Hi Jukka
It is an interesting idea. Thanks!
OSGeo https://www.osgeo.org/ should have had a similar project (U remember
I used their tif files to test the epsg reader in OJ some years ago).
Regarding CRS
a) Geotiff should include also a CRS tag.
b) Non Geitiff. The crs should be included into the .aux.XML sidecar file. (

which works with jpg o PNG in OJ. Not with geotiff as interferes with
statistic dara reader, included into the same file. Not yet solved for OJ
