Rwapor: Download WaPOR and AgERA5 Data

Downloads and processes WaPOR (Water Productivity Open-access portal) and AgERA5 raster data from the FAO GIS Manager API. Provides functions for extracting time series, calculating zonal statistics for regions and polygons, downloading raster maps, unit conversion, and seasonal crop water productivity analysis. Supports WaPOR Level 1, Level 2, Level 3 data products and AgERA5 climate variables. Includes an interactive Shiny dashboard for data exploration and analysis with crop mask integration and seasonal indicator computation.
