I have an Image Pyramid in GeoServer 2.2 RC3 (not the latests - I know, but I have other pyramids working here).
The total size is around 1TB and file size is around 1-2GB for each GeoTIFF.
When looking at the results using WMS, it all looks blurred. Going into the GeoServer log, I found that when I request an image, it selects the level which I think is causing it to upscale the result to fit the screen:
Size in pixels: 1632x960
Size in meters: 1406x827
I have a GSD = 1 meter/pixel at the level GeoServer selects (which is 3). Shouldn't it select level 2 with a GSD = 0.5 meter/pixel to ensure GeoServer downsamples the result - thus loosing information instead of creating it?
