I see that JOSM can geotag pictures using their timestamp and a GPS track. However my iphone already adds the GPS coordinates to the images. Is it possible to get them into JOSM without having a GPS track? Its for pictures of street signs and such that I use as a reference.
you can open JPG files like other files. JOSM will place icons (default) at the tagged locations. Clicking on an icon shows the picture in a separate window. There you can zoom, shift and go forward or backward from one picture to the other. Don’t hesitate to ask questions in the forum.
