Usage

summarize_by_poly(hsi_model, polys, progress = TRUE)

Arguments

hsi_model

raster; A raster HSI model.

polys

sf; A polygon used to derive be summaries from the raster.

progress

logical; TRUE displays a progress bar during processing.

Value

A data frame containing polygons summarized by the following fields:

  • ID - Polygon unique identifier. Derived from polys' row.names.

  • hu_<model_name> - HSI score mean for the polygon. Model name is derived from the raster data names attribute via names().
