Before re-inventing the wheel, I suggest you check to see what is available in existing packages.
Chris Schmidt mentioned in IRC that Mapserv (C based) can cascade and reproject WMS images. I'm not sure about Geoserver or Deegree (java based). I suggest you ask their lists. If you are going to write something, I suggest building upon an existing project as it should: 1. Be easier 2. You will get support and advice from the developers 3. Your code will have a longer lifespan as others will use and extend it Rober Corona wrote: > Thanks!!! > > Now i understand the problem.
