Greetings,

Is there an EGM96 Geoid calculator out there in Ruby? See this for  
example:

> **[NGA Geomatics - WGS 84](https://earth-info.nga.mil/index.php?dir=wgs84&action=wgs84)**
>
> MISSION: Develop, maintain, and enhance the World Geodetic System 1984, the reference frame upon which all geospatial-intelligence is based.

Does GeoRuby do this, and I just couldn’t find the right method name?

Regards,

Dan
