[gdal-dev] GDAL adding overviews adds artifacts to the raster

Ariel Zerahia
While trying to add overviews to a raster we observe strange artifacts that did not exists in the original raster.

here is a link to the original raster:


to generate the overviews I used this:

cp one.tif over_one.tif

gdaladdo -r cubic over_one.tif 2 4 8 16 32 64

here you can see the raster with overviews:

by looking at both rasters in low zoom levels you can observe the artifacts.

thanks,
ArielĀ
