I'm a developer of GDAL PostGIS Raster driver, and I'd like to know if it
would be possible to modify the Add PostGIS Layer menu option to allow
adding PostGIS Raster data, in addition to the PostGIS data.
I don't know how much effort could require to change that dialog to list PG
raster tables as well, but you may add a new option Add PostGIS Raster
Layer with a new dialog.
Opening the QgsPostgresProvider class definition [1], I see it inherits
from QgsVectorDataProvider. I guess I could make the class also inherit
from QgsRasterDataProvider, like GDAL does [2], but as I don't have any
previous experience developing for QGIS core, I'm probably underestimating
the difficulty (besides, I would also need GUI changes...).
You should develop a new provider which extends the QgsRasterDataProvider,
as the current one is for vectors only.
I do have experience developing in C/C++, and developing for GDAL and
PostGIS libraries. So, do you think this could be an affordable task,
without changing a lot of existent code? I'd like this task to be my
August project
It shouldn't be hard too much, but I'm quite sure you must create new
classes and not just change the existent ones.
Anyway, I hope someone who worked on raster stuff can give you any hints,
maybe it's easier than we can tell :)
Regards.
Many thanks in advance.
Best regards,
