Hey, I am faced with a problem I can't solve : I have a raster obtained by using st_setvalues and several points.
The raster has 2 bands, half of the pixel being set. Using the st_pixelaspolygons and the ST_SummaryStats I am sure that some of the pixels of the raster are set. Now when I use gdalinfo or gdal_translate on this in-base raster, it gives the correct information about the raster (size, position, band type, etc), *but the raster has no pixel set!* I tried several combination of parameters with non luck. postgis version : --POSTGIS="2.1.0 r11822" GEOS="3.5.0dev-CAPI-1.9.0 r3963" PROJ="Rel. 4.8.0, 6 March 2012" GDAL="GDAL 1.10.0, released 2013/04/24" LIBXML="2.8.0" RASTER postgres version : 9.3.3 Summary : Raster of 50x50 pixels has 2 bands and extent of BOX(1913.5 20887.5,1914.5 20888.5) band 1 of pixtype 32BSI is in-db with NODATA value of -100000 band 2 of pixtype 32BSI is in-db with NODATA value of -100000 Band 1 contains(histogram, excluding null values): 41660 41666.6666666667 32 0.039360393603936 41666.6666666667 41673.3333333333 0 0 41673.3333333333 41680 0 0 41680 41686.6666666667 656 0.806888068880689 41686.6666666667 41693.3333333333 0 0 41693.3333333333 41700 125 0.153751537515375 gdalinfo : gdalinfo "PG:host=localhost port=5433 dbname='test_pointcloud' user='postgres' password='youguess' schema='test_raster' table='patch_to_raster'" -stats Driver: PostGISRaster/PostGIS Raster driver Files: none associated Size is 50, 50 Coordinate System is: * CORRECT* Origin = (1913.500000000000000,20887.500000000000000) Pixel Size = (0.020000000000000,0.020000000000000) Corner Coordinates: Upper Left ( 1913.500, 20887.500) ( 1d21'30.09"W, 5d51'10.78"S) Lower Left ( 1913.500, 20888.500) ( 1d21'30.09"W, 5d51'10.75"S) Upper Right ( 1914.500, 20887.500) ( 1d21'30.06"W, 5d51'10.78"S) Lower Right ( 1914.500, 20888.500) ( 1d21'30.07"W, 5d51'10.75"S) Center ( 1914.000, 20888.000) ( 1d21'30.08"W, 5d51'10.76"S) Band 1 Block=50x50 Type=Int32, ColorInterp=Undefined Minimum=0.000, Maximum=0.000, Mean=0.000, StdDev=0.000 NoData Value=-100000 Metadata: STATISTICS_MAXIMUM=0 STATISTICS_MEAN=0 STATISTICS_MINIMUM=0 STATISTICS_STDDEV=0 Band 2 Block=50x50 Type=Int32, ColorInterp=Undefined Minimum=0.000, Maximum=0.000, Mean=0.000, StdDev=0.000 NoData Value=-100000 Metadata: STATISTICS_MAXIMUM=0 STATISTICS_MEAN=0 STATISTICS_MINIMUM=0 STATISTICS_STDDEV=0 remi@RemiCura-VirtualUbuntu:/media/sf_E_RemiCura/PROJETS/PC_in_DB/Raster/exported$
