【摘要】 针对多尺度空间数据联动更新技术体系不完善的问题,该文提出了一套系统完善的多尺度空间数据联动更新技术体系。该技术体系以模式识别理论为基础,以"更新信息检测—自适应增量更新—更新信息多尺度匹配与传递"为主线,实现了模式识别理论技术与多尺度空间数据联动更新应用的深度融合,为空间数据快速更新提供了重要的技术支撑和保障。基于广州市增城区空间数据联动更新的实验结果表明:该文提出的方法对于复杂城市区域多尺度空间数据联动更新是非常有效的。更多还原

【Abstract】 Aiming at the problem which the technical system of multi-scale spatial data linkage updating is imperfect,this paper puts forward a technical system for multi-scale spatial data linkage updating.The technical system is based on pattern recognition theory and takes"updating information detection-adaptive incremental updating-updating information multi-scale matching and transmission"as the main line,which realizes the deep integration of pattern recognition technology and multi-scale spatial data linkage update application and can provide important technical support and guarantee for the rapid updating of spatial data.The experimental results in Zengcheng district,guangzhou shows that the method proposed in this paper is very effective for multi-scale spatial data linkage updating in complex urban areas.更多还原
