The work of preparing Internation

    15、al 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 and non-governmental, in liaison with ISO,

    16、 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, Part 2. The main task of technical comm

    17、ittees 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 casting a vote. Attention is drawn to the p

    19、08 - All rights reservedIntroduction This International Standard specifies a conceptual 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

    20、 implemented to support various application areas that deal with moving features, including: 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

    21、 of translation and/or rotation of the feature, but not including deformation of the feature. 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 partic

    22、ular value of the parameter (e.g., a point in time) and a trajectory is a curve that represents the path of a point in the geometry of the moving feature as it moves with respect to the parameter. AMERICAN NATIONAL STANDARD INCITS/ISO 19141-20082008 ITIC 2008 - All rights reserved 1Geographic inform

    23、ation 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 moves within any domain composed of spatial objects as specified in ISO 19107. b) Th

    24、e 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 influence or be influenced by other features, for example: 1) The moving feature might f

    25、ollow 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 airplane will be refuelled during flight, a predator detects and tracks a prey, refug

    26、ee 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 types of change to the feature. Examples of changes that are not adressed include

    27、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 geometric complex that contains the geometric representations of other features, since

    28、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 mechanism for describing feature motion in terms of geographic identifiers. This is don

    29、e, 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: purpose and level of complexity. INCITS/ISO 19141-20082008 2 ITIC 2008 - All rights reser

    30、ved2.1.2 Purpose This International Standard may 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

    31、 attributes and associations of the classes specified 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 applic

    32、ations do not need a complete description of the 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 suppo

    33、rts these simple applications. Other applications 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 Complexi
