DIN EN ISO 19109:2016-05

This document defines rules for creating application schemas. Any description of reality is always an abstraction, always partial, and always just one of many possible "views", depending on the application field. The widespread application of computers and geographic information systems has led to an increased use of geographic data within multiple disciplines. Geographic datasets are increasingly being shared and exchanged. To ensure that data is understood consistently and unambiguously by both computers and users, data structures for data access and exchange shall be fully documented using the methods in this standard. This standard differs from DIN EN ISO 19109:2006-09 as follows: a) clearer structure of the conformance classes in line with the corresponding recommendations of ISO/TC 211; b) consideration of metadata for the determination of properties of a feature according to DIN EN ISO 19156 "Geoinformation - Observations and measurements"; c) adaptation to ISO 19103:2015 and definition of a UML profile for DIN EN ISO 19109; d) adaptation of the General Feature Model to the use in practice; e) general revision for a clearer presentation of the requirements and recommendations. The committee responsible for this standard is NA 005-03-03 AA "Geoinformation (SpA zu CEN/TC 287+ISO/TC 211)" ("Geographic information (mirror committee to CEN/TC 287+ISO/TC 211)") at DIN.
