国家水文数据集(NHD)是美国的一个基础性地理空间数据来源,它能够进行广泛和多样化的环境研究,并在多种情况下支持决策。然而,考虑到可能不一致的初始收集和水文变化,NHD需要定期验证和更新。此外,使用NHD数据的系统或工具必须管理在NHD(NHD HR)的高分辨率版本中发生的定期更新。本研究通过建立一个名为OpenCLC的开源软件工具来填补这一空白,该工具可以自动识别两组水文流线之间的匹配和不匹配的线要素。除了识别两个版本的NHD线路之间的差异外,结果还可以应用于提高NHD HR内容的质量。OpenCLC在计算可伸缩性方面远远优于现有的最佳商业软件,它作为CyberGIS工具包的一部分被广泛使用,以造福于广泛的环境和地理空间科学界。
The National Hydrography Dataset (NHD) is a foundational geospatial data source in the United States that enables extensive and diverse environmental research and supports decision-making in numerous contexts. However, the NHD requires regular validation and update given possible inconsistent initial collection and hydrographic changes. Furthermore, systems or tools that use NHD data must manage regular updates that occur within the high-resolution version of the NHD (NHD HR). This research contributes to filling this gap by establishing an open-source software tool named OpenCLC, which automatically identifies matching and mismatching line features between two sets of hydrographic flowlines. Aside from identifying differences among two version of NHD lines, results can be applied to improve the quality of NHD HR content. OpenCLC significantly outperforms the best available commercial off-the-shelf software in computational scalability, and it is made widely available as part of the CyberGIS Toolkit to benefit broad environmental and geospatial science communities.
