I there a convenient way to calculate the distance of a point from the
coast in NCL, given a projection? I know the function gc_latlon will
give me the great circle distance between two points, or two arrays. So
I expect the answer is to extract the coordinates from the coastline,
convert to a an array variable, and then use gc_latlon to calculate the
distance between the specified locations array and the coastline array.
Is this the way to proceed, or is there a distance from coast function,

Best fishes
