246 Annexes
positioning system employing accelerometers, gyroscopes, and computer as integral
components to determine coordinates of points or objects relative to an initial known
reference point (lS048 2002)
information
knowledge conceming objects, such as facts, events, things, processes, or ideas, including concepts, that within a certain context has a particular meaning (lSOIEC07
1993, IS050 2002)
instance
object that realizes a class (lS039 2003)
individual entity with its own identity and value (lS049 2002)
NOTE
[Unified Modelling Language version 1.1]. A descriptOf specifies
the form and behaviour of a set of instances with similar properties.
instance model
representation model for storing data according to an application schema (lS050
2002)
instant
O-dimensional geometrie primitive representing position in time (lS040 2002)
integrated positioning system
positioning system incorporating two Of more positioning technologies (lS048 2002)
NOTE
The measurements produced by each positioning technology in an
integrated system may be any of position, motion, or attitude. There may be redundant measurements. When combined, a unified position, motion, or attitude is determined.
interval scale
scale with an arbitrary origin which can be used to describe both Ofdering of values
and distances between values (lS040 2002)
NOTE
Ratios ofvalues measured on an interval scale have no meaning.
interface
named set of operations that characterize the behaviour of an element (IS037 2000)
(lSOIEC47 2003, IS050 2002)
interior
set of a11 direct positions that are on a geometrie object but which are not on its
boundary (lS039 2003)
NOTE
The interiOf of a topological object is the homomorphic image of
the interiOf of any of its geometrie realizations. This is not included as adefinition
because it fo11ows from a theorem oftopology.
