I knew there had to be a different way to do it, I didn't like the three lists in there either :-) One thing: I had to change the line wRes = float(data[1][1:]) it was returning '00,' (zero, zero, comma) instead of '400', so I changed it to this: wRes = float(data[1][:3]) but then I thought, what if I get a tif with a resolution that is <> than 3 digits? So I opted for this wRes = float(data[1].strip(',')) which seems to work fine. Thanks again!!
