OpenMarineCharts

This is an attempt to create modern, beautiful, constantly updated, and eventually accurate marine charts using open data sources, open source tools, and reproducible workflows.

Current Status & Goals

🟡 Phase 1: Small scale basemap of the world 🌎

1. 🟡 Tooling and automated workflows for the creation of vector tiles
2. 🟡 Initial basemap of the world at scale 9
3. ⚪️ Infrastructure for serving and distributing (releases, website, tile server, Signal K plugin, etc)

⚪️ Phase 2: Medium scale regional charts 🗺️

1. ⚪️ Incorporate Regional hydrographic/bathymetry data
2. ⚪️ Incorporate OpenSeaMap data
3. ⚪️ Incorporate relevant OpenStreetMap data.

⚪️ Phase 3: Large scale local charts 🗾

1. ⚪️ Tools to record and overlay vessel's own sounder data
2. ⚪️ Incorporate local hydrographic/bathymetry data
3. ⚪️ Incorporate crowd-sourced bathymetry data

✅ Done - 🟡 In progress - ⚪️ Not started
