36、er bodies). 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, government

37、al and 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 Direct

38、ives, 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 bodie

40、omatics. ISO 19107:2003(E) ISO 2003 All rights reserved ixIntroduction This International Standard provides conceptual schemas for describing and manipulating the spatial characteristics of geographic features. Standardization in this area will be the cornerstone for other geographic information sta

41、ndards. A feature is an abstraction of a real world phenomenon; it is a geographic feature if it is associated with a location relative to the Earth. Vector data consists of geometric and topological primitives used, separately or in combination, to construct objects that express the spatial charact

42、eristics of geographic features. Raster data is based on the division of the extent covered into small units according to a tessellation of the space and the assignment to each unit of an attribute value. This International Standard deals only with vector data. In the model defined in this Internati

43、onal Standard, spatial characteristics are described by one or more spatial attributes whose value is given by a geometric object (GM_Object) or a topological object (TP_Object). Geometry provides the means for the quantitative description, by means of coordinates and mathematical functions, of the

44、spatial characteristics of features, including dimension, position, size, shape, and orientation. The mathematical functions used for describing the geometry of an object depend on the type of coordinate reference system used to define the spatial position. Geometry is the only aspect of geographic

45、information that changes when the information is transformed from one geodetic reference system or coordinate system to another. Topology deals with the characteristics of geometric figures that remain invariant if the space is deformed elastically and continuously for example, when geographic data

46、is transformed from one coordinate system to another. Within the context of geographic information, topology is commonly used to describe the connectivity of an n-dimensional graph, a property that is invariant under continuous transformation of the graph. Computational topology provides information

47、 about the connectivity of geometric primitives that can be derived from the underlying geometry. Spatial operators are functions and procedures that use, query, create, modify, or delete spatial objects. This International Standard defines the taxonomy of these operators in order to create a standa

48、rd for their definition and implementation. The goals are to: a) Define spatial operators unambiguously, so that diverse implementations can be assured to yield comparable results within known limitations of accuracy and resolution. b) Use these definitions to define a set of standard operations tha

49、t will form the basis of compliant systems, and, thus act as a test-bed for implementers and a benchmark set for validation of compliance. c) Define an operator algebra that will allow combinations of the base operators to be used predictably in the query and manipulation of geographic data. Standardized conceptual schemas for spatial characteristics will increase the ability to share geographic information amo
