of GPS.The information may also indicate that the camera was used along a route even if it was used at one location. Even in conditions other than these, GPS satellite movement over time may interfere with geotagging and cause missing or inaccurate geotag information.When traveling through different environments.When the camera is carried in a bag or other container.Near high-voltage power lines or mobile phones operating on the 1.5 GHz band.Indoors, underground, near or between buildings, in tunnels or forests.Geotag information may not be recorded or inaccurate information may be recorded where GPS signal coverage is poor, such as in the following places. ![]()
