Examples

Standard Bridge

Grid Interpolated LIDAR

1/(0.03+maximum_gradient)

0.4/(0.03+average_gradient)

0.5*maximum_gradient_of_perpendicular

Highway Interchange

Grid Interpolated LIDAR

1/(0.03+maximum_gradient)

0.4/(0.03+average_gradient)

0.5*maximum_gradient_of_perpendicular

Missing

• Variance of gradient (borked)
• Combination calculations (untuned parameters)
• Quantitative comparison with hand labeled bridges
