  abstract =	 {We propose a factored approach to mobile robot
                  map-building that handles qualitatively different
                  types of uncertainty by combining the strengths of
                  topological and metrical approaches. Our framework
                  is based on a computational model of the human
                  cognitive map; thus it allows robust navigation and
                  communication within several different spatial
                  ontologies. This paper focuses exclusively on the
                  issue of map-building using the framework. \par Our
                  approach factors the mapping problem into natural
                  sub-goals: building a metrical representation for
                  local small-scale spaces; finding a topological map
                  that represents the qualitative structure of
                  large-scale space; and (when necessary) constructing
                  a metrical representation for large-scale space
                  using the skeleton provided by the topological
                  map. We describe how to abstract a symbolic
                  description of the robot's immediate surround from
                  local metrical models, how to combine these local
                  symbolic models in order to build global symbolic
                  models, and how to create a globally consistent
                  metrical map from a topological skeleton by
                  connecting local frames of reference.},
