3 Non-geometry standards
Example 'ar a UML use-case diagram
The example has been taken from the ISO 19116 (Positioning services). It illustrates the use-cases for which the standard is primarily intended. The use-case diagram is informative and, therefore, is not normative.

3.1.2 Terminology (ISO 19104)
The ISO 19104 (Terminology) provides guidelines for collection and maintenance
of terminology in the field of geomatics. The main concept for setting up terminology demands that the same term is used for the same concept throughout the whole
family of standards. The ISO 19104 also lays down the guidelines for maintenance
ofthe terminology repository.
Each standard addresses its segment of geographic information and uses the most
appropriate terms found there. The ISO standard "Terminology" guarantees the consistency of all involved terms through the specification of a terminological record
and the description of principles for definition writing.
