What is a .GDB file?
A .gdb is an Esri file geodatabase - a folder holding many GIS layers and tables.
- Did you know
- The file geodatabase is Esri’s modern container for organising GIS data.
- An Esri file geodatabase is a folder of binary files, the successor to the Access-based personal geodatabase.
- Each table or feature class can reach a terabyte by default, far beyond what shapefiles were built to hold.
- 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
- .GDB 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 .GDB file
- Drag a .GDB 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.
