【新版 IHO 指引发布】国际海道测量组织发布新版用于海道测量地理空间数据
国际海道测量组织(IHO)发布了用于创建水海道测量空间数据的产品规格开发的新指南。
现代导航系统和地理空间解决方案使用来自各种来源的数字数据。为了促进海道测量数据和应用的整合，IHO开发了S-100海道测量数据标准，该标准可以支持该阵列，并与国际地理空间标准，特别是ISO 19000系列完全一致。
新的S-97 指南的目的是帮助在电子导航生态系统中利用S-100创建统一的产品规范。这包括所有用于IMO国际海事组织定义的海上和陆上电子导航系统(如ECDIS)的产品规范。然而S-100也有广泛的应用，可以扩展到电子导航之外。
S-100 在本质上比S-57 更灵活，并提供了图像和网格数据类型的使用、增强的元数据和多种编码格式。它还通过专门的在线注册表为功能、属性和描述提供了更灵活和动态的维护机制。S-100 提供了一个组件框架，使建立海道测量数据建模的标准化产品规范成为可能，从而在不同的数据标准和系统之间提供真正的互操作性。
S-97 适用于使用IHO 框架标准S-100(通用海道测量数据模型)的产品规格的开发人员和维护人员。
The IHO has published new guidelines for the development of product specifications for the creation of hydrographic geospatial data.
Modern navigation systems and geospatial solutions use digital data from a variety of sources. In order to facilitate the integration of hydrographic data and applications, the IHO developed S-100, a hydrographic geospatial data standard that can support this array and is fully aligned with international geospatial standards, in particular the ISO 19000 series.
The aim of the new S-97 guidelines is to assist in the creation of harmonized product specifications utilising S-100 for implementation within the e-Navigation ecosystem. This encompasses all product specifications created for use in IMO-defined e-Navigation systems, both on shore and at sea, such as ECDIS. However S-100 also has a wide range of applications that can extend beyond e-Navigation.
S-100 is inherently more flexible than S-57 and makes provision for such things as the use of imagery and gridded data types, enhanced metadata and multiple encoding formats. It also provides a more flexible and dynamic maintenance regime for features, attributes and portrayal via a dedicated online Registry. S-100 provides a framework of components that enables the building of standardized product specifications for the modelling of hydrographic data, thus providing true interoperability between different data standards and systems.
S-97 is intended for developers and maintainers of product specifications that utilize the IHO framework standard S-100 (Universal Hydrographic Data Model)
