Gridded3DSet would return you a geometry in VisAD coordinates and you
could then convert those to lat/lon/alt by running them through the
MapProjectionDisplay's coordinate system (fromReference), I would
presume. But tom's point is valid in that you can't always map an
isosurface to a 2D surface. Even a "simple" field like temperature
might have folds where there are inversions.

For example, think of an isosurface of wind speed for, say, the 40kt
isosurface -- they would be "tubes" and "bubbles"...

I'm interested to know if there is a way to extract an isosurface
from a 3d
gridded field and store it as a 2d grid of isosurface heights for
or other purposes, using an IDV Jython script?
Any help is appreciated.
Hi guys - you are probably both aware but just to be sure, the VisAD
class does have methods to extract both isosurfaces and isolines :
NOAA/ESRL/PSD and CU-CIRES
