I should have remembered that there is an example on fmepedia - see the ImageShuffler custom transformer.
http://www.fmepedia.com/index.php/ImageShuffler In that example the original raster is tiled and the tiles shuffled about to produce a random output. I don't think that is what you need, but it does show how to use the Tiler to split up the original data. >From there a dataset fanout based on the tile ID would give a separate output file for each tile Regards, Mark --- In [email protected], "mark2atsafe" <[EMAIL PROTECTED]> wrote: > > Hi Sylvain, > Some of the existing transformers will work on both raster or vector > data and the Clipper is one of these.
