Working Group II/6 of the International Society for Photogrammetry and Remote Sensing (ISPRS) invites you to participate in a workshop on "3D Geospatial Data Production: Meeting Application Requirements," on April 7-9, 1999. The meeting is organized in cooperation with the Societe Francaise de Photogrammetrie et de Teledetection (SFPT) and the Institut Geographique National (IGN), and will be hosted by the Institute Geographique National in Paris, France. The workshop is organized around 16 selected papers in the areas of cartographic feature extraction (buildings and roads), generation of 3D urban models from non-traditional sources (maps and terrestrial imagery), and commercial systems for automated mapping. Each session will have papers dealing with evaluation methods and metrics for various aspects of automated cartographic data production. In keeping with the workshop atmosphere, three panel sessions are planned in the areas of Research Evaluation, Government Evaluation Requirements, and Research Community Metrics. Nearly an entire day over the three day program is devoted to panels and informal discussions. We believe that this will make the workshop very useful to decision makers as well as research community members. Finally, a tour of the IGN BD-TOPO production facility is planned, as well as a reception at IGN the first evening. Proceedings containing presented papers will be published in the Bulletin of the Societe Francaise de Photogrammetrie et de Teledetection. However, no formal paper or presentations are required for your participation, just a willingness to contribute to the discussions. The workshop program, registration information, hotel information and further details can be obtained from the workshop web page, http://www.ign.fr/sfpt/manifestations/paris_99_us.html, or from the Working Group web page at http://www.cs.cmu.edu/~MAPSLAB/isprs.html. We would very much like to have you join us in Paris for this very topical and timely meeting.
