Abstract
Geographic information generalization is a necessary means for scale transform of geometric and attributive information of the geographic spatial object sets under the GIS environment. This transformation relates to the complicated spatial and attributive relations within one geographic object, among different objects or elements rather than an isolated or single-elemental object. Thus, one of the ways to solve the conflicts among objects in the generalization is to adopt the strategy which is called he multi-elemental cooperative generalization (MECG), viz. to take the objects of different geographic elements into account. This paper mainly emphasizes the constrained relations (including spatial relation and structural relation) among different elements in generalization process. In this paper, a "from-above-to-below" concept model of multi-elemental cooperative generalization for some geographic elements is also discussed.
