ISO Geodetic Registry (ISOGR)
The ISO Geodetic Registry is a structured database of coordinate reference systems (CRS) and transformations that is accessible through this online registry system. The Register includes only systems and transformations of international application. It does not include all possible coordinate reference systems and transformations.
This Registry is provided under the auspices of ISO Technical Committee 211 on geographic information/geomatics and conforms to the following ISO standards:
- ISO 19111:2007 (Spatial referencing by coordinates)
- ISO 19127:2019 (Geodetic register)
- ISO 19135-1:2015 (Procedures for item registration -- Part 1: Fundamentals)
Work is also underway to upgrade the Registry to conform to the recently revised ISO 19111:2019 standard, which includes support for dynamic datums and geoid-based datums.
July 2022: ISO/TC 211, OGC and IOGP have jointly published the "Guide to Coordinate Reference System (CRS) Resources". The guide describes basic information and the intended purposes of the three authoritative CRS registers: EPSG, ISO Geodetic and OGC CRS registries, for the user community.
