Saâd, I too got errors. The only way to avoid them for now it to run the individual rasters through their own filter vrt files.
I am going to dig deeper in the ticket #4616. http://trac.osgeo.org/gdal/ticket/4616 On Fri, Apr 13, 2012 at 5:39 PM, Saâd HESSANE <[email protected]>wrote: > Hy list, > > Has anyone reproduce the bug? > > Thank you. > > > > > 2012/4/12 Saâd HESSANE <[email protected]> > >> Yes of course : >> >>> <VRTDataset rasterXSize="52436" rasterYSize="32400"> >>> <SRS>...</SRS> >>> <GeoTransform>...</GeoTransform> >>> <VRTRasterBand dataType="UInt16" band="1"> >>> <NoDataValue>0</NoDataValue> >>> <ColorInterp>Gray</ColorInterp> >>> <KernelFilteredSource> >>> <SourceFilename relativeToVRT="1">1.tif</SourceFilename> >>> <SourceBand>1</SourceBand> >>> <SourceProperties RasterXSize="8449" RasterYSize="6429" >>> DataType="UInt16" BlockXSize="8449" BlockYSize="1" /> >>> <SrcRect xOff="0" yOff="0" xSize="8449" ySize="6429" /> >>> <DstRect xOff="0" yOff="0" xSize="10721" ySize="8158" /> >>> <NODATA>0</NODATA> >>> </KernelFilteredSource> >>> <KernelFilteredSource> >>> <SourceFilename relativeToVRT="1">2.tif</SourceFilename> >>> <SourceBand>1</SourceBand> >>> <SourceProperties RasterXSize="8772" RasterYSize="6407" >>> DataType="UInt16" BlockXSize="8772" BlockYSize="1" /> >>> <SrcRect xOff="0" yOff="0" xSize="8772" ySize="6407" /> >>> <DstRect xOff="43664" yOff="25993" xSize="8772" ySize="6407" /> >>> <NODATA>0</NODATA> >>> </KernelFilteredSource> >>> </VRTRasterBand> >>> </VRTDataset> >> >> >> It's really simple to reproduce the problem : do a "buildvrt" on a set of >> raster ( > 1 raster ).
