Hi, Thanks for the reply,
The orthophotos make up a mosaic of my regional planning area . (see Attatchment) Nothing more than a tiled surface. So you are suggesting that I upload 1300 separate files into geoserver? 1300 x 76 mb? (100gb) That alone would take about 2 weeks your wrote.. "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)." Is the Slice Tool a gdal tool? "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" What is a virtual geoserver service?

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.
