The pyramid itself does no magic. All the magic is performed by the single mosaic readers that are polled depending on the requeste resolution levels. Therefore the <b>first step</b> is having a mosaic of images like geotiff, tiff, jpeg, or png which is going to be the base for te pyramid. <p> The <b>second step</b> is to build the next (lower resolution) levels for the pyramid. <br> If you look inside the spike dire of the geotools project you will find a (growing) set of tools that can be used for doing processing on coverages. <br> Specifically there is one tool called PyramidBuilder that can be used to build the pyramid level by level. <p> <b>Last step</b> is providing a prj file with the projection of the pyramid (btw all the levels has to be in the same projection) as well as a properties file with this structure: <pre> # #Mon Aug 21 22:23:27 CEST 2006 #name of the coverage Name=ikonos #different resolution levels
