Road Surface Marking Classification values.
feature RoadSurfaceMarking extends MomFeature
Representation of a unique, aggregated physical RoadSurfaceMarking.
|geometry||Point||3D center point of the RoadSurfaceMarking.|
|properties||RoadSurfaceMarkingProperties||Represent the properties for RoadSurfaceMarking|
|referencePoint||Point||optional||This is the location of this feature, collapsed to a single point.This is for any application where an approximate, but deterministic and consistent, location is useful. Oneexample is deciding where to "anchor" a feature within a tiled map database.Any |
|nonSpatialPartitionKey||string||optional||The partition id for a generically partitioned feature.Generically partitioned features fall into two categories:1. Features that have a spatial component but may not make sense to partition based on that geometry.2. Features that don't have a strong spatial component.How keys will be assigned and what value ranges will be used are not specified.Examples of generically partitioned features are admin, zone, postal, phonetics, metadata, etc.|
|atMostOneDefinedProperty||(is-empty(.referencePoint)||is-empty(.nonSpatialPartitionKey))||At most one of |
|pointDefined||non-empty(.referencePoint)||Ensures that the reference-point is defined.|
part RoadSurfaceMarkingProperties extends Common
Represent the properties like width, length, orientation and classificationEstimate for RoadSurfaceMarking
|@ns:com:here:mom:rmob||string||optional||Currently not specified - may be specified by each Feature individually in future|
|featureType||FeatureType||optional||Deprecated. This property is redundant to MomFeature.momType and should not be used.MOM clients before 2.6 release had this deprecated property set to required, soif data needs to be JSON schema validated by clients before 2.6 this property must beset by the writer.|
|isoCountryCode||Country||optional||Deprecated. This indicates which country a Feature is in, with a couple caveats.- It may be unknown ("NONE" is a valid value, in addition to "UNDEFINED" like all MOM enums) simply because the writer has not tried to figure it out or has otherwise not had the means to do so.- It may be outright incorrect or a simplification of reality, specifically when a Feature is close to a country border or in a disputed area (e.g., two or more countries claim the same area).In all cases, writers and readers of this data should understand that the semantics of this property must beagreed upon (if it is used at all). The preferred method of relating a Feature to a Country is through a(direct or transitive) Reference from the Feature to an Admin.|
|@ns:com:here:xyz||Xyz||optional||Generic Data Hub namespace|
|extensionOSM||MomOsm||optional||Optional extension for OSM (Open Street Map) metadata,in case the object came from OSM|
|@ns:com:here:groundTruth||GroundTruth||optional||Ground truth namespace|
|confidence||ConfidenceData||optional||Confidence of a feature, optional only for the featuresthat are not participating in Quality Index.|
|widthCm||CentimeterEstimate||optional||The width of the marking is measured along the Y axis.|
|lengthCm||CentimeterEstimate||optional||The length of the marking is measured along the Z axis in the local coordinate system.|
|orientation||OrientationEstimate||optional||Road Surface Marking internal coordinate system (X, Y, Z)X is defined as normal to the road surface.Z is primarily defined as being the direction from which the characters or figures are oriented "right-side-up".Some markings (arrows and diamonds for example) exhibit some degree of rotational degeneracy.When this is the case the "up" direction should point in the direction of the arrow when only the tail istaken into account.For diamonds or other highly degenerate objects then up should be along the longest axis of the boundingrectangle.This will lead to at least a two fold degeneracy in the definition, but for such markings the orientationdoesn't convey any information any way so if it is wrong we haven't lost anything.Y is defined as the cross-product of Z and X.The orientation quaternion represents a rotation from the XYZ coordinate frame described above to the ENUtangent coordinate frame defined at the geometry point of the marking.|
