Auto-Carto XI

Proceedings of the International Symposium On Computer-Assisted Cartography

Minneapolis, Minnesota

October 30 - November 1, 1993

Abstract

The Eleventh International Symposium on Computer-Assisted Cartography (Auto-Carto-11) continues the tradition of Auto Carto conferences dating back to the early 1970s. Auto-Carto has become internationally recognized for presenting state-of-the-art papers in digital cartography, the manipulation of spatial data, and geographic information systems. Traditionally,the Auto-Carto conferences have been held every other year and now are held in alternate years from the Spatial Data Handling conferences, sponsored by the IGU. Both of these conferences--Auto-Carto and Spatial Data Handling--focus on basic conceptual/theoretical research. This conference, scheduled at the Minneapolis Hilton from October 30th to November 1st, 1993, is being held directly before GIS/LIS'93. The forty-three papers accepted for publication in this volume were selected from over seventy abstracts submitted to the program committee in April of 1993.
