Extract and store WMS as a geo-referenced TIFF

Description

This function interacts with deprecated Copernicus Marine Services. It will become .Defunct() in future versions. Extract and store imagery from a Copernicus WMS as a geo-referenced TIFF.

Usage

copernicus_wms2geotiff(
  product,
  layer,
  variable,
  region,
  destination,
  width,
  height
)

Arguments

product	An identifier (type character) of the desired Copernicus marine product. Can be obtained with copernicus_products_list.
layer	The name of a desired layer within a product (type character). Can be obtained with copernicus_product_details.
variable	The name of a desired variable in a specific layer of a product (type character). Can be obtained with copernicus_product_details.
region	Specification of the bounding box as a vector of numerics WGS84 lat and lon coordinates. Should be in the order of: xmin, ymin, xmax, ymax.
destination	File name for the geo-referenced TIFF.
width	Width in pixels of the TIFF image.
height	Height in pixels of the TIFF image.

Details

A Web Map Service (WMS) cannot be plotted directly (base, ggplot2 and/or lattice). For that purpose you need to extract and download a specific region in a format that can be handled by plots. You can use this function to store a subset of a WMS map as a geo-referenced TIFF file.

Value

Stores the file as destination and returns invisible NULL

Note

WMS functions don't work on systems that don't support GDAL utils
