20、9111:2007iv Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject f

21、or 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, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on

22、 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 committees is to prepare International Standards. Draft International Standards adopted by the technical committees a

23、re 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 possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held

24、responsible for identifying any or all such patent rights. ISO 19111 was prepared by Technical Committee ISO/TC 211, Geographic information/Geomatics, in close collaboration with the Open Geospatial Consortium (OGC). This second edition cancels and replaces the first edition (ISO 19111:2003), which

25、has been technically revised. EN ISO 19111:2007vIntroduction Geographic information contains spatial references which relate the features represented in the data to positions in the real world. Spatial references fall into two categories: those using coordinates; those based on geographic identifier

26、s. Spatial referencing by geographic identifiers is defined in ISO 19112 4. This International Standard describes the data elements, relationships and associated metadata required for spatial referencing by coordinates. It describes the elements that are necessary to fully define various types of co

27、ordinate systems and coordinate reference systems applicable to geographic information. The subset of elements required is partially dependent upon the type of coordinates. This International Standard also includes optional fields to allow for the inclusion of non-essential coordinate reference syst

28、em information. The elements are intended to be both machine and human readable. The traditional separation of horizontal and vertical position has resulted in coordinate reference systems that are horizontal (2D) and vertical (1D) in nature, as opposed to truly three-dimensional. It is established

29、practice to define a three-dimensional position by combining the horizontal coordinates of a point with a height or depth from a different coordinate reference system. In this International Standard, this concept is defined as a compound coordinate reference system. The concept of coordinates can be

30、 expanded from a strictly spatial context to include time. ISO 19108 describes temporal schema. Time can be added as a temporal coordinate reference system within a compound coordinate reference system. It is even possible to add two time-coordinates, provided the two coordinates describe different

31、independent quantities. EXAMPLE An example is the time/space position of a subsurface point of which the vertical coordinate is expressed as the two-way travel time of a sound signal in milliseconds, as is common in seismic imaging. A second time-coordinate indicates the time of observation, usually

32、 expressed in whole years. Certain scientific communities use three-dimensional systems where horizontal position is combined with a non-spatial parameter. In these communities, the parameter is considered to be a third, vertical axis. The parameter, although varying monotonically with elevation or

33、depth, does not necessarily vary in a simple manner; thus, conversion from the parameter to height or depth is non-trivial. The parameters concerned are normally absolute measurements and the datum is taken with reference to a direct physical measurement of the parameter. These non-spatial parameter

34、s are beyond the scope of this International Standard. However, the modelling constructs described within this International Standard can be applied through a profile specific to a community. In addition to describing a coordinate reference system, this International Standard provides for the descri

35、ption of a coordinate transformation or a coordinate conversion between two different coordinate reference systems. With such information, spatial data referred to different coordinate reference systems can be related to one specified coordinate reference system. This facilitates spatial data integr

36、ation. Alternatively, an audit trail of coordinate reference system manipulations can be maintained. EN ISO 19111:2007blank1Geographic information Spatial referencing by coordinates 1 Scope This International Standard defines the conceptual schema for the description of spatial referencing by coordi

37、nates, optionally extended to spatio-temporal referencing. It describes the minimum data required to define one-, two- and three-dimensional spatial coordinate reference systems with an extension to merged spatial-temporal reference systems. It allows additional descriptive information to be provide

38、d. It also describes the information required to change coordinates from one coordinate reference system to another. In this International Standard, a coordinate reference system does not change with time. For coordinate reference systems defined on moving platforms such as cars, ships, aircraft and

39、 spacecraft, the transformation to an Earth-fixed coordinate reference system can include a time element. This International Standard is applicable to producers and users of geographic information. Although it is applicable to digital geographic data, its principles can be extended to many other for

40、ms of geographic data such as maps, charts and text documents. The schema described can be applied to the combination of horizontal position with a third non-spatial parameter which varies monotonically with height or depth. This extension to non-spatial data is beyond the scope of this Internationa

41、l Standard but can be implemented through profiles. 2 Conformance requirements This International Standard defines two classes of conformance, Class A for conformance of coordinate reference systems and Class B for coordinate operations between two coordinate reference systems. Any coordinate refere

42、nce system claiming conformance to this International Standard shall satisfy the requirements given in A.1. Any coordinate operation claiming conformance to this International Standard shall satisfy the requirements given in A.2. 3 Normative references The following referenced documents are indispen

43、sable for the application of this document. For dated references, only the cited edition applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

44、n Temporal schema ISO 19115, Geographic information Metadata Normative reference to ISO 19115 is restricted as follows. In this International Standard, normative reference to ISO 19115 excludes the MD_CRS class and its component classes. ISO 19115 class MD_CRS and its component classes specify descr

45、iptions of coordinate reference systems elements. These elements are modelled in this International Standard. NOTE The MD_CRS class and its component classes were deleted from ISO 19115:2003 through Technical Corrigendum 1:2006. EN ISO 19111:20072 4 Terms and definitions For the purposes of this doc

46、ument, the following terms and definitions apply. 4.1 affine coordinate system coordinate system in Euclidean space with straight axes that are not necessarily mutually perpendicular 4.2 Cartesian coordinate system coordinate system which gives the position of points relative to n mutually perpendic

47、ular axes NOTE n is 2 or 3 for the purposes of this International Standard. 4.3 compound coordinate reference system coordinate reference system using at least two independent coordinate reference systems NOTE Coordinate reference systems are independent of each other if coordinate values in one can

48、not be converted or transformed into coordinate values in the other. 4.4 concatenated operation coordinate operation consisting of sequential application of multiple coordinate operations 4.5 coordinate one of a sequence of n numbers designating the position of a point in n-dimensional space NOTE In

49、 a coordinate reference system, the coordinate numbers are qualified by units. 4.6 coordinate conversion coordinate operation in which both coordinate reference systems are based on the same datum EXAMPLE Conversion from an ellipsoidal coordinate reference system based on the WGS 84 datum to a Cartesian coordinate reference system also based on the WGS 84 datum, or change of units such as from radians to degrees or feet to meters. NOTE A coordinate conversion uses parameters which have specified values that are not determined empirically. 4.7 coo
