Hi, I have a GeoTIFF file of 2GB size. Now, this question is about gdaladdo and how to optimize loading time of such a large raster file.
According to my observations QGIS has fastest loading times when it's a single GeoTIFF file with overview images. Q.1: Does anybody have tipps for even faster solutions loading raster files into in QGIS (prepared by OGR or other preprocessors)? The command "gdaladdo -r gauss C:\SG.tif 2 4 8 16 32 64 128 256" takes actually about 7 days on a Lenovo notebook. Q2.: Any hint's on how to accelerate this (or to other tools generating overviews/pyramids)? Yours, S. _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
