The field of spatial reasoning investigates representations and inference mechanisms that enable one to draw conclusions from spatial information. It is also concerned with computational implementation of spatial reasoning algorithms and their exploitation in applications such as robot control, image processing, and manipulation of geographic information. This entry briefly reviews the origins and development of spatial reasoning. It describes some of the most significant subdomains of spatial information and explains the most widely used techniques for computing spatial inferences. Finally, the role of spatial reasoning in geographic information systems (GIS) is considered.

Origins of the Field of Spatial Reasoning

The study of spatial reasoning dates back to ancient times. It is known that the Egyptians used a variety of systematic procedures for spatial inference, especially with ...
