Dr. Jeff de La Beaujardiere receives OGC Lifetime Achievement Award
Jeff’s support of open standards and OGC’s FAIR mission has improved access to Earth science information for countless users and decision-makers globally.
Well-known text representation of coordinate reference systems
Overview
This Standard provides an updated version of WKT representation of coordinate reference systems that follows the provisions of ISO 19111:2007 and ISO 19111-2:2009. It extends the earlier WKT to allow for the description of coordinate operations. This International Standard defines the structure and content of well-known text strings. It does not prescribe how implementations should read or write these strings. The jointly developed draft has also been submitted by ISO TC211 for publication as an International Standard document. The version incorporates comments made during both the OGC Public Comment Period as well as the ISO ballot for DIS (ISO TC211 document N3750).
