Extract all geographical coordinates from a netCDF file and convert to simple features object.

Usage

extract_geos(
  nc_obj,
  orig_crs,
  buffer_bbox = NULL,
  crs = NULL,
  name_x = "",
  name_y = ""
)

Arguments

nc_obj: Open netCDF file to retrieve time data from.
orig_crs: Numerical value of the crs used in the netCDF file.
buffer_bbox: Result of sf::st_bbox() or similar to provide a vector of of the buffers. This enables extracting only a small part of the entire netCDF file if required. The order is assumed to be xmin, ymin, xmax and ymax.
crs: Numerical value of the crs to change results into, if different from the original crs.
name_x: Name of the geographical x coordinate to be extracted. If not specified, an attempt will be made to establish this from the netCDF file itself.
name_y: Name of the geographical y coordinate to be extracted. If not specified, an attempt will be made to establish this from the netCDF file itself.

Value

Special features data frame containing the geographic coordinates of the provided netCDF file.

Examples

if (FALSE) { # \dontrun{
 # open the netCDF file
 the_nc_obj <- ncdf4::nc_open("path/to/netCDF/file.nc")

 # extract all spatial points from the netCDF file
 extract_geos(the_nc_obj, crs = 4326)

 # if the names of the spatial coordindates aren't picked up automatically
 extract_geos(the_nc_obj, crs = 4326, name_x = "x", name_y = "y")
} # }
