One thing I’ve noticed in my photos is that the GPS location is showing where I was 5 or 10 minutes before I took the photo, which is why I think that the phone only updates periodically, even with Wi-Fi and Cell Service disabled (Airplane Mode).

If you use a smartphone app like GeoTag Photos, is it simply querying the phone’s Location Services (which updates periodically, whatever that period is), or is it querying the built-in GPS receiver in the phone directly to update more frequently? If you use Airplane Mode, you are forcing the phone to use only GPS.Ī related question is: how often does your smartphone “refresh” its GPS location? I don’t know the answer to this, but I’d bet it isn’t very often, as it’s considered a drain on the battery. Smartphones use several ways to determine your location: Wi-Fi network, Cell network, and GPS. One technique I didn’t see here to increase GPS accuracy in your photos taken with a smartphone is to use Airplane Mode.

Sorry to arrive late to the Geotagging Photos discussion! If the area has good Google earth mapping I will adjust the location but if the mapping is poor I will leave it as it is. I find that sometimes the location needs to be adjusted to reflect the actual location of the organism. I recently found a few other applications that can read the RCV-3000 data logger so I’ll experiment with them and see if they can handle RAW files. This isn’t too big a deal as my RAW processor has a goof EXIF editor.

The only shortcoming is that the software does not write the GPS data to RAW files so I have to manually enter the GPS data into my RAW files from the JPEG photos. The EZ-tour software can export a KMZ file. I friend of mine uses Greenwich time all the time on his camera. I no longer bother with daylight saving time and use standard time year round. The camera time drifts by up to a minute a month. For simplicity I always adjust my camera clock every two weeks or so to the second using world time on the computer. The software allows the input of a time zone and time difference from UTM satellite time (the RCV-3000 gets UTM time from the satellites) and the camera. Once the data is uploaded to the EZ-tour software you can add JPEG images from a file or folder and it will write the GPS data to the photos.

I had to find the COM port for the USB through trial and error.

I have not been able to connect via bluetooth and the software manual is not very helpful on bluetooth and the USB connection. I connect the data logger to my computer via the USB port and download the track data. It comes with Holux EZ-tour software for reading the logs. It charges via a USB connection so a battery pack would probably allow for two weeks of daily use. Battery is rated to last 20 hours and I’ve never had a problem. The three lights are for bluetooh, satellite lock and low battery warning. There is only an on and off switch and three lights. It is a very small unit the size of a small box of matches. So last year I purchased a geo data logger Holux RCV-3000 for less than $100 and it’s been great. But it was cumbersome to get the geo data on to my photos, really drew down the battery on the phone so that 4 hours recording was the practical maximum and the last straw was that Google stopped supporting it. It did a good job of tracking my path with an overlay on Google Earth. I used to use a free google app called myTracks on my phone to track my location.
