What is a .CDF file?
CDF is a NetCDF file storing array-based scientific data like climate and ocean models.
- Did you know
- NetCDF, from Unidata, is a mainstay of climate and earth-science data.
- NetCDF was created at Unidata, part of the University Corporation for Atmospheric Research, and is funded by the US National Science Foundation.
- It is a self-describing format whose header records the layout of its data arrays, so files move freely between different machine architectures.
- What Analyser reads
- Inspect geospatial and GIS files without a map: TopoJSON, OpenStreetMap XML, Esri Shapefile siblings (SHP/SHX/DBF/PRJ/CPG), world files, GML, NMEA GPS logs, IGC flight logs, MapInfo TAB/MIF, GDAL VRT, PMTiles, DTED terrain, Esri ASCII grids and SRTM .hgt - surfacing CRS/EPSG, feature/record counts, bounding boxes and elevation ranges. GRIB/NetCDF/GeoPackage/MBTiles/MrSID/ECW identified.
- Depth of analysis
- .CDF is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .CDF file
- Drag a .CDF file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
