摘要
海岸带地形数据来源的多样性,造成了数据模型、格式不同,数据基准也存在差异。消除这些不一致性,建立海陆地形模型的统一表达模型,是海岸带管理、舰船登陆决策的基础。本文在国内外研究的基础上,分析了海陆数据集成中的主要问题,讨论了海陆地形统一表达的关键技术,为实现无缝的海陆地形模型奠定了技术基础。
Because of the diverse coast data, not only data models and formats but also data datums are different. So it is the basis for coast management and ship landing decision to eliminate these variances and to found unified expression of sea-land terrain model. In the paper, based on researches both at home and abroad, the main problems of sea-land data in tegration are analyzed, and then key techniques of unified expression of sea-land terrain are discussed, which lay the tech- nique basis for sea-land terrain model.
