SlopeAttribute
Message Summary
message SlopeAttribute
Anchor type: Point. Possible SegmentAnchor Direction(s): Forward
Slope is the angle of inclination at the point indicating the angle of inclination from this point towards the segment. To represent a segment's slope exiting/entering an intersection, the point will be at 0.0 or 1.0 of the segment.
Slope indicates the angle of slope at a Shape Point as traversed from start node to the end node, or at a Node indicating the angle of slope from this Node toward the same segment, given in Decimal Degrees x 103.

Properties
| Field | Type | Label | Description | |
|---|---|---|---|---|
segment_anchor_index | uint32 | repeated | Indices of all segment anchors to which this attribute applies. 0-based index references to segment_anchor in AdasPartition. Never empty. | |
slope | sint32 | Slope value in decimal degrees, multiplied by 1000. Logical range -90 to +90 degrees, currently capped to -21 to +21 degrees. 21 degree slope is 38.38 percent gradient [tan(21 degrees)]. Hence the capping of slope values(At present, worlds steepest road is below 38 percent gradient). | ||
