NOTE 2: A district may be a commonly known name for an area, or it may be an area assigned for postal or administrative purposes. A district or sector may be one of several areas with a similar naming structure that may include a type and indicator structure. NOTE 3: “District” is used by some countries for high level administrative divisions that are mapped to element region while element district is reserved for sub-divisions of town. For districtTerritory (that can be seen in the AddressLineTypeEnum): Element specifying the geographic or administrative area of the country in which the town is situated. NOTE 1: This element appears in the delivery point specification segment. It comprises subelements for levels of region, each with positions, with a type and indicator for each level and position. NOTE 2: Regions are generally related to administrative rather than to postal geography. Examples include French Departments, German Länder, British Counties and American States. 11.2.5 Describing Locations 11.2.5.1 Introduction on Location, and Location Referencing Nearly all parking and mobility applications need a description of the location of features (physical objects, restrictions, events, etc.) in a spatial context, both in absolute relationship to the surface of the Earth, and in relation to other features. One definition of the term "location referencing” or geolocation would be "description of an identifiable geographic place"; others include "label(s) which is assigned to a location", or "means to provide information that allows a system to identify accurately a location". Many location references may be applicable for the features within a hierarchy. Some examples include: • An x, y coordinate (longitude, latitude) that defines the notional position of the Place as a whole for coarse representation on a small-scale map of, say, the Place within a Campus; • A bounded polygon which represents the physical extent of a Place; • An x, y coordinate (longitude, latitude) that marks the location of each Vehicular Access to support SatNav navigation services for routing to the entrances of a Place; • An x, y coordinate (longitude, latitude) of a specific parking space to support find-my-car applications. The UML classes, attributes and relationship defined below are very largely drawn from existing recognised standards published by ISO and/or CEN. In some cases, to make these approaches globally applicable some concepts have been extended.
