Map transformation and aggregation methods for spatial decision support

摘要: The performance of policy alternatives for environmental management is often represented in maps. These maps are used to compare and ultimately select the one preferred. Since most people use reference everyday life, such as road or town maps, they familiar with them consider an appropriate decision support instrument. In practice effective a difficult task many people. Spatial evaluation methods designed this task. help maker by structuring simplifying map representations alternatives. This can be done transformation aggregation information presented map. transformation, transformed combined way that only relevant presented. For aggregation, indices defined represent certain aggregate features decision. chapter developed comparison mapped Green Heart Netherlands. Seven examples questions illustrate spatial methods. It shown these increases understanding differences between do not provide single answer, which alternative best, but result series answers depending on specific asked. All included small software package invites makers experiment their problem.
