This is the name of a Windows application I am working on in my spare time. The objective is to develop a navigation software using OpenStreetMap and OpenSeaMap tiles with the ability to:

  • Download GRIB files;
  • Compute optimal trajectory for the current Ship vs winds and currents;
  • Receive GPS signal from an antenna connected to the PC;
  • Still allow classical navigation methods like marks bearing and celestial navigation;
  • MOB feature.

LeONAR is in its very early stages of development. It is currently limited to:

  • Asynchronous download of OSM and OSeaM tiles to AppData cache from tiles server;
  • Asynchronous tiles display;
  • Map object selection by clicking on the map;
  • Correctly manage the coordinates system;
  • Export/load user data from XML-format file;
  • Retrieving GPS position, COG and SOG from connected antenna (only displaying in GPS data form for the time being).

More to come!
