The grade level of a segment represents the relative altitude of the segment at a particular point along the segment. This level is in relation to other segments at the same point. For example, you might have a freeway at level = 0 and an overpass at level = 2. Vertical segments are represented by a polyline containing only 1 vertex and exactly two grade_level in segment.proto whose indices are 0. grade_level(0) represents the relative height at the start point of the segments, and grade_level(1) represents the one at the end point.
