Detailed Description
Used to georeference models.
The SoGeoLocation allows to place a non-georeferenced model at its correct location in geospatial coordinates.
The SoGeoLocation node provides the ability to geo-reference any models. That is, to take an ordinary model, and to specify its geospatial location. This node is a grouping node that can be thought of as a Transform node. However, the GeoLocation node specifies an absolute location, not a relative one, so content developers should not nest GeoLocation nodes within each other. The geoSystem field is used to define the spatial reference frame and is described in 25.2.3 Specifying a spatial reference frame. The geoCoords field should be provided in the format described in 25.2.3 Specifying a spatial reference frame. The geoCoords field can be used to dynamically update the geospatial location of the model.

ACTION BEHAVIOR
- SoGLRenderAction, SoRayPickAction, SoGetBoundingBoxAction, SoCallbackAction, SoGetMatrixAction, SoGetPrimitiveCount
- GC: Earth-fixed Geocentric with respect to the WGS84 ellipsoid.
- GD: Geodetic spatial reference frame.
An optional second string may be used to specify the ellipsoid used. If no ellipsoid is specified, then "WE" is assumed (the WGS84 ellipsoid). - UTM: Universal Transverse Mercator
One further required argument must be supplied for UTM in order to specify the zone number (1..60). This is given in the form "Zn", where n is the zone number. An optional argument of "S" may be supplied in order to specify that the coordinates are in the southern hemisphere (otherwise, northern hemisphere will be assumed). - Inventor/geo/SoGeoLocation.h
