懒猴航海

S-57新产品bENC（等深电子海图）介绍。bENC电子海图覆盖水文数据、等深线及测点数据，适用于狭窄水道航行。



    The bathymetric ENC (bENC) concept was developed by SevenCs several years ago and was presented in the September 2005 issue of Hydro International, ‘Ports and Harbours Special’. The approach aims to integrate the latest hydrographic survey data into ENC-based navigation software. According to this concept, high-density bathymetric data are kept in separate S-57 data sets. bENCs are considered a bathymetric complement. The idea is to use bENCs in conjunction with regular ENCs (official or non-official) rather than to replace them. Meanwhile, the concept has matured, a proposal for a Product Specification (Edition 1) has been finished and first applications are ready to handle bENCs.
