| 摘 要： | 根据建立大比例尺多级土地利用数据库的需要,在进行面状道路数据综合时,对道路进行分类,保留需保持面状的道路面,将不符合要求的道路从网络状道路面中分离出来,并根据需要予以转线或删除,形成新的小比例尺的线面混合道路数据。同时,将删除的道路面分割并归并进相邻图斑,以保证土地数据面状连续的特点。 |

| Abstract: | To establish large-scale multi-level database of land use,we propose a new method to generalize polygon roads to polygon-polyline mixed roads.When integrating road polygon datasets,the network road polygons are divided into three types,retention,deletion and reduced maintenance parts.Deletion parts are removed,and the reduced maintenance parts are changed into linear roads,and the retention parts and the linear roads form the new mixed road dataset of the new target scale.Moreover,the deletion and reduced maintenance road polygons will be divided into small pieces and then incorporate into polygons which matches these pieces in order to ensure the land use data having no gaps. |
