title: Image modelling/stiching
body: <p>I was going through the <a href="http://www.nytimes.com/interactive/2015/04/25/world/asia/nepal-landmarks-before-after-earthquake.html?_r=0" rel="nofollow">link</a> where NYTimes compared the Nepal before earthquake and after earthquake. Can anyone tell apart from photostiching/panorama and internet browser technology, What different different technologies have been used in creating this?</p>
  
  <p>How can I learn about creating such stuff?</p>
