17、odies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental a

18、nd non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives

19、, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies ca

20、sting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

22、schema that addresses moving features, i.e., features whose locations change over time. This schema includes classes, attributes, associations and operations that provide a common conceptual framework that can be implemented to support various application areas that deal with moving features, includ

23、ing: Location Based Services, Intelligent Transportation Systems, Tracking and navigation (land-based, marine, or space), and Modeling and simulation. The schema specifies mechanisms to describe motion consisting of translation and/or rotation of the feature, but not including deformation of the fea

24、ture. The schema is based on the concept of a one parameter set of geometries that may be viewed as a set of leaves or a set of trajectories, where a leaf represents the geometry of the moving feature at a particular value of the parameter (e.g., a point in time) and a trajectory is a curve that rep

25、resents the path of a point in the geometry of the moving feature as it moves with respect to the parameter.

26、ANDARD INCITS/ISO 19141-20082008 ITIC 2008 - All rights reserved 1Geographic information Schema for moving features 1 Scope This International Standard defines a method to describe the geometry of a feature that moves as a rigid body. Such movement has the following characteristics. a) The feature m

27、oves within any domain composed of spatial objects as specified in ISO 19107. b) The feature may move along a planned route, but it may deviate from the planned route. c) Motion may be influenced by physical forces, such as orbital, gravitational, or inertial forces. d) Motion of a feature may influ

28、ence or be influenced by other features, for example: 1) The moving feature might follow a predefined route (e.g. road), perhaps part of a network, and might change routes at known points (e.g. bus stops, waypoints). 2) Two or more moving features may be “pulled” together or pushed apart (e.g. an ai

29、rplane will be refuelled during flight, a predator detects and tracks a prey, refugee groups join forces). 3) Two or more moving features may be constrained to maintain a given spatial relationship for some period (e.g. tractor and trailer, convoy). This International Standard does not address other

30、 types of change to the feature. Examples of changes that are not adressed include the following: The deformation of features. The succession of either features or their associations. The change of non-spatial attributes of features. The features geometric representation cannot be embedded in a geom

31、etric complex that contains the geometric representations of other features, since this would require the other features representations to be updated as the feature moves. Because this International Standard is concerned with the geometric description of feature movement, it does not specify a mech

32、anism for describing feature motion in terms of geographic identifiers. This is done, in part, in ISO 19133. 2 Conformance 2.1 Conformance classes 2.1.1 Introduction This International Standard specifies four conformance classes (Table 1). They are differentiated on the basis of two criteria: purpos

33、e and level of complexity. Copyright American National Standards Institute Provided by IHS under license with ANSI Not for ResaleNo reproduction or networking permitted without license from IHS-,-,-INCITS/ISO 19141-20082008 2 ITIC 2008 - All rights reserved2.1.2 Purpose This International Standard m

34、ay be used in support of data transfer. Operations defined for objects are irrelevant to data transfer, which requires only descriptions of the state of the objects at the time of transfer. Thus, two conformance classes require only the implementation of attributes and associations of the classes sp

35、ecified in the schema. The other two conformance classes support the object-oriented implementation of systems or interfaces; they require implementation of operations as well as implementation of attributes and associations. 2.1.3 Complexity Many applications do not need a complete description of t

36、he geometry of a feature and its orientation at any point in time. Their requirements are satisfied by describing the movement of a single reference point on the feature using its trajectory as specified in Clause 6. One pair of conformance classes supports these simple applications. Other applicati

37、ons need knowledge of the positions at each time of all points or a significant subset of the points on a moving feature. They require the full description provided by the prism geometry specified in Clause 7. Table 1 Conformance classes Purpose Complexity Data Transfer Data with operations Trajecto

42、esentation, using a local origin and local ordinate vectors, of a geometric object at a given reference time NOTE 1 A rigid geometric object may undergo translation or rotation, but remains congruent with its base representation. NOTE 2 The local origin and ordinate vectors establish an engineering

43、coordinate reference system (ISO 19111), also called a local frame or a local Euclidean coordinate system. 4.1.2 curve 1-dimensional geometric primitive, representing the continuous image of a line ISO 19107:2003, definition 4.23 NOTE The boundary of a curve is the set of points at either end of the

44、 curve. If the curve is a cycle, the two ends are identical, and the curve (if topologically closed) is considered to not have a boundary. The first point is called the start point, and the last is the end point. Connectivity of the curve is guaranteed by the “continuous image of a line“ clause. A t

45、opological theorem states that a continuous image of a connected set is connected. 4.1.3 design coordinate reference system engineering coordinate reference system in which the base representation of a moving object is specified 4.1.4 feature abstraction of real world phenomena ISO 19101:2002, defin
