Th
14、e 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, governmental and non-gov
15、ernmental, 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 Directives, Part 2.
16、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 bodies casting a vo
17、te. 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 responsible for identifying any or all such patent rights. ISO 19116 was prepared by Technical Committee ISO/TC 211, Geographic information/Geomatics. Copyr

19、SO 19116:2004(E) ISO 2004 All rights reserved v Introduction 0.1 General Positioning services are among the processing services identified in ISO 19119. Processing services include services that are computationally oriented and operate upon the elements from the model domain, rather than being direc
20、tly integrated in the model domain itself. This International Standard defines and describes the positioning service. Other services in this domain are coordinate transformation, metric translation, format conversion, semantic translation, etc. Positioning services employ a wide variety of technolog
21、ies that provide position and related information to a similarly wide variety of applications, as depicted in Figure 1. Although these technologies differ in many respects, there are important items of information that are common among them and serve common needs of these application areas, such as
22、the position data, time of observation and its accuracy. Also, there are items of information that apply only to specific technologies and are sometimes required in order to make correct use of the positioning results, such as signal strength, geometry factors, and raw measurements. Therefore, this
23、International Standard includes both general data elements that are applicable to a wide variety of positioning services and technology specific elements that are relevant to particular technologies. Figure 1 Positioning services interface allows communication of position data for a wide variety of
24、positioning technologies and users Modern electronic positioning technology can measure the coordinates of a location on or near the Earth with great speed and accuracy, thereby allowing geographic information systems to be populated with any number of objects. However, the technologies for position
25、 determination have had neither a common structure for expression of position information, nor a common structure for expression of accuracy. The positioning- services interface specified in this International Standard provides data structures and operations that allow spatially oriented systems, su
26、ch as GIS, to employ these technologies with greater efficiency by permitting interoperability among various implementations and various technologies.

28、rate and use position information. Such systems may incorporate an instrument providing position updates to one or more position-using devices for data processing, storage, and display. For example, a navigation display system may include recording functions that store the history of a vehicles move
29、ment, processing tools that compute guidance updates along a planned course relying on stored waypoints, and a display device that provides the navigator with current position, computed guidance information, and cartography from stored coordinate information. This International Standard specifies an
30、 interface that carries position and related information among any of these components, and should be sufficient for communication between the position providing device and any connected position using devices. Additional interfaces may also exist in such a system, for example providing for cartogra
31、phic portrayal of stored coordinate information, which are outside the scope of this International Standard. Standard positioning services provide client systems with operations that access positioning results and related information in a uniform manner, isolating the client from the multiplicity of
32、 protocols that may be employed to communicate with the positioning instruments. For example, a realized-positioning service could communicate with a GNSS receiver using the well-known NMEA 0183 protocol, translate the information, and provide the positioning results to a geographic information disp
33、lay client through the ISO 19116 standard interface specified in this document. Another realized-positioning service could communicate with a GNSS receiver using a manufacturers proprietary binary protocol. Through the use of standardized positioning service interfaces, the hardware communication pr
34、otocols become transparent to the client application. Evolution of new communication protocols that closely follow the data structures described in this International Standard is also anticipated. Such communication standards will facilitate efficient fulfilment of the information requirements of th
35、e positioning services interface and facilitate modular interchangeability of the positioning technology components. 0.2 Potential use of the service The application of this International Standard is illustrated in Figure 2 by a simplified case for a user obtaining coordinates from a GNSS receiver.

38、her the system is operational. Next, the user sets the GNSS receiver to provide coordinates in the desired Coordinate Reference System (CRS) through the interface by performing setMode operations. For instance, the coordinate reference system could be set to NAD27 Virginia State Plane, North Zone, U
39、S Survey feet. Note that by using well-recognized CRS names in accordance with the ISO 19111 structure, the user avoids some of the complexity of the definition of the coordinate reference system by using a named datum and mapping projection, and the system interprets these and loads predefined set
40、of parameters. By performing technology-specific setOperatingConditions operations, the user also sets certain operating conditions of the system so that the position determination will be performed in a desired manner. For example, the user sets the satellite-elevation mask of the GNSS receiver so
41、that satellites that are at low angles in the sky, and consequently, more affected by signal passage through the atmosphere, are excluded from the computation. Certain other operating conditions, such as the current actual positions of available satellites, are not controllable by the user and are d
42、etermined by the system. The system then performs measurements according to the operating conditions of the signal from the GNSS satellites and uses these measurements to compute a position cast in the specified Coordinate Reference System. Finally, the computed position is reported to the user thro
43、ugh the PS_Observation data object. The positioning system also reports on certain operating conditions to help the user decide whether to use the position value. For example, one of the indicators of solution quality is the dilution of precision (DOP) value, which is based on the geometry of the sa
44、tellites observed to determine the position. Communication of this information is performed through the standard data structures to the users display device, which portrays it to the user.

47、dard specifies the data structure and content of an interface that permits communication between position-providing device(s) and position-using device(s) so that the position-using device(s) can obtain and unambiguously interpret position information and determine whether the results meet the requi
48、rements of the use. A standardized interface of geographic information with position allows the integration of positional information from a variety of positioning technologies into a variety of geographic information applications, such as surveying, navigation and intelligent transportation systems. This International Standard will benefit a wide range of applications for which positional information is important. 2 Conformance This International Standard defines
