FlatGeobuf – vector performance for the cloud (tested with QGIS 3.24)

Thanks to the FOSS4G speech “FOSS4G – Cloud optimized formats for rasters and vectors explained,” I got first contact with the vector-format “FlatGeobuf” – and surprise also QGIS supports it 🙂 . That was an obvious starting point for testing it with some vector data and a poor network connection (~16 MBit).

Besides the information provided by the links above, http://switchfromshapefile.org/ is a nice overview of formats for storing geo-vector-data.

The test-scenario:

  • Corine-Landcover L3 for Austria stored in a geopackage-container
  • Converted the dataset to FlatGeobuf with QGIS
  • Both datasets on a fileserver with just ~16 MBit bandwith :-/
QGIS FlatGeobuf

Loading the datasets…

  • a video tells more than 1000 words… (green polys: FlatGeobuf; brown polys: Geopackage). FlatGeobuf performs great on poor connections!
