摘要
目前数字城市、基于位置的服务等领域大规模应用地理信息,极微小尺度上的地理信息内容表达和经济分析成为地球信息科学新的挑战。属性分辨率所研究的地理信息的种类和多寡,直接影响其应用广度和深度;作为生产要素的地理信息分析引入了获取函数和作用函数;地理信息内容供给和需求问题的分析,需要回答地理信息的可用性问题;微观经济领域的内容以新的方式进入地理信息领域,引起对地理信息市场结构的研究。
Today with the gigantic societal application of spatial information in fields of digital city,LBS,etc,geography is facing challenges in describing more exquisite contents and analysis of their economic behaviors in large scale and very small areas.Attribute resolution is used to explain the types and quantity of geo-information and will influence the width and depth of its usage.In this paper,acquisition function and effect function are used to analyze geo-information as production element.It is indicated that supply and demand of geo-information is concerned and needs to answer the question of geo-information's usability.Spatial information business behavior taking into account of microeconomics rules and structure of geo-information market is also explored.
