GIS中地理信息综合功能的研究和开发是当的GIS技术进步与应用发展所面临的一个新挑战。首先研究了GIS中地理信息综合功能的意义、基本内容及其实现途径, 然后介绍了作者所提出的基于分形分析的自动综合算法和实例, 最后分析了GIS地理信息综合功能研究中需要进一步解决的问题。

Geographical processes are scale dependent and numerous applications in GIS require changing degrees of detail or scale, thus geographic information should be made available at multiple levels of abstraction. In this sense, people are now beginning to realize the lack of generalization functionality with respect to the development of value-added products from the initial database and the update of existing databases, particularly when multiple scales are involved. Geographical information generalization is a new challenge to technical progress of GIS. This paper focuses its basic meaning and realization firstly, then introduces a new automatic algorithm based on fractal analysis, which is proposed by the authors, and discusses the further problems of generalization in GIS lastly.
