| 摘 要： | 多级比例尺矢量地图数据库一旦建成以后,数字制图的核心就从数据生产转为数据更新.小比例尺矢量地图数据库建库时必须依靠大量人机交互从大比例尺数据派生,但更新时再采取各比例尺分别独立更新的策略显然就不合时宜,既消耗大量人力和财力,又不能保证不同尺度数据之间的一致性.提出一种多尺度矢量地图数据关联自动更新方法,对于已经建成的多... |

| Abstract: | After building multi-scale map database,the mission of digital mapmaking is transferred from data producing to data updating.The small scale map database is derived from great scale database by a lot of man-machine interactions,after building,if we update these multi-scale database one by one,it will use a great deal manpower and material resouce,and this will not assur the quality of data.The paper introducs a method of relating automatic updating for vector multi-scale map database,it makes automatic upda... |
