A Design and Implementation of SENC Structure for efficient storage of S-57 spatial data

Hee-Yong Lee

Abstract

The ENC standard, S-57 Specification was established to exchange hydrographic data between it’s users such as HOs ECDIS users, etc. The digital navigation chart which is produced according to the S-57 Specification is called an ENC(Electronic Navigational Chart) and the SENC(System ENC) is a by-product of ENC suitable for computer graphics system. Even though the efficient structure of SENC is a key element of measuring ECDIS performance, the amount of papers about these topics are small compared with other research fields. In this paper, the author designed an efficient spatial data structure of SENS, called Mesh. This paper also includes the implementation result of the “Mesh” which displays SENC on computer screen.
