I'm looking for an Android application (best would be Open Source), that can display georeferenced images on top of a map (Google, OSM, ...).
By Georeferenced I mean that the images four corners are related to world coordinates and a SRS like in GeoTiff or image + worldfile + prj-file. I DO NOT understand a photo + EXIF-Geotag.
A plus would be the possibility to georeference an image.
Edit: I would like to georeference in Android, because I sometimes have unreferenced Plans on my SD-card or find maps out there, take a photo of them, and overlay them with my base map.
