【摘要】 地理计算是地理信息科学的核心内容之一,主要研究地理信息科学的方法学问题,内容包括建模、算法、计算体系和一般方法学问题。本文介绍了地理计算的五个前沿问题:(1)地学数据挖掘从地理学问题出发,对各种数据作地理学的模型处理和结果计算以发现地理知识;(2)空间运筹在地理学中的应用日益广泛,它的算法更加简单严密、精度也更高;(3)多自主体系统模拟已经成为地理学科学研究中除归纳和演绎之外的第三种重要研究方法;(4)离散空间的定性计算是进行地理空间计算的必要基础;(5)本体论的发展是地理信息科学乃至整个地理学发展的需要。更多还原

【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 map-pattern recognition.更多还原
