The Geo Picture Map App allows you to see pictures you have taken on your last trip or in a particular time span on a map from google play. You can filter the images regarding their capture date or you can pick single pictures directly from local storage.
If the pictures were stored with geo-information (GPS coordinates) from the camera the app shows you the places where there were taken on a map.
Further you can add or edit a GPS-position to your picture by choosing a place on google maps or directly by entering the name of the location. If you change GPS position with the Geo picture app the app stores a backup of the GPS data locally on your device. So you can restore your initially GPS data if you want.
An additional widely used feature of the Geo Picture Map App is the possibility to copy the EXIF data holding the GPS coordinates from one picture to others.
The Picture Map App stores the GPS data within the EXIF tag of the pictures which can be read from other programs or apps too.
If you want to present your last trip to friends you can use the chronological presentation of your pictures on the map.
