Supported indexes include: - Parametric Rao’s quadratic entropy (classical and multidimensional); - Shannon’s diversity index; - Pielou’s evenness index; - Hill’s generalised entropy; - Rényi’s generalised entropy; - Berger-Parker index; - Cumulative Residual Entropy (CRE) ## New Features - Time Series Integration: The package recently integrated time series of remote sensing data to derive Rao’s index, for example considering plant phenology. See the vignette: [Multidimension Rao’s Index](https://mattmar.github.io/rasterdiv/articles/rasterdiv_03_Advanced_multidimension_Rao.html). - Helical Graphs: Prepare and plot time series with “helical graphs”. See the vignette: [Visualising rasterdiv indexes with Helical Plots](https://mattmar.github.io/rasterdiv/articles/rasterdiv_05_Helical_Plots.html). ## Key Features - Moving Window and Area-Based Calculations: Derive indexes using a “moving window” approach (all functions) or area-based Parametric Rao’s quadratic entropy via [*paRao()*](https://mattmar.github.io/rasterdiv/articles/rasterdiv_area_based_Rao.html) ## Learn More on **rasterdiv** - [***rasterdiv**—An Information Theory tailored R package for measuring ecosystem heterogeneity from space: To the origin and back*](https://besjournals.onlinelibrary.wiley.com/doi/full/10.1111/2041-210X.13583); - [*Measuring diversity from space: a global view of the free and open source rasterdiv R package under a coding perspective*](https://link.springer.com/article/10.1007/s42974-021-00042-x); - [*From zero to infinity: Minimum to maximum diversity of the planet by spatio-parametric Rao’s quadratic entropy*](https://onlinelibrary.wiley.com/doi/full/10.1111/geb.13270) - [*Helical graphs to visualize the NDVI temporal variation of forest vegetation in an open source space*](https://www.sciencedirect.com/science/article/abs/pii/S157495412200406X) - [*Phenological Diversity Trends with Remote Sensing Datacubes*](https://www.researchgate.net/profile/Matteo-Marcantonio/publication/381288639_Phenological_Diversity_Trends_with_Remote_Sensing_Datacubes/links/6666a0fbb769e76919269fa1/Phenological-Diversity-Trends-with-Remote-Sensing-Datacubes.pdf)
