Dear John
An experimental web service is available that examines NetCDF files and
tries to validate their use of Conventions such as CF-1.0 for gridded data.
We will be improving this in the future based on user experience and
feedback, and we will make it a part of the THREDDS Data Server.
Does this do the same kind of job as the CF checker (on the CF website) i.e.
verify the adherence to the CF conformance document (also on the CF website)?
Judging from the amount of feedback we get, the CF checker is pretty well used.
Hi Jonathan:
Thats a good question. The CF checker
(http://titania.badc.rl.ac.uk/cgi-bin/cf-checker.pl) is much improved since I
last looked, and I will add a link to it from my page.
The TDS tool is not a general-purpose CF-1.0 compliance checker, but more of a
practical tool that identifies the variables for which it can identify
georefrencing coordinate systems, using CF-1.0 or other Conventions that it
knows about (COARDS, etc). This accurately indicates what will be viewable in
applications like the IDV that use the Netcdf-Java library. It currently only
works on griddded data. My goal is to add better messages to indicate how to
fix any problems, but that's a long way off.
I would expect the two tools to be complementary, and I will be comparing the output with the CF checker to try to improve my tool.
Regards,
John
