<p>Hi,</p>
<p>I also think that there is enough interest by many people/organizations to have support for it in QGIS core.</p>
<p>I would have the following (mostly additional) requirements:</p>
<p><br />1. being able to read a whole folder with photos<br />2. Support for additional graphic file formats next to JPEG. Professional photographers don't store their data in JPEG documents, but in their RAW files(e.g. NEF (Nikon Raw format), CRW (Canon Raw format))<br />3. Support for GPSDestXX Tags to diplay the target point. The target point is in my opinion more important than the point where the photo was taken<br />4. Support for GPSDestBearing/GPSDestDistance to show the direction from the photo standpoint to the target point<br />5. When clicking on a photo it would be nice if the view angle could be visualized, taking into account the fov (field of view) of the lense, GPSDestCoordinates or GPSDestBearing/Distance, based on whatever is available in the EXIF data<br />6. Being able to interactively edit EXIF data in QGIS, esp. GPSDestLongitude/GPSDestLatitude, GPSDestBearing/GPSDestDistance.</p>
<p>See http://www.exif.org/Exif2-2.PDF<strong> </strong>and <a href="http://www.geofoto.ch/geophotomap/">http://www.geofoto.ch/geophotomap/</a> (when you click with the "i" Button on a photo point, the view angle is displayed (see item 5 above))</p>
<p>Paolo: do you have funding for such improvements? I may be able to contribute privately in autumn in a crowd-funding effort (esp. for items 2-6 above)</p>
<p>Perhaps we should first write a complete specification of what we expect from such a tool.</p>
<p>Andreas</p>
