Ciao Simone, actually, like I tried to explain, I don't ever need a map composed of several images. The maximum number is four, if it happens so that e.g. tile is composed of the corners of four maps. We have different maps for different scales so using this particular material is restricted only for accurate zoom levels, it never happens so that I would need a large overview with small pixel number out of tens or hundreds of these maps.
Is mosaic store still the wrong option for this? Pyramid would need more preprocessing, right? - mika - On Mon, 15 Oct 2012 10:48:50 +0200, Simone Giannecchini <[email protected]> wrote: > Ciao Mika, > the ImageMosaic is not the right solution for showing a large number > (> hundreds) of raster at all resolutions levels since when > composing a map at low resolution the plugin would have to load a > small number of pixels from a very large number of images. > > In this case the solutions available vary and you can check these > slides to get some advice: > http://goo.gl/TXJRS > > Basically you can: > - merge the geotiff files into larger ones > - use imagepyramid > > > Regards, > Simone Giannecchini > == > Our support, Your Success!
