Hi,<br>I have a huge set of tiffs rasters.<br>Any single tiff is a geotiff tiled (256x256) and as an internal overview.<br><br>To can use this raster dataset to lower scales (full extension) I need to create a single simplified tiff raster of all this dataset.<br>
Now I need to create a single simplified tiff raster .<br><br>I don't know how is the better way to produce this simplified raster.<br>This because the original huge set of rasters are about 2 TB. Every raster is about 15000 x 15000 px.<br>
<br>SO I start creating a catalog named "cat_fogli.vrt" using gdalbuildvrt.<br>And after this was create, I tryed to produce an external overview of this catalog.<br>using this command:<br><br>gdaladdo -r average -ro --config BIGTIFF_OVERVIEW YES cat_fogli.vrt 256 512 1024 2048 4096<br>
<br>Unfortunately gdaladdo seem to be lock. It is take really many time and is always on 0%.<br><br>I don't know if is only a bug time due to the huge size of original raster dataset or I'm using the wrong way.<br>
