This process takes batheymetric data from GEBCO and converts it into a colorized hillshaded geotiff.
You will need:
- Gebco netcdf file here
- Docker (or a new gdal 3+ with netcdf support)
- Node >= v12
# Install dependencies
npm install @basemaps/bathymetry
# To prevent very long CI/Dev build times, mapnik will need to be manually installed
npm install mapnik
# Ensure the javascript has been built
npm run build
# Create a the data file
node build/index.js -v create --input gebco_2020.nc --docker --output gebco/
