| exactextractr {exactextractr} | R Documentation |
exactextractr quickly and accurately summarizes raster values over polygonal areas, commonly referred to as zonal statistics. It provides the following functions:
exact_extract generates a data frame of grid cell values
and the fraction of the cell's area that is
covered by a polygon. It can also compute
statistics on these values without returning them
directly.
coverage_fraction generates a raster whose values represent
the fraction of each grid cell (0-1)
covered by a polygon.
