Hi Andrea, I sent the whole tree of data, rather than just the raw data. If I check my 0 level tier for pixel size, here's what I get (please excuse the DOS, I do so miss Linux and System 5 Unix)

This is the result I expect when I run gdal_retile. Is this not what the extension expects to see?

Mather ha scritto: > I should say, the file in question is called retile_test1.zip. I looked into this file briefly and found the issue, the files at the lowest level have different pixel resolutions. I can be seen by running on a Linux/Unix command line the following command, which extracts the pixel size from the gdalinfo output on each of the tiff files in the root directory. find . -name "*.tif" -exec gdalinfo {} \; | grep "Pixel Size" The result is: Pixel Size = (0.500000000000000,-0.500000000000000) Pixel Size = (0.500000000000000,-0.500000000000000) Pixel Size = (0.500000000000000,-0.500000000000000) Pixel Size = (0.500000000000000,-0.500000000000000) Pixel Size = (0.500000000000000,-0.500000000000000) Pixel Size = (0.500000000000000,-0.500000000000000) Pixel Size = (0.500000000000000,-0.500000000000000) Pixel Size = (0.500000000000000,-0.500000000000000) Pixel Size = (4.000000000000000,-4.000000000000000) Pixel Size = (8.000000000000000,-8.000000000000000) Pixel Size = (0.500000000000000,-0.500000000000000) Pixel Size = (0.500000000000000,-0.500000000000000) Pixel Size = (0.500000000000000,-0.500000000000000) Pixel Size = (0.500000000000000,-0.500000000000000) Pixel Size = (0.500000000000000,-0.500000000000000) Pixel Size = (0.500000000000000,-0.500000000000000) Pixel Size = (0.500000000000000,-0.500000000000000) Pixel Size = (0.500000000000000,-0.500000000000000) Pixel Size = (0.500000000000000,-0.500000000000000) Pixel Size = (0.500000000000000,-0.500000000000000) Pixel Size = (0.500000000000000,-0.500000000000000) Pixel Size = (2.000000000000000,-2.000000000000000) Pixel Size = (2.000000000000000,-2.000000000000000) Pixel Size = (0.500000000000000,-0.500000000000000) Pixel Size = (0.500000000000000,-0.500000000000000) Pixel Size = (0.500000000000000,-0.500000000000000) Pixel Size = (0.500000000000000,-0.500000000000000) Pixel Size = (16.000000000000000,-16.000000000000000) Pixel Size = (0.500000000000000,-0.500000000000000) Pixel Size = (1.000000000000000,-1.000000000000000) Pixel Size = (1.000000000000000,-1.000000000000000) Pixel Size = (1.000000000000000,-1.000000000000000) Pixel Size = (1.000000000000000,-1.000000000000000) Pixel Size = (1.000000000000000,-1.000000000000000) Pixel Size = (1.000000000000000,-1.000000000000000) Pixel Size = (1.000000000000000,-1.000000000000000) Pixel Size = (1.000000000000000,-1.000000000000000) As you can see there's a hodge podge of different resolutions, I'm not surprised the pyramid plugin is not working. How did you get this mixture? :-) Cheers Andrea -- Andrea Aime OpenGeo - http://opengeo.org Expert service straight from the developers. ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
