Hi,
I'm working on understanding how to properly express nominal and precise locations for timeSeriesProfile data from an oceanographic mooring. Here is the text from section 9.5 at
http://cf-pcmdi.llnl.gov/documents/cf-conventions/1.6/cf-conventions.html#coordinates-metadata:
CF Discrete Geometries provides a mechanism to encode both the nominal and the precise positions, while retaining the semantics of the idealized feature type. Only the set of coordinates which are regarded as the nominal (default or preferred) positions should be indicated by the attribute axis, which should be assigned string values to indicate the orientations of the axes (X, Y, Z, or T). See example A9.2.3.2. Auxiliary coordinate variables containing the nominal and the precise positions should be listed in the relevant coordinates attributes of data variables. In orthogonal representations the nominal positions could be coordinate variables, which do not need to be listed in the coordinates attribute, rather than auxiliary coordinate variables.
I can't find example "A9.2.3.2", but did find example H.5 which looks to be the correct one. Is this just a simple typo in the above text?
-Mike
