We present the GeoStar project at RPI, which, motivated by the
large amounts of hi-res data now available, has researched various terrain
(i.e., elevation) representations and operations thereon. GeoStar has the
following accomplishments: - efficient computation of hi-res viewsheds,
- multiple observer (border guard) siting to maximize their joint viewshed,
- (smuggler's) path (motion) planning with a sophisticated cost metric
to avoid that joint viewshed on large terrains, - ODETLAP, an extension
of the Laplacian PDE to an overdetermined system of equations, which is
used in many of the following results, - interpolation from concave and
broken nested contours to surfaces w/o artifacts but with inferred local
maxima, - extremely compact (100x) lossy terrain compression, - terrain
compression that reconstructs slopes accurately, - terrain compression
that maintains hydrological properties, - motion planning on that lossily
compressed terrain, and - interpolation of bathymetry surfaces from very
unevenly spaced ship tracklines.

W. Randolph Franklin is a Professor in the Electrical, Computer,
and Systems Engineering Department, RPI, Franklin's degrees are from Toronto
(BSc, Computer Science), and Harvard (AM & PhD, Mathematica Accomodata).
He served a rotation to the National Science Foundation from January 2000
to August 2002.
At RPI, he is comanager of the Computational Geometry Lab. At NSF, he was
Director of the Numeric, Symbolic, and Geometric Computation Program (later
renamed to Graphics, Symbolic, and Geometric Computing (GSG), in the
Directorate for Computer and Information Sciences and Engineering (CISE),
Computer-Communications Research Division (C-CR). GSG supported research in
computational geometry, computer graphics, numeric computing, mathematical
optimization, symbolic computing, and automated theorem proving. Frankin had
additional responsibility for some panels and proposals in the Information
Technology Research (ITR) and Integrative Graduate Education and Research
Training (IGERT) programs.
