Marine Geographic Information Systems

Abstract

This chapter describes the nautical and hydrographic application of geographic information systems. Based on a general description of the regulatory framework of the applicable performance requirements and technical norms for electronic chart display and information devices (ECDIS), a detailed explanation of the functional specifics of modern electronic sea charts follows. Emphasis is placed on the user interface and its functions for general route planning and route monitoring as well as the specific look-ahead functionality and integration of AIS (Automatic Identification System) data as significant navigation safety enhancements. Further sections deal with electronic chart data and services for their wireless dissemination. The chapter concludes with a presentation of the universal hydrographic model S-100 (based on ISO standards) as the fundamental database for e-navigation.
