Annex A: Terms and definitions ofthe ISO 19100 standards
253
totality of characteristics of a product that bear on its ability to satisfY stated and implied needs (IS034 2002)
quality schema
conceptual schema defining aspects of quality for geographie data (IS034 2002)
re cord
finite, named collection ofrelated items (objects or values) (IS039 2003)
NOTE
Logically, arecord is a set ofpairs.
reference data
data accepted as representing the universe of discourse, to be used as reference for
direct external quality evaluation methods (IS046 200 I)
relative position
position of a point with respect to the positions of other points (IS048 2002)
NOTE
The spatial relationship of one point relative to another may be
single-, two- or three-dimensional.
relative positional accuracy
closeness of coordinate difference value to the true or accepted value in a specified
reference system (IS048 2002)
NOTE
Closely related terms such as local accuracy are employed in various countries, agencies, and application groups. Where such terms are utilized, a description of the term should be provided.
resource
asset or means that fulfils a requirement
EXAMPLE
Dataset, service, document, person or organization (IS047 2003)
ring
simple curve which is a cycle
NOTE
Rings are used to describe boundary components of surfaces in 2D
and 3D coordinate systems. (IS039 2003)
satellite positioning system
positioning system based upon receipt of signals broadcast from satellites (IS048
2002)
NOTE
In this context, satellite positioning implies the use of radio signals
transmitted from "active" artificial objects orbiting the Earth and received by "passive" instruments on or near the Earth's surface to determine position, velocity,
and/or attitude of an object. Examples are GPS and GLONASS.
