calc_prepare_locs: Prepare extraction locations

In amadeus: Accessing and Analyzing Large-Scale Environmental Data

Prepare extraction locations

Description

Prepare the point locations for extracting data by transforming locs to a SpatVector, projecting to the coordinate reference system of from, and creating a data.frame containing locs_id for retaining extracted values.

Usage

calc_prepare_locs(from, locs, locs_id, radius, geom = FALSE)

Arguments

from	SpatRaster(1) or SpatVector(1). Output from process_\*(). Passed from calc_\*().
locs	data.frame. character to file path, SpatVector, or sf object. Passed from calc_\*().
locs_id	character(1). Column within locations CSV file containing identifier for each unique coordinate location. Passed from calc_\*().
radius	integer(1). Circular buffer distance around site locations. (Default = 0). Passed from calc_\*().
geom	logical(1). Should the geometry of locs be returned in the data.frame? Default is FALSE, options "sf" or "terra" will preserve geometry, but will use terra for extraction.

Value

A list containing SpatVector and data.frame objects
