从空间分析的角度回顾了地理信息系统(GIS)领域，空间分析是常见的输入、存储、分析和输出四部分模型的关键组成部分，输入受到人工方法的限制和扫描时的歧义问题。产出方面的发展潜力被认为仅限于地理信息系统操作的查询模式，并取决于放弃制图模式。存储方法的讨论围绕栅格和矢量的辩论以及将两个空间维度表示为一个维度的必要性来组织。提出了一种地理信息系统空间分析操作的分类方法和通用数据模型。对实施的前景进行了讨论，认为这取决于国家和国际学术研究的适当组织规模。
Abstract The field of geographical information systems (GIS) is reviewed from the viewpoint of spatial analysis which is the key component of the familiar four-part model of input, storage, analysis and output Input is constrained by the limits of manual methods and problems of ambiguity in scanning. The potential for developments in output is seen to be limited to the query mode of GIS operation, and to depend on abandoning the cartographic model. Discussion of storage methods is organized around the raster versus vector debate and the need to represent two spatial dimensions in one. A taxonomy of GIS spatial analysis operations is presented together with a generic data model. Prospects for implementation are discussed and seen to depend on appropriate scales of organization in national and international academic research.
