道路网约束下的多尺度面状要素自动匹配
|
摘要
为解决多尺度空间数据库关联更新中自动识别匹配同名地理要素的问题,以多尺度面状目标为研究对象,提出先根据小比例尺道路网约束对面状实体集进行粗匹配,再对中间结果进行几何分析和属性匹配的处理方法,建立起针对多尺度数据的关联匹配数据库,确立多尺度数据同名实体的对应关系,为多尺度数据库的一致性维护提供技术保障。实验表明,此方法的匹配效率和查全率都比传统匹配方法有了显著提升,证明了其有效性。
The thesis aims at solving the problems in automatically identifying and matching the geographic elements with the same name during the correlation upgrading of multi-scale spatial database. Taking multi-scale polygon features as the research object,this paper put forward the method by setting a coarse matching of the polygon features under the constraint of road network in a small scale,and then made a geometric analysis and attribute matching of the results. Consequently it established a correlation matching database and forms the corresponding relationship among multi-scale data features with the same name,which provided a technical guarantee for the consist maintenance of multi-scale database. Experiments show the efficiency of this method and matching recall rate than the traditional matching method has been significantly improved,demonstrating the effectiveness of the method.
