osgEarth Sample

This demonstrates how to use the OGR feature driver to define inline feature geometry.

You can define an inline geometry in WKT format.
* See: http://en.wikipedia.org/wiki/Well-known_text#Geometric_objects

Notice the different interpolation types for each layer, and the difference in the
display. The options are:
 "rhumb_line" - maintains a constant bearing between two points (default), or
 "great_circle" - takes the shortest elliptical distance between two points.
