Abstract:

Geocomputation, as one of the cores of geographic information science (GIScience), focuses on methodological problems, including modeling, algorithms, computational systems, and the general methodology in the field of GIScience. With the rapid development of GIScience in China, five trends of geocomputation are concluded and presented respectively: (1) Geo- data mining refers to the means of discovering geographic knowledge concerning geographical problems in ways of model processing and computation of various kinds of data; (2) Spatial operational research is widely applied to the field of geography, with its algorithms simpler and more precise and its accuracy higher; (3) Multi- Agent System(MAS) has become the third important method of geography research ranking after induction and deduction; (4) Quantitative computation in discrete space turns into the necessary fundation of computation in geographic space; (5) Geographic ontology is essential to the progress of GIScience as well as the development of geography in general. Some new direction have appeared on geocomputation, they include: 1 computational pattern, as is, Cooperative Computing, Pool Computing; spatial computation complexity; and mappattern recognition.

Key words: discrete space, geo- data mining, geocomputation, multi- agent system, ontology, spatial operation
