The International Standards Organization Technical Committee 211 (ISO/TC 211) on Geographic Information/Geomatics has taken responsibility for establishing the ISO Geodetic Registry, a registry of international geodetic reference systems and transformations. Such a registry is needed primarily by GIS software to define the various reference frames and transformations they use. The data contained in the registry are the parameters defining geodetic reference systems and adopted transformations between them and need to be validated by official sources. The ISO Geodetic Registry has been defined in accordance with the ISO International Standard (IS) 19127. This standard defines the data elements required, as well as the rules for its maintenance, in compliance with IS 19135 (procedures for registration of items) and IS 19111 (describing the elements necessary to fully define reference systems). As specified in IS 19135, the ISO Geodetic Registry consists of an online information system or database with a user interface and web services for access, a Registry Manager hosting the Registry and taking care of its daily operations, and a Control Body that approves the content of the Registry. The Norwegian Mapping Authority is serving as the initial Registry Manager and has funded and hosted the registry management software. The Control Body consists of geodetic experts nominated by the TC 211 member and liaison organizations with its chair and vice-chair nominated by the IAG. The ISO Geodetic Registry was made publically available earlier this year, populated with an initial set of global and regional reference frames and their associated transformations. Further population of the Registry continues and geodetic agencies are encouraged to submit their own reference frames and transformations. We describe the parameters required to be entered for such reference frames and transformations and provide the status of revisions of the supporting standards IS 19111 and IS 19127.
