projectInputs: Project Raster* or Spatial* or sf objects

Description

A simple wrapper around the various different tools for these GIS types.

Usage

projectInputs(x, targetCRS, ...)
# S3 method for Raster
projectInputs(x, targetCRS = NULL, rasterToMatch = NULL,
  ...)
# S3 method for sf
projectInputs(x, targetCRS, ...)
# S3 method for Spatial
projectInputs(x, targetCRS, ...)

Arguments

x

A Raster*, Spatial* or sf object

targetCRS

The CRS of x at the end of this function (i.e., the goal)

...

Passed to projectRaster.

rasterToMatch

Template Raster* object passed to the to argument of projectRaster, thus will changing the resolution and projection of x. See details in postProcess.

Value

A file of the same type as starting, but with projection (and possibly other characteristics, including resolution, origin, extent if changed.
