The Open Geospatial Consortium (OGC) seeks public comment on the candidate standard jointly developed by the International Organization for Standardization (ISO) and the Open Geospatial Consortium: “Geographic Information - Well-Known Text representation of coordinate reference systems” (CRS WKT). Well-Known Text (WKT) is used as a compact machine- and human-readable representation of geometric objects and coordinate reference information, as specified two decades ago in the OGC and ISO standard. The original CRS WKT was subsequently extended in numerous incompatible ways, and had thus become non-interoperable. In 2015, OGC and ISO adopted a major revision of the CRS WKT specification that allowed a rigorous description of coordinate reference systems and coordinate operations in WKT. This latest edition of CRS WKT cancels and replaces the 2015 version, which has been technically revised. The candidate CRS WKT standard was prepared by the OGC CRS Standards Working Group and Technical Committee ISO/TC 211 Geographic information/Geomatics.
