This paper proposed an objected-oriented method to extract road from high-resolution satellite image.Firstly,class of building was got using chessboard segmentation by setting vector image of buildings as a thematic layer.And then it received a general classification by nearest-neighbored sampling to image objects.Those objects were got through multi-scale segmentation.Lastly,road was optimized using road-knowledge base.The experiment result showed that it could obtain better effect than traditional method.
