Phenological date matching for invasive species mapping: code for an R workflow (version 1.0.0)
April 1, 2026
This code set is an R workflow for phenological date matching to provide an open-source solution for projects with limited funding to allow users to calculate Normalized Difference Vegetation Index (NDVI) from sentinel-2 imagery dates specified by a user supplied date raster (phenology raster) for mapping and forecasting geographic distributions of invasive plant species at large spatial extents (e.g., continental scales).
