The Next Generation of Digital Spatial Technologies: Error Utilization, Thematic Map and Remote Sensing Integration, Spatial Operators, and Data Structures
نویسندگان
چکیده
It is suggested that new ways of thinking about spatial analysis are required to optimize the use of digital tec hnologies. “Real-world-to-map” simplifications must be quantified and incorporated into spatial analysis with particular emphasis on boundary and category error. This could also lead to a better way to integrate thematic map-based and remotely-sensed data. However, such developments will require the creation of a new family of spatial operators which work on “error” or “uncertainty” surfaces rather than categorical thematic maps. These operators should work across maps and polygon boundaries rather than by considering absolute location to be the primary characteristic of spatial entities. The use of these concepts in digital spatial technologies may also require the development of an alternative data structure. The Voronoi diagram is presented and discussed as a possible solution.
