We are running mapserver connected to a tilecache delivering high resolution orthophoto to a google maps. The problem I am having is that we preprocess all our imagery using reduced resolutions at higher scales and full resolution at lower scales. In the past we have used gdal_merge with - ps 10 10 to merge tile into larger overalls and downsampling the resolution but we have found that the image quality was not adequate. I have been experimenting with gdalwarp using the different resampling methods with varied results. Is there any consensus on which resampling method provided with gdal provide the optimal results (from a viewing perspective) when downsampling imagery data?
