title: GeoTIFF to HDF Conversion?
body: <p>I'm in a big trouble. I've downloaded a GeoTIFFF Dataset from <a href="http://earthexplorer.usgs.gov/" rel="nofollow">http://earthexplorer.usgs.gov/</a> ; my problem is that I need the dataset in HDFv4 format, because I've to open it in IDL (please don't tell me "IDL can open GeoTIFF", I NEED HDFv4 format) . May you please suggest me a tool that does this conversion?</p>
  
  <p>Thanks a lot.</p>
