Hi Jukka. Now that you mentioned it I recall seeing that discussion online.
I'll give it a try. It would be more elegant if vrt format supported several overview levels. Thanks.

Or maybe reference the resampled images in a vrt and have them used as overviews? Hi, Even Rouault helped me when I was experimenting with something like this. You can catch the discussion from here http://permalink.gmane.org/gmane.comp.gis.gdal.devel/31829 The zip file is also still available http://latuviitta.org/documents/GDAL_Scale_dependent_VRT_test.zip This is more fun than doing by hand what gdaladdo normally does because the overviews are not subsampled but they come from totally different data. -Jukka Rahkonen- _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
