     1This page was created to list/track progress as a supplement to work in October 2011 on wiki:NetCDF_Improvements, specifically wiki:NetCDF_exportUpdateChanges.

     3The list of supported CF-1.5 projections is shown at http://cf-pcmdi.llnl.gov/documents/cf-conventions/1.5/apf.html .
     4
     5Hopefully 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.

     7||'''Projection'''||'''Export- CF compliance'''||'''Export - openable by NetCDF Java'''||Updated||Note||
     8||AEA||Yes||Yes||18/10/11||Tested 2 Std Parallels export only||
     9||AzEq||Yes||No||18/10/11||See (1) below||
     10||LAzEqA||Yes||Yes||18/10/11||||
     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.||
     12||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||
     13||M-1SP||Yes||No||18/10/11||See (1) below||
     14||M-2SP||Yes||Yes*||18/10/11||Loads in NetCDF Java and IDV, but appears translated from expected position||
     15||Ortho||Yes||Yes||18/10/11||||
     16||Polar St||Yes*||?||18/10/11||See (2) below||

     21General notes:
     22
     23(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]]
     24(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.
     25(3) Rotated pole: Not able yet to test: as seems GDAL needs support of advanced proj4 strings that can handle rotated coord systems.
