The development of information products frequently requires the acquisition and combination of multiple datasets from different data suppliers. The manner in which the data is combined depends on the nature of the business need under consideration and may vary from the simple assembly of thematic representations through to sophisticated integration, analysis and rendering. In every case, the data suppliers and processors need to share a common understanding of the data’s characteristics to ensure their appropriate interpretation and use. The more complex or automated the processing becomes, the more necessary it is for this understanding to be unambiguous.
A challenge that arises when combining disparate datasets stems from differing terminology conventions adopted by the contributing suppliers.
The capacity to combine data that have been sourced from different professional communities is dependent upon a common comprehension of the terms and concepts used to describe the business leaning of the data. The availability of cross-mapping that reconciles the semantic differences between the communities vocabularies is therefore reguired.
BS EN ISO 19146:2018 establishes a methodology for cross-mapping between vocabularies, It is principally intended for use by geospatial communities but may have wider application.
BS EN ISO 19146:2018 applies the provisions of ISO 19135-1: 2015 to the registration of geospatial concepts. It also adopts terms and concepts that are taken from UML and terminology theory and practice.
BS EN ISO 19146:2018 establishes a methodology for cross-mapping vocabularies.It also an implementation of ISO 19135-1: 2015 for the purpose of registering cross-mapped vocabulary entries.
Methodologies for the development of ontologies and taxonomies that relate to geographic information and geomatics are not within the scope of this document.
