next point relation

ordered pair of points (A, B) for which a direct connection exists from A to B along the path of the referenced location
NOTE 1 to entry: In the road network, a direct connection between points A and B exists when point B can be reached from point A via part of the road network, without visiting intermediate points in the location reference.

NOTE 1 to entry: In the road network, a direct connection between points A and B exists when point B can be reached from point A via part of the road network, without visiting intermediate points in the location reference.
This excludes points connected in a GDF graph via a node representing an intersection-not-at-grade. Such points are not considered to be directly connected.

node

zero-dimensional element that is a topological junction of two or more edges, or an end point of an edge
NOTE: A node is created for topologically significant points, such as simple intersections of roads or other linear features including boundaries but also for locations such as electric beacons, kilometre-posts or sensors detecting traffic flows, being significant points specified in a map.

node identifier

identifier assigned to a node
NOTE 1 to entry: A node identifier can be arbitrary, or can be assigned by convention, to ensure that multiple occurrences of the same identifier will not occur within one network or within the universe of similar networks or databases.

parcel

database partitioning unit, corresponding to a certain coverage area and associated with one level and containing data of one or more layers
NOTE 1 to entry: A parcel contains (at least) all nodes with positions enclosed by or located on the outline of its coverage area plus (parts of) all links attached to these nodes.
NOTE 2 to entry: It can be partitioned such that the amount of data…

NOTE 1 to entry: A parcel contains (at least) all nodes with positions enclosed by or located on the outline of its coverage area plus (parts of) all links attached to these nodes.
NOTE 2 to entry: It can be partitioned such that the amount of data of one parcel is nearly the same as that of another.

path

finite, alternating sequence of nodes and edges, such that every arc is immediately preceded and succeeded by the two vertices with which it is incident and in which no vertex is repeated, except (possibly) the first and the last one

place class

attribute of place entity, classifying into highest administrative or geographic division, administrative subdivision, postal, or colloquial (e.g. regions or neighbourhoods)
NOTE: Place class can be partially ordered as “place class A is below place class B“. This does not imply strict or complete containment.

place level

level associated with places of place classification “administrative subdivision”
NOTE: Higher/lower level situations are constituted by the occurrence of a parent/child place relationship between places.

place relationship

bivalent relationship between place entities, constituting the place tree linking parent and child places (“place A is in place B”)
NOTE: Place relationship does not imply strict or complete containment. It is attributed as: address significant, official, postal or useful for reverse geocoding.
