I'm still working on understanding the code. First, you have
point_list geod_light_nodes
= calc_elevations( root, light_nodes.get_node_list(), 0.5 );
That means that the base elevation for each light is already 0.5m
above the runway. Does FlightGear have ssg do further elevation
adjustments at runtime?
All the best,
David
