Description

Summarize the raster HSI model by polygon.

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.

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

• count_<model_name> - Count of cells for the polygon.

• acres_<model_name> - Area in acres for the polygon.
