\class SoGeoLocation SoGeoLocation.h Inventor/nodes/SoGeoLocation.h
\brief The SoGeoLocation class is used to georeference the following nodes.
\ingroup nodes
<b>FILE FORMAT/DEFAULTS:</b>
\code
GeoLocation {
geoSystem ["GD", "WE"]
geoCoords 0 0 0
}
\endcode
This node specifies an absolute geographic coordinate system for the
following nodes. When rendering (or applying other actions), Coin
will add a transformation which transforms the geometry into the
SoGeoOrigin coordinate system. All objects will be rotated to make
the local Z axis point up from the ground (at the specified
geo-location), the Y axis will point towards the north pole, and the
X axis is found using the right hand rule.
\sa SoGeoOrigin
\since Coin 2.5
