This proceedings of a NATO Advanced Research Workshop (ARW) presents latest interdisciplinary research results on spatial data structures, mapping systems, cartographic feature extraction from imagery, mobile robot navigation, and operational and researchneeds in mapping. The emphasis is on specific techniques for map production and use.
