This paper presents a method of generating a sketch drawing from geographical map images with vector representation. This method consists of two stages: generation of a road network from a vectorized image and generation of a sketch map drawing based on the road network. The road network is fundamental data for any applications, represented as a graph structure that is augmented with related attributes about roads and crossings. The characteristic of this method is to introduce a parameter, called roughness, in order to control sketch map generation. Because of the roughness, we can obtain a variety of sketch map drawings according to user's requirements. We experimentally verified that the proposed method is effective and that the roughness is valid as a psychological measure.<>
