Major map engine update, new terminal inspired themes
Release 1.0.19
Version 1.0.19 ships with a new map engine that can render NOAA ENC charts natively. Also: new themes.
Native S-57 support
Previous versions of Luna Marine Charts used pre-processed map tiles derived from chart data. Starting in 1.0.19, the app reads S-57 files directly. This means:
- Faster Chart Rendering: the app renders features straight from the source data instead of from pre-made tiles, which allows us to optimize the size of each tile.
- Faster updates: We no longer have a complex tiling system that needs to run to process chart updates.
- S-63 coming soon: encrypted S-63 charts, used by many countries outside the US, are in the works.
You'll need to re-download any chart packages you already have. It only takes a few seconds per package.
New themes
Three new map themes have been added, inspired by classic terminal color schemes:
- Dracula: dark theme with high-contrast accents
- GruvBox: warm, earthy tones
- Njord: a muted theme named after the Norse god of the sea
Themes can be changed in Display Settings.
