Sorry, what's geo-tagging?

Geotagging of pictures just means to store the (more or less exact) position where the picture was taken as metadata into your pictures. This allows you to do interesting stuff with the help of photo-applications: display your images on a world-map, see where you took the pictures a few years later and so on. Flickr, for example, can show a small map next to the image if your pictures are geo-tagged and you activated the respective option.

The pictures from your WebOS phone camera can be easily geo-tagged automatically by turning on the option in the phone settings. But for (dedicated) photo cameras without a GPS sensor, it's a bit more complicated. This is where "Geotag logger" kicks in.

What is "Geotag logger"?

This application was designed to help with geo-tagging images from an external camera, e.g. your DSLR camera. There are external devices you can buy to track your position and afterwards "merge" the geo-coordinates into your pictures. But since you own a WebOS device with a GPS sensor, you can just use it to log your position with this tiny application. Afterwards you can use Geotag, GPicSync, GPSCorrelate or another existing free and open-source software to include the geo-information from the GPX
file you exported from this application into your pictures. The desktop application matches the time from your position log and your photos, so you should set your WebOS device clock to the correct time as well as your camera clock.

To sum up: Basically this application just tracks your position and provides you a GPX file which you can use to tag your photos with a third-party desktop application.

Tracking

If you just take a few photos here and there, it should be perfectly ok to just hit "Record single trackpoint" before/after you took the photo. If you are moving a lot and take a lot of photos, you should possibly activate "Record continuous". While this mode is active (visible by the spinner in the right edge of the button), the application tracks your position every five minutes. While this might drain your battery a bit more, it's also a lot more convenient since you don't have to remember to track your position every few minutes. Just hit the button a second time to stop the continuous tracking. Be aware that the position might be inaccurate when you activated continuous tracking and you keep your device in a bag or your position doesn't allow accurate tracking, e.g. in buildings.

Export

After tracking your position and shooting a lot of photos, you're back to your desktop computer, editing your photos and you now want to geo-tag them. You just have to export the data stored in your phone by using the application menu. Select "Export GPX" and then select the GPX version. In most of the cases it should be fine to take "GPX v1.1" since it's the current GPX version. Older applications might be picky and just support the older format - so if you get into trouble with the 1.1 version, just try "GPX v1.0". After you get the confirmation that your data was saved, you can attach your WebOS device to your computer. On the USB partition you now find a new folder named "geotag-logger". In this folder you can find all your exported GPX files and copy or move them to your desktop computer.

Clear database

If you exported your tracks and geo-tagged your photos, you should clean up. Just select "Clear database" from the application menu. This empties the tracking database of your application,
but of course it doesn't delete exported GPX files on your USB partition. So you can start with a fresh database the next time you're going out to take photos.

View your tracks on the go

If you want to show your tracks on your WebOS device, you can use the free application GPX Mapper from the App Catalog. Just export a GPX file and then open it with "GPX Mapper". It displays your tracks as a Google Maps overlay.
