[gdal-dev] New OGR driver: Imageset

 Hi Tamas,

 That would be interesting. So the user could specify a folder with 
 images and GDAL would create an OGR layer that would expose the photo 
 location? The OGR feature would have certain EXIF data exposed as 

 If you work on this, could you also expose other EXIF data, such as the 
 viewpoint coordinates, the image direction, the FOV or focal length, the 
 sensor size, etc. - this information could be used to create a field of 
 view angle of the picture.

 You can try this at http://www.geofoto.ch/geophotomap/index.svg where 
 you can click on a picture standpoint and the browser will display an 
 angle where the picture is looking at.

 I'd be interested in such a provider, as it would open a lot of 
 possibilities to display photo information in various applications.

 Are you aware of EXIFTOOL - the perl-script that allows getting and 
 setting image metadata, such as EXIF, IPTC, XMP, etc.? See 
 http://www.sno.phy.queensu.ca/~phil/exiftool/ - it is sort of the Swiss 
 Army Knife of photo metadata and one of the fewer apps that can also set 
 metadata - not just read.
