Scope The Location Referencing Message Specification (LRMS) standardizes location referencing for ITS applications that require the communication of spatial data references between databas

23、es. ITS databases may reside in central sites, vehicles, or devices on or off roads or other transportation links. The LRMS is applicable to both homogeneous (same database) and mixed database environments that may be implemented on wireless or landline networks. While developed for ITS applications

24、, the LRMS may be used for non-ITS applications as well within the field of geographic information processing. 2.

32、e. 3.1 Definitions 3.1.1 Accuracy: The closeness of results of observations, computations, or estimates to the true values or the values accepted as being true. (NIST, 1992) With regards to a digital base map, accuracy refers to how close observation or computational estimates of the position of map

33、ped features are to true ground position. (MnDOT, 1993) 3.1.2 Administrative Area: For administrative purposes, the territory of a country may be divided into regions that have further subdivisions, forming a hierarchy of political units. Some countries have Administrative Areas that are not part of

34、 such a hierarchy. (GDF 4.0) 3.1.3 Altitude: Elevation above or below a reference datum, as defined in FIPSPUB 70-1; the z-value in a spatial address. See also elevation. 3.1.4 Area: A generic term for a bounded, continuous, two-dimensional object that may or may not include its boundary. (NIST, 199

35、2) 3.1.5 Attribute: A defined characteristic of an entity type. (NIST, 1992) Within a digital map database, attribute values of the digital object representation of an entity are typically alpha-numeric data within well-defined ranges. 3.1.6 Complex Intersection: The intersection of roadways involvi

36、ng offsets, central medians or some combination of offsets and central medians that can generate multiple nodes for representation. (Schuman, 1993) 3.1.7 Coordinate: A pair of numbers expressing horizontal distances along orthogonal axes; alternatively, a triplet of numbers measuring horizontal and

37、vertical distances. (NIST, 1992) 3.1.8 Coordinate system: A reference system for the unique definition of a location of a point in n-dimensional space. (Krzanowski et al, 1993) 3.1.9 Data Element: Some single unit of information of interest (such as a fact, proposition, observation, etc.) about some

38、 (entity) class of interest (e.g., a person, place, process, property, concept, association, state, event). (ISO/DIS 14817) 4SAE PublicationsAvailable from SAE, 400 Commonwealth Drive, Warrendale, PA 15096-0001. SAE J2266 Issued OCT2004 - 7 - 3.1.10 Data Frame: Grouping of data elements primarily fo

39、r the purpose of referring to the group with a single name, and thereby efficiently reusing groups of data elements that commonly appear together (as an ASN.1 Sequence, Sequence Of, Set, Set Of or Choice) in a message body specification. (ISO/DIS 14817) 3.1.11 Datum: A set of parameters and control

40、points used to accurately define the three-dimensional shape of the Earth (e.g. as an ellipsoid). The corresponding datum is the basis for a planar coordinate system. (MnDOT 1993) 3.1.12 Easting: An east (X-axis) offset of a location within a grid cell or UTM cell with respect to an origin. 3.1.13 G

41、eographic Coordinates: The quantities of latitude and longitude (and, sometimes, altitude) which define the position of a point on the Earth with respect to the reference spheroid or ellipsoid. (MnDOT 1993) 3.1.14 Grid: A set of grid cells forming a regular, or nearly regular, tessellation of a surf

42、ace. The tessellation is regular if formed by repeating the pattern of a regular polygon, such as a square, equilateral triangle, or regular hexagon. The tessellation is nearly regular if formed by repeating the pattern of an “almost“ regular polygon such as a rectangle, non-square parallelogram, or

43、 non-equilateral triangle. 3.1.15 Grid Cell: A two-dimensional object that represents the smallest nondivisible element of a grid. (NIST, 1992) 3.1.16 Grid Coordinates: Two distances which fix the position of a point on a grid. The perpendicular distance to the point from the y-axis is called the x

44、coordinate while the perpendicular distance to the point from the x-axis is called the y coordinate. (MnDOT 1993) 3.1.17 Grid Resolution: Distance between neighboring grid nodes. (Krzanowski et al, 1993) 3.1.18 Junction: A Feature that bounds Transportation Elements (ref. 3.1.45). A Junction Feature

45、 represents the physical connection between its adjoining Transportation Elements. 3.1.19 Line: A linear object composed of one or more connected line segments formed by a series of points. Commonly, a line represents such geographic entities as roads, rivers and shorelines. (Krzanowski et al, 1993)

46、 A one-dimensional object. (NIST, 1992) 3.1.20 Line Segment: A direct line between two points. (NIST, 1992) 3.1.21 Linear Object: A continuous one-dimensional object composed of a sequence of one or more line segments, each point of which bounds a maximum of two line segments. 3.1.22 Linear Referenc

48、nates (shape points) to better represent the shape of curved features. (Schuman, 1993) A link may be directed by ordering its nodes. 3.1.24 Message: Grouping of data elements and/or data frames, as well as associated message metadata, that is used to convey a complete unit of information. (ISO/DIS 1

49、4817) SAE J2266 Issued OCT2004 - 8 - 3.1.25 Message Set: A collection of messages (see 3.1.24) for an application area. 3.1.26 Metadata: Data describing a set of data, for example its quality, lineage, format, and intended or suitable use. 3.1.27 Milepost: A reference point along the linear objects of a road network used in a linear referencing scheme.
