More Information
Summary:The invention discloses a method for extracting OSM map data to quickly construct a regional road network, which comprises the following steps of: setting a corresponding relationship between the analysis precision of the regional road network and a label value in the OSM map data, and screening and extracting the downloaded OSM map data according to the label value. Obtaining road section and node data required under the setting precision; and carrying out attribute judgment and conversion on the extracted data to form spatial data and attribute data files of road sections, nodes and topological points in the regional road network. According to the method, the user can analyze the OSM map data according to the precision requirement of constructing the regional highway network, and finally construct the regional highway network map expressed by the computer, so that the time and the workload of manually drawing the network are saved. 本发明公开了一种提取OSM地图数据进行区域公路网快速构建的方法，所述方法对区域公路网解析精度与OSM地图数据中的标签值设置了对应关系，根据标签值对下载得
