SlopeAttribute
Message Summary
message SlopeAttribute
Point attribute. Possible attribute orientation(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.

Properties
| Field | Type | Label | Description | |
|---|---|---|---|---|
slope | uint32 | Slope value in decimal degrees, multiplied by 1000. Logical range -90 to +90 degrees, currently capped to -21 to +21 degrees. | ||
accuracy | string | Accuracy of the slope measurement. BASIC: Derived from basic elevation data. HIGH: Derived from higher resolution data. | ||
segment_identifier | string | An identifier for the referenced segment in the format of domain:system:type:id, for example, "here:cm:segment:532172642". This property is unique in a catalog. | ||
segment_start_offset | double | Values range from [0.0 - 1.0]. Relative to the segment's orientation - not necessarily the overall chain orientation. | ||
segment_end_offset | double | Values range from [0.0 - 1.0]. Relative to the segment's orientation - not necessarily the overall chain orientation. | ||
segment_inverted | bool | The referenced segment is inverted in relation to the chain. | ||
attribute_orientation | string | The attribute's orientation relative to the chain's first-to-last orientation. | ||
multi_segment_id | string | Specifies how an attribute is assigned to a linear chain of one or more Segments. A "linear chain" is a sequence of Segments that connect geometrically from start to end. Segments in a linear chain do not cross one over the other. A linear chain can form a loop in which case the first node of the start segment coincide with the last node of the end segment. In general a multi-segment chain, has an overall first-to-last orientation that is independent of the the first-to-last orientation of each component Segment. Each component Segment in the chain will either have the same first-to-last orientation as the chain, or its orientation will be inverted relative to the chain. It is critical to differentiate the orientation of each component segment from the overall orientation of the chain. For example, it is possible that the first Node of a segment chain is the last Node of that chain's first segment. Likewise, the last Node of the chain can be the first Node of the chain's last segment. The simple case consists of a single segment. In this case the chain and the segment have the same orientation. In the multi-segment case, the chain orientation is independent of the individual segment orientations. | ||
multi_segment_position | int32 | Segment's position in the multi-segment chain. | ||
partition_name | string | Quadkey (HERE tiling) for the current partition. | ||
