Hi Jon, I might be able to help - I've worked with polygon lattices in the past.
What form do the data take ? For instance, variable-sized pixels with corner coords specified or uniform-sized and slanted with centre coords specified... No overlap ? Also, perhaps you could post, or email privately if you prefer, an example of the data. cheers MIchael 2009/1/19 Jon Blower <j.d.blo...@reading.ac.uk>: > Hi all, > > I'm looking for a way of rendering an image of some satellite data. > Each "ground pixel" in the data is represented as a quadrilateral in > lat-lon coordinates, and each pixel is associated with a numerical > value (ozone concentration in this case).
