Creates continental outlines from model orography data.
procedure paleo_outline ( oro [*][*] : numeric, lat [*] : numeric, lon [*] : numeric, landvalue  : float, basename : string ) return_val
A two-dimensional array of orography values. Dimensions are lat x lon.lat
A one-dimensional array of latitudes. Must be the same size as the leftmost dimension of oro.lon
A one-dimensional array of longitudes. Must be the same size as the rightmost dimension of oro.landvalue
A scalar float that indicates the value of land in oro.basename
A string equal to the base name for the two map files which will be created (i.e. "jurassic"). This can include the path where the files should be created (i.e. "./eocene").
This procedure creates continental outlines from model orography data for use in paleo-geographic plots, and writes the data to two files which can then be accessed via the mpDataSetName resource to draw the new outlines. The two files will be called basename.lines and basename.names.
Once these files are created, you can put them in the directory $NCARG_ROOT/lib/ncarg/database, and then you can load them using the mpDataSetName resource, and you don't have to indicate the path to the files or regenerate the files every time.
