Abstract:Model generalization is the foundation of map generalization, which is conceptual generalization of spatial information in digital environment. Model generalization modifies spatial relations and semantics relations of map objects to reduce spatial information, makes it simpler and convenient to represent geographic information in smaller scale. The paper discusses the concept and meaning through the contrast of model generalization and cartographic generalization, then illustrates the model generalization in topological and semantic aspect, generalization decision.
