Hi Nacho, could you clarify exactly what this tool does? I am unclear what is meant by "overviews". A tile is not an overview and why would they need to be resampled?

Hi Wolfgang, gvSIG can build tiles with the option Raster Layer/Overviews. You can choose the number of overviews, ratio and resampling method with the preferences dialog. Depending on the format the process will rewrite the image, be careful. Regards, Nacho El mar, 02-03-2010 a las 08:31 -0800, Wolfgang Qual escribió: > Hi Luis, Jukka, list, > tiled tiff works well.
