摘要: 地理表达是地理学的一个基本问题,也是地理信息科学研究面临的一个重大挑战。从地理表达机理、内容和形式的角度,对近期地理表达研究进行了总结。本质上,地理表达是一个空间认知、信息转换与信息传输的交互过程。地理表达内容涉及地理实体及其空间关系、不确定性、地理动态及地理本体等方面。地理表达形式经历了从自然语言、地图到GIS的演变过程;近年出现了多种新型表达形式,如虚拟地理环境、地理增强现实、地理超媒体等;并分析了当前地理表达的局限性。最后,从发展新的时空过程表达方法、地理表达形式的选择与协同问题等方面对地理表达的研究拓展进行了讨论,并根据UCGIS的研究计划,从表达理论、表达方法以及计算支持的角度,对地理表达研究目标进行了展望。

Abstract: Geographic representation is a fundamental problem of geography. It is a major challenge of geographical information science. From the mechanism, contents and forms of geographic representation, this article summarized the recent researches in this field. Geographic representation is an interactive process of spatial cognition, and information transformation and transport. The content of geographic representation includes four aspects: (1) geographic entity and its spatial relations, such as objects and fields entities, or topology, azimuth, measure and neighboring relations; (2) geographic uncertainty, such as the disposal of the fuzzy and non-precision problems; (3) geographic dynamics, including five driving factors, such as spatiotemporal activities, events, processes, change and movement; (4) geographic ontology, such as the disposal of the geographic concepts and knowledge. From the point of view of evolution, geographic representation goes through the development process from natural language description, map to GIS; and as the technology advances, new forms are also developed, such as virtual geographic environments, geographic augmented reality and geographic hypermedia. The limitation of current geographic representation research is also analyzed. Finally, the extensions to geographic representation are discussed from the aspect of the development of new representation methods of spatial-temporal process and the selection and collaboration of geographic representation form, etc. The perspectives of geographic representation are also proposed in theory, method and computation according to the UCGIS research plan.
