This page was created to list/track progress as a supplement to work in October 2011 on wiki:NetCDF_Improvements, specifically wiki:NetCDF_exportUpdateChanges.

The list of supported CF-1.5 projections is shown at ​http://cf-pcmdi.llnl.gov/documents/cf-conventions/1.5/apf.html .

Hopefully the shorthand projection names listed below are fairly self-explanatory - they've been listed in the same order as that shown on the CF-1.5 appendix page.

Projection	Export- CF compliance	Export - openable by NetCDF Java	Updated	Note
AEA	Yes	Yes	18/10/11	Tested 2 Std Parallels export only
AzEq	Yes	No	18/10/11	See (1) below
LAzEqA	Yes	Yes	18/10/11
LC-2SP	Yes	Yes	18/10/11	The OGC WKT Lambert_Conformal_Conic_2SP maps clearly to LC in CF-1 with 2 std parallels. Am not sure if OGC WKT Lambert_Conformal_Conic_1SP can be converted directly to LC in CF-1 using just 1 std parallel.
LCEA	Yes	No	18/10/11	Works for 1 std parallel version. CF-1 claims can use a scale_factor instead of std parallel, not sure WKT equiv
M-1SP	Yes	No	18/10/11	See (1) below
M-2SP	Yes	Yes*	18/10/11	Loads in NetCDF Java and IDV, but appears translated from expected position
Ortho	Yes	Yes	18/10/11
Polar St	Yes*	?	18/10/11	See (2) below
Rot Pole	N	N	18/10/11	See (3) below
St	Yes	Yes	18/10/11
TM	Yes	Yes	18/10/11

General notes:

(1) For projections that won't load correctly as referenced grids in NetCDF Java, we've contacted the developers to ask for clarification/testing support. In most cases, the CF-1 attributes seem appropriate.
(2) Polar stereographic: This projection's parameters in CF-1 are quite unusual, and significantly different from ​http://www.remotesensing.org/geotiff/proj_list/polar_stereographic.html. In particular finding a CF-1 equivalent for 'latitude of natural origin' is proving difficult. (3) Rotated pole: Not able yet to test: as seems GDAL needs support of advanced proj4 strings that can handle rotated coord systems.
