PostGIS Raster driver: overviews found as non regular
|Reported by:||mauriciodev||Owned by:||jorgearevalo|
It seems that the driver is not recognizing the overviews created by the default loader as regular overviews. I've performed a few tests using the python console: In : band=f.GetRasterBand(1) In : band.GetOverviewCount() Out: 0 In : band.HasArbitraryOverviews() Out: True
On this table I created the 2,4,8,16 overviews altogether. I've checked the raster_overviews view in postgresql and there are 4 lines, correctly described as the overviews. I've also been able to read the overview tables in the QGIS plugin by choosing them instead of the base raster. I made my tests using ubuntu 11.10, gdal 1.9, postgis 2.0, qgis 1.7.
Since this is disables the overview reading, the driver's performance is greatly decreased.
