If you can use HDF-EOS, you can check http://newsroom.gsfc.nasa.gov/sdptoolkit/userguide.html HDF-EOS Library User's Guide Volume 1: Overview and Examples<http://newsroom.gsfc.nasa.gov/sdptoolkit/docs/HDF-EOS_UG.pdf>for HDF-EOS2 HDF-EOS Interface Based on HDF5, Volume 1: Overview and Examples<http://newsroom.gsfc.nasa.gov/sdptoolkit/docs/HDF-EOS5_UG.pdf>for HDF-EOS5
HDF-EOS can assure the geographic projection is specified without providing lat/lon values. If you prefer to use HDF5 or netCDF-4, you definitely need to provide latitude and longitude values, An attribute called units="degrees_east" for longitude and units="degrees_north" for latitude should be specified to assure the CF compliant. check http://www.hdfgroup.org/HDF5/faq/cfattributes.html You may find HDF5, netCDF4 and HDF-EOS5 examples that may be similar to what you want to achieve. Some HDF5 examples can also be found under http://www.hdfgroup.org/ftp/HDF5/examples/ Kent On Sun, May 12, 2013 at 11:30 PM, Garrett Campbell < [email protected]> wrote: > I have data in a simple projection: cylindrical equidistant. > I would like to write something into the hdf file to specify the > projection. > Any idea what to specify? > Any examples? > Thanks > > -- > G.
