Abstract

Map objects' displacement is an important operator in the map generalization and spatial information visualization. In this paper, the constraints of map objects displacement and their satisfaction method with the finite element method are discussed, in which the constraints of map objects displacement and strategies of parameters of finite element method in the displacement process play important roles for the displacement result, and compromised with the spatial reasoning method, a progressive node displacement method is discussed in this paper, which is examined with a road widening case. And the result shows that the force and the force propagation can be considered comprehensively in this method, through which unnecessary map object displacement can be avoided.
