This International Standard specifies a conceptual schema that addresses moving features, i.e., features
5、whose locations change over time. On the basis of this schema operations that provide a common conceptual framework can be implemented to support various application areas that deal with moving features, including: Location Based Services, Intelligent Transportation Systems, Tracking and navigation
6、(land-based, marine, or space), and Modeling and simulation. The schema specifies mechanisms to describe translation and/or rotation motions of rigid bodies.

24、 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) The feature may move along a planned route, but it may deviate from th
25、e 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 follow a predefined route (e.g. road), perhaps part of a network, and
26、 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, refugee groups join forces). 3) Two or more moving features may be constr
27、ained 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 the following: The deformation of features. The succession of either
28、 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 this would require the other features representations to be updated
29、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 done, in part, in ISO 19133. 2 Conformance 2.1 Conformance classes 2.1.
30、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. 5DIN EN ISO 19141:2009-12 EN ISO 19141:2009 (E) 2.1.2 Purpose This International Standard may be used in support of data tra
31、nsfer. 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 specified in the schema. The other
32、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 the geometry of a feature and its
33、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 applications need knowledge of the positio
34、ns 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.

39、presentation. NOTE 2 The local origin and ordinate vectors establish an engineering 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, de
40、finition 4.23 NOTE The boundary of a curve is the set of points at either end of the 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. Con
41、nectivity of the curve is guaranteed by the “continuous image of a line“ clause. A topological 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
42、is specified 4.1.4 feature abstraction of real world phenomena ISO 19101:2002, definition 4.11 NOTE A feature may occur as a type or an instance. Feature type or feature instance shall be used when only one is meant. 4.1.5 feature association relationship that links instances of one feature type wit
43、h instances of the same or a different feature type ISO 19110:2004, definition 4.2 NOTE Feature associations include aggregation of features. 4.1.6 feature attribute characteristic of a feature ISO 19101:2002, definition 4.12 4.1.7 feature operation operation that every instance of a feature type ma
