Hi: In the process of moving data into GeoTIFF, I am re-creating pyramids (OVR files). The good news: It takes fewer than ten minutes to create an LZW Horizontal Differenced compressed 3.5 GB file on a Windows 7 box using GDAL 1.70+ ( via Tamas Szekeres site; 64-bit precompiled ).
The OVR files are problematic. Using gdal_translate, I can resize by 50% in less than ten minutes. Using gdaladdo, the first layer ( "2" ) takes hours to complete. This is for SRTM 16-bit data. It appears that something is amiss. Tips and tricks? Thanks! = David _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
