This issue doesn't have a moderator - I think that's why it's not progressed. I will moderate it. @snowman2's current proposal (https://github.com/cf-convention/cf-conventions/pull/282) is to replace
However, in those situations where two values of a given property are different, then the value specified by the single-property attribute shall take precedence. For example, if the semi-major axis length of the ellipsoid is defined by the grid mapping attribute semi_major_axis and also by the crs_wkt attribute (via the WKT SPHEROID[…] element) then the former, being the more specific attribute, takes precedence. with If both crs_wkt and grid mapping attributes exist, the attributes must be the same and grid mapping parameters should always be completed as fully as possible. As such, information from either one (or both) may be read in by the user without needing to check both. However, in those situations where the two values of a given property are different, the CRS information cannot be interpreted accurately and users should inform the provider so the issue can be addressed. For example, if the semi-major axis length of the ellipsoid is defined by the grid mapping attribute semi_major_axis and also by the crs_wkt attribute (via the WKT SPHEROID[…] element), the value of this attribute cannot be interpreted accurately. I think this is OK, except for the last sentence, which I think should be For example, if the semi-major axis length of the ellipsoid is defined by the grid mapping attribute semi_major_axis **disagrees with** the crs_wkt attribute (via the WKT SPHEROID[…] element), the value of this attribute cannot be interpreted accurately. That leads naturally to the unaltered final sentence, "Naturally if the two values are equal then no ambiguity arises." Philip @cameronsmith1 and Karl @taylor13, are you content with this? Alan @snowman2, is my amendment OK with you? Jonathan -- You are receiving this because you are subscribed to this thread.
