IHO S-102水深表面数据模型及其应用分析

Analysis of Data Model and Application of IHO S-102 Bathymetric Surface

IHO S-102作为水深表面产品规范,为海底格网数据的生产奠定了基础。从元数据、覆盖类型、切片模式、图示规则、要素模型以及应用格式等方面分析S-102的数据模型,在此基础上,介绍了S-102产品的生产工具,以及部分海道测量机构从事S-102产品规范开发、数据集生产与应用测试的案例,最后,阐述了S-102产品生产中应关注的主要问题与实际应用情景,为我国开展海底格网产品的生产提供借鉴。

IHO S-102 lays a foundation for the production of bathymetric grid chart products.This paper analyses the data model of S-102 from the aspects of meta-data,data coverage type,tiling rule,portrayal scheme and data format of bathymetric grid,and the main production tools of S-102 production.Moreover,it expounds the cases mainly engaged in the development and data production of S-102 product specification.Finally,it introduces the main factors of production of S-102 data,which helps us carry out the production of bathymetric three-dimensional grid datas.
