Hi, yes, obviously: the TRIANGULATE command will make more triangles
because it will also fill the land, which I do not want. So, why is my
set of triangles not working in contour ?? That looks like a bug to
me.

And if I try
CONTOUR,Z,X,Y,xstyle=5,ystyle=5, TRIANGULATION=TRI,/CELL_FILL,
MAX_VALUE=10000.

I still get the same error:
% Out of range subscript encountered: <LONG Array[66453]>.
% Execution halted at: $MAIN$
