Ruby GIS - Converting NAD83 to WGS84

Question

I'm in the processing of developing a GIS component for our product and I have the need to convert NAD83 to WGS84.

Does anyone know of any Ruby libraries that are available that do this? Or experience with anything that might do this? I had previously done this using a library in .Net/C#, but so far I haven't had much luck tracking down an equivalent library.

I've already got the GeoRuby gem installed, but that doesn't seem to cover this type of work.

Answer 1

Proj4rb is a Ruby binding for Proj.4, which is the de facto library when it comes to converting between arbitrary projections and datums.
