Detailed Description

VSG extension Geographic coordinates node.

The SoGeoCoordinate node allows applications to build geometry using geographic coordinates

The SoGeoCoordinate node specifies a list of coordinates in a spatial reference frame. It can be used in place of an SoCoordinate3 node. The geoSystem field is used to define the spatial reference frame and is described in 25.2.3 Specifying a spatial reference frame. The point array is used to contain the actual geospatial coordinates and should be provided in a format consistent with that specified for the particular geoSystem (see above). The geospatial coordinates are transparently transformed into a geocentric, curved-earth representation. For example, this would allow a geographer to create a world where all coordinates are specified in terms of latitude, longitude, and elevation.

Member Data Documentation

◆ geoSystem

SoMFString SoGeoCoordinate::geoSystem

Defines the spatial reference frame.


Valid values are:

  • 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 "Z<n>", 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).
