The app can also tell you how far you’ve travelled (15.89km), maximum speed (71.1 km/h), elapsed time (26min) and total elevation (242m), again not information used in geotagging but may be useful just the same for other purposes. You can see on the picture that there’s even an indication of the speed I was doing at each stage, keyed to the legend on the right. While you’re travelling along, you can also use the app to do things like take notes, voice recordings or mark spots with recorded co-ordinates for future reference. Here’s the final trip shown on a Google Map overlay. At random intervals I used the remote to safely take a picture. It’s no Google Map mobile, but it’ll do □ All I needed to do was make sure my phone and camera are synchronised, set the time interval to normal (15 sec), start the GPS on my phone, open the app, start tracking and drive away. My HTC Desire running Open GPS Tracker, Swann Freestyle HD and its remote all “securely” attached via a sticky pad to my dash. So I had to take one of the boys somewhere, so always the opportunist, I set up the above rig. You can see that Open GPS can also make use of Google Maps on your device to display your path live (warning: this may involve data download charges on your device). There’s a plethora of other options as well, but for the purposes of geotagging, it’s really only the logging interval that’s the important one. If there’s no signal for a specified time, an alarm will sound so you know that you’re not logging anymore.
