  "Description": "Tools for the analysis of land use and cover (LUC) time\nseries. It includes support for loading spatiotemporal raster\ndata and synthesized spatial plotting. Several LUC change\n(LUCC) metrics in regular or irregular time intervals can be\nextracted and visualized through one- and multistep sankey and\nchord diagrams. A complete intensity analysis according to\nAldwaik and Pontius (2012)\n<doi:10.1016/j.landurbplan.2012.02.010> is implemented,\nincluding tools for the generation of standardized multilevel\noutput graphics.",
