Import generic raster file

Description

The function import the first layer of a generic raster file. Data are imported as an array of x, y, z columns.

Usage

importRaster(
  file = file.choose(),
  k = 1,
  kz = 1,
  dx = 0,
  dy = 0,
  destaggering = FALSE,
  variable = NULL,
  verbose = FALSE
)

Arguments

file	The raster file to be imported.
k	A numerical factor to be applied to x and y coordinates (default = 1).
kz	A numerical factor to be applied to z values (default = 1).
dx	Shifts x coordinates by dx (default = 0).
dy	float. Shift y coordinates by dy (default = 0).
destaggering	Use TRUE to apply destaggering to X and Y coordinates (default = FALSE).
variable	The name of the variable to be imported.
verbose	If TRUE, prints out basic statistics (default = FALSE).

Details

Supported files include those managed by the raster package (as netcdf),

Destaggering is useful for importing data from the SPRAY model and it is not applied by default.

An optional summary output can be printed by setting the verbose parameter.

This function is based on the terra package and it can import any format managed by it.

Value

It returns a dataframe with x, y and z columns.

Examples

## Not run: 
# Import binary (netcdf) file and convert coordinates from km to m,
# without destaggering:
mydata <- importRaster(file = "/path_to_file/filename.nc",
                       k = 1000,
                       destaggering = FALSE)

# Import binary (netcdf) file and convert coordinates from km to m,
# with shift of 100 m in both directions:
mydata <- importRaster(file = "/path_to_file/filename.nc",
                       k = 1000,
                       dx = 100,
                       dy = 100)

## End(Not run)
