GeoComputation 99 Abstracts, Papers, and Presentations

Each half-day session at GeoComputation 99 began with a forty-five minute keynote lecture, which set the overall theme for the session. The keynote lecturers were leading researchers in the field of geocomputation and related disciplines, who were invited by the conference. The keynote lectures were followed by parallel technical sessions with twenty minute presentations by individual researchers. A poster session provided an opportunity for the graphical display of research results.

The conference CD-ROM is available for the cost of shipping and handling. Contact Mr. Bob Abrahart for more information.
