ANSI INCITS ISO-19116-2004 pdf download Geographic information — Positioning services
1 Scope
This International Standard 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 requirements 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 two levels of conformance: Basic (that all implementations shall meet) and Extended (for technology-specific data related to a positioning system). Any positioning services implementation or product claiming conformance with this part of the International Standard shall pass all the requirements described in the corresponding abstract test suite set forth in Annex A.

4 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
4.1
accuracy
closeness of agreement between a test result and the accepted reference value [ISO 3534-1]
NOTE For positioning services, the test result is a measured value or set of values.
4.2
attitude
orientation of a body, described by the angles between the axes of that body’s coordinate system (4.5) and the axes of an external coordinate system (4.5)
NOTE In positioning services, this is usually the orientation of the user’s platform, such as an aircraft, boat, or automobile.
4.3
coordinate
one of a sequence of n numbers designating the position of a point in n-dimensional space
[ISO 19111]
NOTE In a coordinate reference system, the numbers must be qualified by units.
4.4
coordinate reference system
coordinate system (4.5) that is related to the real world by a datum (4.6)
[ISO 19111]
NOTE For geodetic and vertical datums, it will be related to the Earth.
4.5
coordinate system
set of mathematical rules for specifying how coordinates (4.3) are to be assigned to points
