osgEarth Sample

This example demonstrates how to set a particular datum for a geocentric map.
By default, a geocentric map will use a WGS84 datum. Use the "profile" tag
to specify a different one is so desired. The contents of the "srs" tag can be
any SRS initialization string (like PROJ4 or WKT).

This example renders a NAD27 globe instead of a WGS84 globe.

See this site for SRS codes and PROJ4 initialization strings:
