基于整体极优对应的不同比例尺线目标一致化处理方法
|
Abstract:
空间数据不一致性问题是国际地理信息科学领域长期关注的一项基础研究课题。不一致性是衡量空间数据质量高低的一个基本指标，亦是多源、多尺度数据集成、空间数据合并的重要研究内容，其存在直接影响空间数据分析、管理和增值应用。当前有关线目标不一致性的处理研究主要针对相同（或相近）比例尺目标，采用局部简化处理方法，缺乏对空间目标整体形状结构的考虑，对不同比例尺地图数据之间的不一致性处理问题几乎没有涉及。为此，顾及不同比例尺地图空间线目标表达的详细程度差异，提出了一种基于整体极优对应的不同比例尺线目标几何特征不一致性的处理新方法，进而通过对多组不同比例尺线目标不一致性处理的对比实验验证了该方法的有效性和实用性
