ISBN: 0415482461
Format: PDF
Quality: Scanned pages
Number of pages: 1136
Description: Electronic navigation, although still relatively new, is becoming increasingly more common, particularly on commercial vessels. This handbook offers a wealth of detailed information about how different charting systems operate and answers the most commonly asked questions regarding electronic charts (ENC, RNC, DNC) and electronic chart systems (ECDIS, RCDS, ECS). The first resource to provide so much detail on all facets of ECDIS and Electronic Charting Systems, it is certain to serve as the bible for ECDIS users for years to come. It not only provides information for training programs but also for engineers maintaining ECDIS Systems in the field.
The book will be of specific interest to those who need to know about selection, implementation, operational use, benefits, and management of these systems, without getting into the technical details of how ECDIS/GIS actually works.
