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