5000x5000 is "small", not worth doing a pyramid, stick with geotiffs with overviews (if they are too big just slice them in a few parts so that they don't become bigtiffs and have GeoServer treat them as a mosaic). > I can´t image having to upload 1300 pyramid stores into geoserver! I've seen deploys with 160000 layers, they appear to be working fine They take quite a bit of time to start up of course, and people organized the data in different workspaces so that they can use virtual services to avoid serving back a caps document with 160000 layer descriptions inside, plus they have an associated OGC catalog to ease search for a layer in the server. That said, these images, are they in some way associated with each other? Like same area different times? Cheers Andrea -- ------------------------------------------------------- Ing.
