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.
