NOTE
A eomposite eurve, as a set of direet positions, has all the properties of a eurve.
composite solid
eonneeted set of so lids adjoining one another along shared boundary surfaees (IS039
2003)
NOTE
A eomposite solid, as a set of direet positions, has all the properties
ofa solid.
composite surface
eonneeted set of surfaees adjoining one another along shared boundary eurves
(lS0392003)
NOTE
A eomposite surfaee, as a set of direet positions, has all the properties of a surfaee.
compound Coordinate Reference System
deseription of position through two independent Coordinate Referenee Systems to
deseribe a position (IS043 2003)
EXAMPLE
One Coordinate Referenee System based on a two- or threedimensional eoordinate system and the other Coordinate Referenee System based on
a gravity-related height system.
computational geometry
manipulation of and ealeulations with geometrie representations for the implementation of geometrie operations (IS039 2003)
EXAMPLE
Computational geometry operations include testing for geometrie
inclusion or interseetion, the ealeulation of eonvex hulls or buffer zones, or the finding of shortest distanees between geometrie objeets.
computational topology
topologieal eoneepts, struetures and algebra that aid, enhanee or define operations on
topologieal objeets usually performed in eomputational geometry (lS039 2003)
concept
unit of knowledge ereated by a unique eombination of eharaeteristies (lSOlO 2000,
IS0362002)
NOTE
Coneepts are not neeessarily bound to partieular languages. They
are, however, influeneed by the social or eultural baekground whieh often leads to
different categorizations.
concept system
set of eoncepts struetured aecording to the relations among them (ISO I 0 2000,
IS0362002)
concept harmonization
