The International Conference on Interoperating Geographic Information Systems (Santa Barbara December 3-4, 1997) was followed by an invitational Workshop (December 5-6). The conference reviewed the current state of research in related disciplines concerning the technical, semantic, and organizational issues of GIS interoperation; considered case studies of GIS interoperation; and explored theoretical frameworks for interoperation and evaluations of alternative approaches. This document presents the full program of extended abstracts. The conference was part of the Varenius Project's research initiative on Interoperating GIS.
