I am using the following command to load a raster into a postgres database:
raster2pgsql -I -C -e -Y -F -s 3086 -I -C -M myraster.tif myraster -F -t 30x30 | psql -U postgres -d database -h localhost -p 5432
myraster.tif is 155M. When I try to use the raster plugin in QGIS, it takes a very long time to load (15-20 minutes). I'm not sure if there is anything that I can do to speed up this, or if there is an alternative approach to viewing rasters. All I want to be able to do is to quickly view the raster and check that it lines up properly with the vector data stored in the database. (The vector data displays very quickly in contrast.)
At the moment, QGIS freezes up and when it displays the raster. It just shows a black square and changing the colorscale is not feasible due to the fact that any interaction causes the program to freeze.
I'm not familiar with the subtleties associated with loading a raster, so perhaps there are different flags and arguments that I should be using. I realize that this is a large raster so I'm happy to resample it or similar just for display purposes (though I don't know exactly what I should do).
I'm using the latest version of the plugin
wktraster in QGIS. I am connecting to a remote server to display the data. I'm using OSX with QGIS 1.8. I'm open to using any program to view the raster on any OS.
