1.2. Terms and Definitions#
- Attribute
Characteristic of a feature. For example, number of lanes or pavement status.
- Class
Description of a set of objects that share the same attributes, operations, methods, relationships, and semantics. A class does not always have an associated geometry (e.g. address range class).
- Dataset
Data collection identifiable for a Canadian province or territory.
- Entity
Digital representation of a real world phenomenon. For example, the digital representation of King Street is an entity.
- Ferry Connection
The average route a ferryboat takes when transporting vehicles between two fixed locations on the Road Network. Two Junctions always bound a Ferry Connection.
- National Vector Data
Several layers of vector data, referred to as National Vector Data (NVD), will share the same specification. The National Road Network (NRN) and National Hydrographic Network (NHN) are examples of NVD.
- Network Linear Element
Abstract class of a Road Element and Ferry Connection.
- Object
An object is an instance of a class.
- Road Element
A road is a linear section of the earth designed for or the result of vehicular movement. A Road Element is the representation of a road between Junctions. A Road Element is always bounded by two Junctions. A Road Element is composed of one or more than one contiguous Road Segments.
- Segment
Portion of a Network Linear Element that has a common set of defined characteristics (attributes).
- Universal Unique Identifier
The definition and method used for the generation of a Universal Unique Identifier (UUID) is defined in the document Identification Rules.
