Hi all, lately I've been working, under OpenGeo request, to improve the situation vs image pyramids, in particular, making it easier to configure a file based one.
Before the changes you'd had to manually build a mosaic for each level and then also build manually a property file in the root. That is a long and tedious process with many steps in which you can make a mistake. After the change you can basically point the coverage store to a "pyramid shaped" structure (aka, a directory with a set of sub directories, each containing a mosaic of the same area at a different resolution level) and it will do all of the above for you. If the pyramid has been built with gdal_retile it will also take care of reformatting it to the structure the coverage store actually expects. The tutorial is now here and points to data you can use to actually replicate it step by step (assuming you're running from a recent nightly build that is) http://gridlock.openplans.org/geoserver/trunk/doc/en/user/tutorials/index.html The only thing you won't be able to replicate is the layer configuration, where you'll get the wrong layer name due to http://jira.codehaus.org/browse/GEOT-2953 (which I hope will be fixed soon, already provided a patch). Is anyone interested to give the tutorial a spin, a review? Is there anything missing or that could be done better?
