There is plenty of visible information including traffic patterns, heating systems functioning, and even the sunrise and sunset and the look of the environment give you an idea that it is a cold winter day. Underneath this, buried in the permafrost, are water and sewer pipes that move water and sewage produced by the community. Invisible flow data helps engineers and planners determine system capacity and future development needs. Another invisible metric is the flow of goods. Being a city located on an island, goods are flown in during the winter from southern Canada. Perhaps we may see these goods come off the plane but once distributed, their flow from shops to consumers is often times hidden. Therefore, retail buying patterns can also help planners design communities if they can understand where people shop, how they shop, and at what times. ![enter image description here][1] [1]: http://i1218.photobucket.com/albums/dd404/arifsayani/NIK_5494EXPORT.jpg
