The GPS Map app can turn an Android device into a handy tool for keeping track of locations you’ve already photographed or plan to photograph later. The app allows you to add so-called placemarks to the map, and you can use photos stored on your Android device as markers.
Adding a placemark in GPS Map requires several steps, but ultimately it’s a rather straightforward thing to do. Long-tap on the desired location on the map and tap Yes. Tap then Marker → Import Image. To import an existing photo, tap Gallery (or Browse) and select the desired photo.
If the selected photo contains geographical coordinates, you can attach the photo to the current placemark using the Import Image button, or you can import the photo as a new placemark by tapping on Import Image & Placemark.
Once you’ve attached the photo to the placemark, return to the Placemark Edit screen, modify the default description is necessary and tap the Confirm button to add the placemark. You should then see the placemark with a tiny thumbnail of the attached photo on the map. You can create as many placemarks as you need and use the Settings → Placemarks screen to manage existing placemarks.
GPS Map’s interface is somewhat unpolished, and the app can be slow at times, but if you are looking for a tool that can help you to track locations in an efficient manner, then the app is just the ticket.
