EGM Geoid heights that are good enough for some purposes (maybe yours)

"Good Enough" Geoid

Elixir library that uses pre-generated EGM96-5 data (from GeographicLib's Geoid class) to get geoid heights that are kinda ok, just good enough.

Results should be similar to those that GeoidEval would give you.

Data is currently sampled at 1-degree increments, not great, but good enough. Enhancements for alternate resolutions, datasets and interpolation would be pretty neat!

Installation

Add good_enough_geoid to your list of dependencies in mix.exs and make sure it's started:

def application do
  [applications: [:good_enough_geoid]]
end

def deps do
  [{:good_enough_geoid, "~> 0.0.1"}]
end

Usage

iex> GoodEnoughGeoid.EGM96_5.height(14.013881, 54.140029)
