float x direction to second point
float y direction to second point
float x offset to third point
float y offset to third point

The x and y coordinates are given as offset from the middle of the LOD13 square (range -0.5 till 0.5).

Vegetation

For each vegetation rectange the following data is specified:

float x position of first point
float y position of first point
float x offset to third point
float y offset to third point

The x and y coordinates are given as offset from the middle of the LOD13 square (range -0.5 till 0.5).
