R/SirI have an issue related to CF conventions 2D coordinate variables (I mean lat/lon arrays corresponding to satellite images) I have been able to handle the case where lat/lon arrays have one to one correspondence with satellite imagery pixels.But if we have some scaling like: 1. Image Data ( 5600* 5600) Lat/Lon Arrays (1400*1400) each Or I have the other ways 2. Image Data(1400x1400) Lat/Lon Arrays (2800*2800).How to indicate that in the image pixel should refer to which Lat/Lon array pixel. Like in first case every four pixels of image correspond to 1 lat/lon array pixel.I am using HDF 4 for writing products.I have tried to search on internet. It says something about dimscale. But I am not aware what exactly to do.regards Ghansham _______________________________________________ cf-satellite mailing list cf-satellite@xxxxxxxxxxxxxxxx For list information or to unsubscribe, visit: http://www.unidata.ucar.edu/mailing_lists/
HI Ghansham:1. I understand that HDF-EOS has a convention for your situation. Are you using that? Could you explain how it works?
2. CF uses netCDF as its file format. HDF4 lacks shared dimensions, so is not an complete fit to the CF model. Why are you writing in HDF4?
