Abstract: Adaptive design of electronic map is an important content adaptive cartographic visualization research.In this paper,the basic idea for adaptive design of electronic map is put forward,which is based on adaptive theory,and a framework of electronic map adaptive design system based on modularization is built firstly.Secondly,adaptive design mechanism of electronic map and some key issues in its implementation are discussed.And lastly,experiment is conducted to prove the operability and effect of electronic map adaptive design.The results show that the modules in the electronic map adaptive mechanism are easy to be realized by programming,and each module is convenient to be contro
