Computes summary statistics for metric rasters inside corridor polygons.
Usage
summarize_isobath_terrain(
metrics,
corridors,
fun = c("mean", "sd", "min", "max", "median"),
na.rm = TRUE,
exact = FALSE,
...
)Arguments
- metrics
A metric raster stack.
- corridors
Corridor polygons.
- fun
Summary functions.
- na.rm
Logical. Remove missing values.
- exact
Logical. Use coverage-fraction-weighted exact intersections through
summarize_terrain()when available.- ...
Additional arguments passed to
summarize_terrain().
Examples
bathy <- read_bathy(blueterra_example("bathy"))
terrain <- derive_terrain(bathy, metrics = c("slope", "bpi"))
corridors <- make_isobath_corridors(bathy, depths = -50, width = 5)
