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.[[BR]]
(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.
