摘要
为解决全球海域多波束测深数据查询使用不便的问题,通过数据分块实现海量数据处理,使用逐点插值算法构建数字水深模型,将晕渲图与数字水深模型组合构建可视化查询服务,实现基于浏览器查看水深数据和查询水深值等功能。对已有的全球海域多波束测深数据进行了处理,结果表明该方法对海量数据有着很好的承载能力,构建的数字水深模型能够反映测深点分布情况,Web查询服务响应迅速;同时该方法基于常用GIS软件处理数据,可操作性强,可用于海量多波束测深数据管理。
To address the inconvenient issue of querying and using global multibeam bathymetry data,we used data partitioning to handle massive data processing and interpolated the data using point-by-point interpolation algorithm to build a digital bathymetric model.We combined the shaded relief map with the digital bathymetric model to construct a visualization query service,which enables accessing bathymetry data and querying via web browsers.We processed the existing global multibeam bathymetry data and found that this method has good carrying capucity for handling massive data,and the constructed digital bathymetric model can reflect the distribution of the bathymetry points.The web query service also offers a responsive performance.Our proposed method used GIS software to process data and is highly operable,thus it can be applied to manage a large amount of multibeam bathymetry data.
