calculate_prism: Calculate PRISM covariates

Description

Extract PRISM values at point locations. Returns a data.frame object containing locs_id and PRISM variable. PRISM variable column name reflects the PRISM variable and circular buffer radius.

Usage

calculate_prism(from, locs, locs_id = "site_id", radius = 0, geom = FALSE, ...)

Value

a data.frame or SpatVector object

Arguments

from

SpatRaster(1). Output from process_prism().

locs

data.frame. character to file path, SpatVector, or sf object.

locs_id

character(1). Column within locations CSV file containing identifier for each unique coordinate location.

radius

integer(1). Circular buffer distance around site locations. (Default = 0).

geom

FALSE/"sf"/"terra".. Should the function return with geometry? Default is FALSE, options with geometry are "sf" or "terra". The coordinate reference system of the sf or SpatVector is that of from.

...

Placeholders.
