Geographic information. Registry of representations of geographic point location. | Status: Confirmed, Current

1 Scope This International Standard specifies the process for establishing, maintaining and publishing registers of representation of geographic point location in compliance with ISO 19135. It identifies and describes the information elements and the structure of a register of representations of geographic point location including the elements for the conversion of one representation to another. This International Standard also specifies the XML implementation of the required XML extension to ISO/TS 19135-2, for the implementation of a register of geographic point location representations. A registry of geographic point location representations differs from a coordinate reference system (CRS) registry as it is not intended to describe the parameters of a CRS including datum, projections, units of measure, and order of coordinates but is concerned by the manner a geographic point location according to ISO 6709 is physically represented in a record or part of it.
