The visualization of multi-scale cartographic has been one of the bottleneck problems in the realization of electronic maps.People have found some effective methods to solve this problem.This paper uses LOD(a method applied in making three dimension models)and cartographic generalization to realize visualization of electronic map.By constructing some specific geographic feature's LOD models,the paper provides a standard and a mathematics method to visualize electronic maps.At the same time,the sort methods of geographic features,the setting of LOD level parameters and some integrated arithmetic are discussed.The method has been realized in the projects of Longgang electronic atlas.
