[gdal-dev] How to deal with IIP image via WMS minidriver?

[Carlo A. Bertelli (Charta s.r.l.)]

Dear Petr,
I'm very fond of georeferencer.com; for many topographic and geographic
maps it's more effective than using a desktop application like QGIS.

The idea of implementing IIP/IIIF inside gdal has several reasons.
The first one is due to rights over the images. They are meant for personal
use, sometimes institutions are bound to contracts with private firms that
would not allow them to put these on georeferencer (I'm strongly againt
these agreements, but they are here to stay...), so hosting them elsewhere
would be at least embarassing if not illegitimate (there should also be a
way to open an arbitrary souce besides uploaded images, which is not the
case).
Another one is the ability of comparing historical maps one with another,
which is sometimes useful, besides a comparison between an unreferenced
image and Google Maps/Osm. Sometimes being able to use another reference,
say a cadastral map or a very detailed one is compelling (which is a third
reason).

I think that an alternative way to use IIP/IIIF may be useful and in the
spirit of and Open Source project as gdal.
It's obviously easy to download the tiles one by one (jot/curl) and
assemble them in a sometimes huge file (montage), but a more dynamic way is
a must in these cases. Evan confirmed it would be fairly easy modifying the
WMS mini-driver to do it, but I think a pseudo-referenced (by pixel) VRT
file could be forged (as a temporary provision), knowing the number of
tiles in a row (easy to do) and the number of rows. I'll try to raise some
funding for the project to help in this development. Meanwhile, if someone
would like to try doing something on it, I'll be grateful and I will try to
support this effort even afterwards.
