Thanks.  I see that, but I am not sure why, or what to do about it.  I do see that gdalinfo does display 0 for latitude, but also has other information.  Does this mean that the file is defective?  Or that there is a problem with gdalwarp?  
Is there some way, based on the information that gdalinfo is displaying that I can "correct" this?  

Thanks,
