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.

주요 기능

✓Feature centroid coordinates (lon/lat) and attributes — one variable per layer field

✓One .nc file per export, layers merged via xarray.merge with shared global attributes (title, source, bbox)

✓Written via xarray + netCDF4; if absent, a GDAL-driver fallback rasterizes layers into a NetCDF grid

✓Self-describing binary container: metadata lives inside the file, readable in xarray, Panoply, QGIS (GDAL), MATLAB, R

Example NetCDF export (central Moscow, 1x0.5 km) — Example: central Moscow, ~1×0.5 km, medium detail

Format specifications

Open standard
2D only
Lossless (no quality loss)
Stores feature attributes
Output: 1 file
A single .nc written via xarray: feature centroids (lon/lat) and attributes share a feature-index axis; a point dataset with metadata, not a density grid cube.
