In revision 395 a new module was added for the google map. If you open the map of an image to see the geographic position, surrounding images are shown within map. The new module queries additional images – or markers – via Ajax in the background and add the overlays to the map. Its a pretty nice feature to see a geographic relation of your image.
A screenshot might help to describe the feature or visit the demo page for a live example.
Recently a new input filter for GPS data was added to phTagr. Now, NMEA files from GPS logger such as Sony’s GPSCS1 can be imported directly and adds the GPS coordinates of the images. Combined with Google Maps it adds a nice feature to the gallery to locate your image inside the map.
The GPS coordinates are exported to the EXIF header as GPSLatitude, GPSLatitudeRef, GPSLongitude, GPSLongitudeRef values on the next meta data sync.
While the GPS data are saved in UCT, your timezone of your image might be a different one. The current implementation has a static time offset of two hours (UCT+2), but a special option should be implemented soon. Also an import filter for KML files would be a nice option.
