28、All rights reserved vIntroduction This part of ISO 19125 describes the common architecture for simple feature geometry. The simple feature geometry object model is Distributed Computing Platform neutral and uses UML notation. The base Geometry class has subclasses for Point, Curve, Surface and Geome

29、tryCollection. Each geometric object is associated with a Spatial Reference System, which describes the coordinate space in which the geometric object is defined. The extended Geometry model has specialized 0, 1 and 2-dimensional collection classes named MultiPoint, MultiLineString and MultiPolygon

30、for modelling geometries corresponding to collections of Points, LineStrings and Polygons, respectively. MultiCurve and MultiSurface are introduced as abstract superclasses that generalize the collection interfaces to handle Curves and Surfaces. The attributes, methods and assertions for each Geomet

31、ry class are described in Figure 1 in 6.1.1. In describing methods, this is used to refer to the receiver of the method (the object being messaged). The SFA COM function “signatures” may use a different notation from SFA SQL. COM notation is more familiar for COM programmers. However, UML notation i

32、s used throughout this part of ISO 19125. There may also be methods used in this International Standard that differ from one part to another. Where this is the case, the differences are shown within the part. This part of ISO 19125 implements a profile of the spatial schema described in ISO 19107:20

33、03, Geographic information Spatial schema. Annex A provides a detailed mapping of the schema in this part of ISO 19125 with the schema described in ISO 19107:2003. 4EN ISO 19125-1:2006 (E) 1 Scope This part of ISO 19125 establishes a common architecture and defines terms to use within the architectu

34、re. This part of ISO 19125 does not attempt to standardize and does not depend upon any part of the mechanism by which Types are added and maintained, including the following: a) syntax and functionality provided for defining types; b) syntax and functionality provided for defining functions; c) phy

35、sical storage of type instances in the database; d) specific terminology used to refer to User Defined Types, for example UDT. This part of ISO 19125 does standardize names and geometric definitions for Types for Geometry. This part of ISO 19125 does not place any requirements on how to define the G

36、eometry Types in the internal schema nor does it place any requirements on when or how or who defines the Geometry Types. 2 Conformance In order to conform to this part of ISO 19125, an implementation shall satisfy the requirements of one or more test suites specified in the other parts of ISO 19125

39、004(E) 2 ISO 2004 All rights reservedNOTE Boundary is most commonly used in the context of geometry, where the set is a collection of points or a collection of objects that represent those points. In other arenas, the term is used metaphorically to describe the transition between an entity and the r

ISO 19107 4.2 buffer geometric object (4.14) that contains all direct positions (4.7) whose distance from a specified geometric object is less than or equal to a given distance ISO 19107 4.3 coordinate one of a sequence of n-numbers designating the position of a point

43、 a line 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. Connectiv

44、ity 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.

46、eature abstraction of real world phenomena NOTE A feature may occur as a type or an instance. Feature type or feature instance is used when only one is meant. adapted from ISO 19101 4.12 feature attribute characteristic of a feature (4.11) NOTE A feature attribute has a name, a data type, and a valu

47、e domain associated to it. A feature attribute for a feature instance also has an attribute value taken from the value domain. adapted from ISO 19101 4.13 geometric complex set of disjoint geometric primitives (4.15) where the boundary (4.1) of each geometric primitive can be represented as the unio

48、n of other geometric primitives of smaller dimension within the same set NOTE The geometric primitives in the set are disjoint in the sense that no direct position is interior to more than one geometric primitive. The set is closed under boundary operations, meaning that for each element in the geom

49、etric complex, there is a collection (also a geometric complex) of geometric primitives that represents the boundary of that element. Recall that the boundary of a point (the only 0D primitive object type in geometry) is empty. Thus, if the largest dimension geometric primitive is a solid (3D), the composition of the boundary operator in this definition terminates after at most 3 steps. It is also the case that the boundary of any object is a cycle. ISO 19107 4.14
