A vector chart is a series of points and lines that make up the features on a chart. Details on the chart can be turned on and off. Objects on the chart can be clicked on to learn more details. Depths can be monitored to warn before grounding. When zooming in and out of a vector chart only the geographical features grow larger or smaller where text keeps it’s same size and orientation.
All Chartworx electronic chart systems support C-MAP by Jeppesen digital cartography, certified by Det Norske Veritas (DNV) in accordance with the specifications as laid down in ISO 19379 (International Standard for content, quality, updating and testing of Electronic Chart System (ECS) database).
C-Map uses official paper charts or digital information provided by Governmental Hydrographic Offices. Paper charts are digitised and converted to C-Map’s unique digital data format. This also happens with the digital information received from the Hydrographic Offices.
The digitised data is compiled into a seamless database. The whole process is subject to quality control procedures as laid down in QC procedures for official Electronic Navigational Charts (ENC).
C-Map by Jeppesen digital charts for the professional market are distributed as “C-MAP Professional +” and offer world wide coverage.
The quality of the database is depending on the quality of the information as provided by the Hydrographic Offices. Charts are subject to frequent changes, depending on the area. Charts of the North Sea change almost on a daily basis particularly in shallow areas where frequent surveys (in some areas on a weekly basis!) result in regular change of navigation buoys. Also continuous offshore oil exploration activities do result in frequent chart changes. The quality of databases is therefore much dependent on the frequency of updating of the digital charts.
C-Map keeps its digital chart constantly updated based on the corrections as published by the Hydrographic Offices C-Map produces the latest version of all available databases monthly. Subscribers to C-MAP data receive a new CD / DVD every 4 months and have access to the unique Real Time Updating (RTU) service from C-MAP which enables round the clock update facilities.
