Hmm, OK. I've also seen that issue with the flat areas.

When I make a tiled request there are gaps in the contour lines at the tile boundaries (see attached screen shot). I can minimize the problem by added the *buffer *WMS parameter but this only helps with lower zoom levels. When I zoom in on the map the gaps come back because they are now bigger than the buffer size. Is there a way to deal with the buffer size based on the zoom level? Also the documentation mentions automatically computing the buffer value based on the style. This doesn't seem to be happening and my SLD is not using feature attribute values for sizes and does not have external graphics. Could this be because this logic does not work when the Transformation is involved? I am using a 2.2-SNAPSHOT and the SLD is attached.This is one of the known issue with the contour algorithm implemented in jaitools(another one is inability to deal with flat areas).
