Hi,

Im just starting to use geotiffs as well. I have been having a hard time 
figuring out how to really even start. I have all the lat/longs and have already 
converted them into UTM. Im not sure what you are supposed to do for steps 2 to 
4 mentioned earlier. If you could explain or post snippets of code with 
explanation that would be great.
