Hello,
I'm trying to display Raster postgis data via Qgis (Load Postgis
Raster Layer). It works but it's a bit slow!
These raster are 11 Rapideye satellite images with 5 bands in native. I
defined following overviews for each data : 3,9,27,81,243
Size of smallest SQL file : 270 MO
Size of biggest SQL file : 679 MO
1/What do you think about overviews values ?
2/According to you, the plugin is abble to display a sql file with a
size of 679 MO ?
3/In native, these data have 5 bands but we need display only 3 bands.
According to you, is it better before importing these data in database
to remove 2 useless bands in order to speed up the display ?
4/Is there update regarding the speed problem ( Gdal driver issue).
5/Is there another way faster (Gvsig for instance) in displaying postgis
raster data?
Thank you to throw light for me.
Regards.
Laurent Celati.
