Construct a SpatRaster from a map

This function convert a GeoPressureR map object into a terra::SpatRaster with the data of each stationary periods stored in a different layer.

Usage

rast.map(x, names = glue::glue("#{map$stap$stap_id}"), crs = "epsg:4326", ...)

Arguments

x

a GeoPressureR map object

names

names of the SpatRaster layers created. See terra::names.

crs

character. Description of the Coordinate Reference System (map projection) in PROJ.4, WKT or authority:code notation. See crs. If this argument is missing, and the x coordinates are within -360 .. 360 and the y coordinates are within -90 .. 90, longitude/latitude is assigned

...

additional parameters for terra::rast

Value

A terra::SpatRaster object.
