latlon_to_epsg3031(df, reg=False, input_coord_names=None, output_coord_names=('easting', 'northing'))

Convert coordinates from EPSG:4326 WGS84 in decimal degrees to EPSG:3031 Antarctic Polar Stereographic in meters.

Parameters:

• df (DataFrame | ndarray[tuple[Any, ...], dtype[Any]]) – input dataframe with latitude and longitude columns

• reg (bool) – if true, returns a GMT formatted region string, by default False

• input_coord_names (tuple[str, str] | None) – set names for input coordinate columns, by default (“lon”, “lat”)

• output_coord_names (tuple[str, str]) – set names for output coordinate columns, by default (“easting”, “northing”)

Returns:

Updated dataframe with new easting and northing columns or numpy.ndarray in format [xmin, xmax, ymin, ymax]

Return type:

DataFrame | ndarray[tuple[Any, ...], dtype[Any]]
