4.1

Address Location

application category that deals with the task of expressing a real-world position in terms of the PSF data representation

4.2

application category

basic sub-function within the set of functionality for cooperative ITS support

Note 1 to entry: This International Standard identifies eight application categories: Positioning, Route Planning, Route Guidance, Map Display, Address Location, Services and POI Information Access, cooperative ITS including Driving support, Multi-Modal Travel.

4.3

display point

0-dimensional type of cartographic feature

4.4

geocoding

determination of a link or node based on address information describing and/or naming a location

4.5

intersection

GDF level 2 representation of a crossing which bounds a road or a ferry as a complex feature composed of one or more GDF level 1 junctions, Road Elements and enclosed traffic areas

4.6

itinerary

plan of a journey, including the route and the places visited

4.7

junction

navigable feature which is either a named GDF junction or named GDF intersection, and that relates a named navigable feature to a set of links and nodes and a place

4.8

landmark

point, line or area feature that can be used to clarify the directions generated to describe a route

Note 1 to entry: It can be associated to a node or a link.

Note 2 to entry: A landmark cannot be in the Services, Administrative Areas, or Public Transportation Feature themes of the GDF; however a facility in which a service is located can be a landmark.

4.9

layer

sub-set of map data resulting from a subdivision of data of the same coverage area based on contents (similar to ISO 14825 GDF layer) and which is typically related to one or only a few of the application categories

4.10

level

sub-set of map data resulting from classification of data of the same semantic contents based on the level of details/density, related to the concept of different map scales

Note 1 to entry: Level 0 is considered the lowest level (greatest detail); higher levels are numbered level 1, level 2, etc.

4.11

link

directed topological connection between two nodes, composed of an ordered sequence of one or more segments and represented by an ordered sequence of zero or more shape points

4.12

Local Dynamic Map

conceptual data store which is embedded in an ITS station and which contains topographical, positional and status information

4.13

Map Display

application category that deals with graphical information presentation

4.14

Multilink

ordered aggregation of links which are at the same level, connected in sequence, share the same functional classification, form of way, direction of travel, and perhaps additional PSF-builder-specified characteristics, such that each link is contained in exactly one Multilink

4.15

Multi-Modal Travel Service

application category that provides information on a trip from an origin to a destination using alternative modes of transportation or a combination of transport modes for one trip

Note 1 to entry: This service may include navigation.

4.16

Multi-Modal Travel Support

application function for Multi-Modal Travel Service

4.17

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 of one parcel is nearly the same as that of another.

4.18

place

named area which can be used as part of Address Location

4.19

Point of Interest

POI

destination and/or site of interest to travellers, usually non-commercial by nature

4.20

polygon

2-dimensional type of cartographic feature

4.21

polyline

1-dimensional type of cartographic feature

4.22

Positioning

application category that deals with the determination of vehicle location and map-matching

4.23

position-on-the-link

position on the road or road side used to identify the access point between the road network and entrance or exit of facilities such as station, bus stop and building

4.24

rectangle

unit of geographic space, defined by two parallels of min/max latitude and by two meridians of min/max longitude, that represents the coverage area of the map data enclosed by or located on the outline of the rectangle

4.25

regular parcel

parcel shaped like a rectangle

Note 1 to entry: Regular parcels on the same generalization level are not intended to overlap.

4.26

reverse geocoding

determination of the address description of a link or node (i.e. determination of an upwards path across the place tree)

4.27

road

GDF level 2 feature composed of one, many or no Road Elements and joining two Intersections, serving as the smallest independent unit of a road network at GDF level 2

4.28

route

ordered list of route links, or of stop points respectively, defining a single path through the transport network, with a direction

4.29

Route Guidance

application category that deals with the generation of graphical, textual, and/or audio instructions for following a planned route

4.30

route link

oriented link between two route Points defining a unique path through the transport network

4.31

Route Planning

application category that deals with the determination of routes between specified points

4.32

segment

straight section of a link connecting either two successive shape points, or a shape point and a node, or two nodes in case the link does not contain shape points

4.33

service

data model entity for a commercial activity of interest to travellers as a destination and/or orientation that is associated with Road Element(s) or place(s), by which it can be accessed

Note 1 to entry: Service is further described by attributes including (at least) name and type; it can be associated with other services by parent/child relationships (many to many).

Note 2 to entry: Service is used synonymously with POI within the logical data model.

4.34
