Abstract
According to the feature of the Digital Raster Graphic(DRG), a novel algorithm of extracting the road networks is proposed by recognizing the graphic annotation. The annotation information and roads are identified from the original DRG by using color cluster analysis. By making use of the template matching and color cluster analysis, the annotation districts are marked. Based on the features of roads and relationships between the roads and the annotation, some methods are put forward to connect the road segments. Experimental results show that the correct rate of this method is above 98%, and it can get good result of the road extraction and obtain the annotation information in the process.关键词
