What is a .IGC file?
IGC is the standard flight-log format from glider and paraglider GPS recorders.
- Did you know
- IGC logs are the official record used to verify gliding records and competitions.
- IGC files must record barometric pressure altitude alongside satellite position, so a record cannot be faked simply by spoofing GNSS height.
- Many IGC recorders log an Engine Noise Level value in each fix, letting officials tell whether a motor-glider ran its engine in flight.
- 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.

- Depth of analysis
- .IGC 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 .IGC file
- Drag a .IGC 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.
