title: Install Cartopy & dependencies on Windows
body: <p>I want to install Cartopy on Windows, which has some dependencies according to <a href="http://scitools.org.uk/cartopy/docs/latest/installing.html#installing" rel="noreferrer">http://scitools.org.uk/cartopy/docs/latest/installing.html#installing</a>. 
  When using <code>pip install cartopy</code> in the cmd prompt, it gives an error where it wants me to install GEOS 3.3.3 and Proj4 4.9.0.</p>
  
  <p>I've downloaded geos-3.6.2.tar.bz2, but I cannot figure out how to install it. I've extracted the files, used <code>cd</code> to the right directory. </p>
  
  <p>What can I do to install it correctly?
  Is there an easy way to install Cartopy?</p>
