Nautograf

Nautograf is a viewer for marine vector charts. It is inspired by OpenCPN which is the only nautical chart software that is open source and runs with offline chart data. The motivation behind Nautograf is to provide an application similar to OpenCPN, but provide a smoother zooming and panning experience, better rendering quality and a more modern code base. Because getting chart data is not free for many geographic areas, Nautograf currently supports only "oesu" charts from o-charts.org which has good coverage for the western world. Support for S-57 such as provided by the NOAA may be added in the future. Nautograf is experimental software and comes without any warranty. Do not use it for navigational purposes.
