Hi Markus, It's not entirely clear what you want to do with the pyramids, so on the off chance you want to serve them via a web-map I'll point out that WCS (Web Coverage Service) servers usually include the ability to perform this magic too. deegree does it here: https://wiki.deegree.org/deegreeWiki/RasterTreeBuilder GeoServer here - http://geoserver.org/display/GEOSDOC/Image+Pyramid (the documentation is a little dated in places because they're transitioning documentat systems - asking questions on their excellent mailing list helps)
I imagine the other WCS servers can also do it but I don't know anything about them. In the case of GeoServer, you can have it ouput as a KML layer with WMS (Web Map Service) using the SuperOverlays that Barry mentioned: http://docs.geoserver.org/1.7.x/en/user/google-earth/features/kmlsuperoverlays.html Jonathan 2009/11/23 Markus Loecher <[email protected]> > Dear kml creators, > In "The KML Handbook" (Josie Wernecke), the image pyramid is described as a > very convenient multi-scale view of an image, which elegantly integrates > with kml files. > Unfortunately, no real pointer towards software that performs this task on > a given image file is provided (Figure 5-14 caption: "Search the web for > software tools that can create this image pyramid for you") and a Web search > yielded no real results. > Does anyone have or know about software that partitions an image into > quadtree-like tiles ? > > Thanks in advance, > > Markus > > > _______________________________________________ > Geowanking mailing list > [email protected] > http://geowanking.org/mailman/listinfo/geowanking_geowanking.org > >
