Hi Brian,
I downloaded the sample data and imported to my database and it seems to
work pretty well. I'm using QGIS 1.8, postgis 2.0, postgres 9.1.5, gdal
1.9.1 on ubuntu 12.04.
Sorry for my ignorance but what GDAL version is being released with
linux mint? I couldn't find anywhere online.
The plugin heavily relies on GDAL to perform the visualization so you
need the latest GDAL available to get a decent performance.
From my first tests I can say that GDAL 1.9.1 has greatly improved
performance and the next versions should improve even further. The
fastest visualization that I have achieved with version 1.9.1 is with
single tiled raster files. Unfortunately I wasn't able to get GDAL to
use overviews so far, but Jorge (GDAL's postgis raster developper) is
researching on this subject.
GDAL versions bellow 1.9 should not be able to read postgis 2.0.
Unfortunately, since postgis 2.0 release, the python loader was
discontinued in postgis source. Recently I have started to make the
necessary changes starting from the old code to get it to work. I don't
know if this is going to be a good solution but it seems possible. I'm
trying to avoid the platform-dependent compilation that postgis' raster
loader has in version 2.0 now that it's being entirely written in C. In
the future I should probably release a simple uploader with the plugin,
without all those options until I'm certain that everything is working
according to the standard.
I'm copying this mail to the list to allow other users to find this
thread later.
