More examples of when to use Flatten Elevation.

Large bridge spans that are a significant height over the water often have an elevation dip as the scanning satellites recorded the ground rather than the bridge itself.

Here the dip is normalized to something closer resembling the actual height of the bridge rather than the river below.

Going up a large hill, this route passes through a short tunnel causing an elevation spike from the map data. I’ve selected the spike where it starts and ends.

Here’s the tunnel after Flatten Elevation. The elevation spike is now gone and the metrics have updated automatically.
