SRTM is a small library that provides a simple interface to query locations on
the earth for elevation data from the NASA Shuttle Radar Topography Mission
(SRTM).

## Examples

```elixir
{:ok, client} = SRTM.Client.new("./cache")
#=> {:ok, %SRTM.Client{}}

{:ok, elevation, client} = SRTM.get_elevation(client, 36.455556, -116.866667)
#=> {:ok, -51, %SRTM.Client{}}
```

See the [documentation](https://hexdocs.pm/srtm) for further
information on configuration.
