NetCDF (Network Common Data Form)

Open Beta

.nc · application/x-netcdf

NetCDF is a self-describing binary format for scientific data and the de facto standard in climate science, oceanography, and satellite remote sensing (ERA5, CMIP6, MODIS). On osm2cdr the OSM to .nc export works honestly like this: for each layer we take feature centroids (longitude/latitude) plus their attributes and write them through xarray as variables sharing a feature-index axis. The result is a compact point dataset with metadata (title, source, bbox), not a ready-made climate density grid cube — that would require a separate aggregation step. The file opens in xarray, Panoply, GDAL, and any NetCDF tool.
