The Research of Selection Model Based on LOD in Multi-Scale Display of Electronic Map

摘要：

This paper proposes a selection model based on LOD to aid the display of electronic map.The ratio of display scale to map scale is regarded as a LOD operator.The categorization rule,classification rule,elementary rule and spatial geometry character rule of LOD operator setting are also concluded.

关键词： Electronic map Level of detail (LOD) Multi-scale display Selection Operator Spatial geometry character
