Results for area 6.4 Digital map database
structured set of digital and alphanumeric data portraying geographic locations and relationships of spatial features
Note 1 to entry: Typically, such structures represent, but are not limited to, the digital form of hard copy maps. For example, drawings can be imported into a Geographic Information System (GIS) and considered as a form of digital map.
API ISO context specification interface and set of function calls between application software and data access libraries of vehicle navigation systems
data model package that is composed of Background Imagery, Map Data Background, Cartographic Feature Type, Figure Element and Picture file entity for displaying Map
collection of related data records having a homogeneous structure
data model entity that provides background images upon which the road network of an area may be displayed
data model entity that provides the location and shape of road side features such as a toll gate, or a fixed Road Side ITS station
identifier that is uniquely assigned to a link
NOTE 1 to entry: A link identifier can be arbitrary or can be assigned by convention, to ensure that no multiple occurrences of the same identifier will be used within one instance of a network or map database.
data model entity that provides cartographic feature by their type (Symbol, Point, Polyline and Polygon)
record that logically precedes the data records and contains control parameters, data definition and documentation necessary to interpret companion data records
data model entity that provides warning information about an approaching potential hazard on the Road Elements that may require some action by the driver of a vehicle
database partitioning unit corresponding to a certain coverage area, associated with one level and containing data of one or more layers
NOTE 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; it can be partitioned so that the amount of data of a parcel may be nearly the same as that of another.
data model entity that provides the detailed information of Special Route such as the ordered sequence of Link and Intersection lists, length of route and fee of toll road
Named sequences of characters from the DNF character set which are used to form the DNF notation
data model entity that provides the guidance information for a path which is composed of the entrance Link and the exit Link connected to an Intersection
data model entity that provides the name of a geographic area feature for each Link connected to an intersection
application category that deals with the task of expressing a real world position in terms of the data representation
NOTE Address location is one of the six application categories supported by the API.
data model entity that provides the shape data of a cartographic feature for displaying a map
translating a location reference to a specific object in a given map database to attempt recognition of the same identified object in both the sender’s and the receiver’s map database
NOTE 1 to entry: Matching is seen as a subsequent part to the method of decoding a location reference adhering to the defined LRM.
data model entity for a topological junction of two or more links or end bounding a link
NOTE 1 to entry: A link stores the coordinate value of the corresponding GDF junction.
data model entity that provides the time or monetary cost between the entrance Link and exit Link of Intersection for calculating route
type consisting of all possible floating-point numbers plus the two values +∞ and -∞
NOTE The floating-point type is a subset of the real type in ASN.1. The real type accommodates bases other than 10.
data model entity that provides the Links in the Intersection used for determining the path through an intersection
reference source of sufficient Completeness and/or accuracy that may be substituted for Field verification when measuring the Completeness and/or accuracy of map database Features, Attributes, or properties
data model entity that provides the shape of the Intersection Link for displaying a path
implementation dependent construct that consists of an identifiable collection of one or more related Fields
data model entity that provides the name of an Intersection. An Intersection may have one or more names corresponding to the direction of entering into the intersection
specified part of a record containing a unit of data which may be a data element or a data item
data model entity that provides the shape geometry of the lane
set of characters used in the DNF notation
collection of related Datasets (logical sub-division) and, if applicable, Volumes (physical sub-division)
data model entity that provides the time or monetary cost of the Link for calculating route
spatial subset of a Dataset
NOTE The coverage area of a map sheet, confined by geographic coordinates, can be considered a Section.
data model entity that provides a background image of the Road Element and the intersection upon which guidance information is displayed
data model entity that provides map database features for background display
data model entity that provides a representative point within a Place
data model entity that provides information such as the length, height and slope of bridges and tunnels
data model entity that provides the shape geometry of the Road Element for displaying Road and Positioning
data model entity that provides the shape of painted markings on roads such as lane markings these may be used for display purposes
data model entity that provides the detailed text of the road signage on the Road Element
NOTE 1 to entry: Route Guidance is one of the six application categories elements and joining two intersections, serving as the smallest independent unit of a road network at GDF level 2.
data model entity that provides a representative point of a Service and POI
data model entity that provides the geocoded Street Address of the Road Element
data model entity that provides the traffic restrictions such as one way or turn restrictions for route calculation purposes
