Geo-temporal visualizationsWe have defined a format to transfer data cube “data” to thebrowser.One or many dimensions: use of coded images or JSONGeo-temporal visualizations and data cubes are a greatway of understanding how spatial data changesWe can handle millions of vector data or processed rasters
