A concise ChartPlotter/Navigator. A cross-platform ship-borne GUI application supporting * GPS/GPDS Postition Input * BSB Raster Chart Display * S57 Vector ENCh
a. Opencpn was built with the following objectives in mind.
i. Intended use as primary navigation interface for vessels with full-time helm-visible navigational suites. Other tools may be better for offline route planning, tide and current prediction, online logging, etc. ii. Quick startup and shutdown. iii. Those and only those toolbar buttons really needed for daily operation. iv. Portability, thus wxWidgets core components. Currently tested and in production use on Windows, MacOS, Linux and Android. v. Conventional ( i.e. popular and modern ) chart format support. In the real world, this means BSB format raster charts, and S57ENC format vector charts.
And, of course, opencpn is all GPL'ed (or equivalent) Open Source code.
Personal Note: Opencpn is in primary daily use as the navigation package aboard M/V Dyad, a 48 ft trawler yacht cruising from Newfoundland to the Bahamas yearly.
