The goal of spatial cognitive engineering is to design spatial information systems and services based on the principles of human communication and reasoning. It is an interdisciplinary endeavor, involving the disciplines of geographic information science, cognitive science, computer science, and engineering. A special focus is human-computer interaction based on the integration and processing of the spatial and temporal aspects of phenomena. The field of spatial cognitive engineering is motivated by the belief that useful and usable solutions to people's geospatial problems can only be found by considering the cognitive abilities and strategies people bring to the problem-solving process.
