| 摘 要： | 目标匹配是实现多比例尺地图数据变化探测和更新的一个关键技术，它是依据几何、拓扑、语义等来进行判断的。同一地物在多比例尺地图中表达方式各异，甚至差异很大，可将较大比例尺面目标与较小比例尺线目标间的匹配模式归纳为6种：1∶0、1∶1、0∶1、1∶M、N∶1和N∶M。本文通过计算较小比例尺线目标的最小约束矩形(简记为MBR)...

| Abstract: | As spatial data is becoming abundant,improving of both the reuse and the quality of existing spatial data has been more concerned than ever.So it is urgent to develop approaches for spatial data integrating and updating,and object matching has becoming one of the productive solutions for data integrating and updating between multi-scale maps.It bases on the similarity of geometry,topology and semantics between multi-scale objects.In real world,objects,such as rivers,roads and houses,etc,have many kinds of f... |
