![enter image description here][1] **Visible information**: I've chosen this picture because it shows the historical part of Boston combined with the contemporary one. Also, some types of transportation can be observed such as: automobiles, buses and bicycles. Another significant point which I've considered about this picture is the open- market place located in an important square in downtown.That turns downtown more livable,enjoyable,and pleasurable where people can stop for eating, chatting and even seeing some art presentations ( open-gallery, street performance, music concerts, and so on.) **Invisible information:** I believe the two important invisible information present in this picture are the data collect from the Hubways (bike sharing system) and the solar panels that might be presented in that contemporary big tower. Firstly, all the date collect from the Hubway can be used to identify/answer several topics that help to understand cities. For instance: How many people are using bikes as a transportation during the week and weekend? How many people are using them as leisure? What is the demand for that type of transportation? How solar energy has been efficient to maintain the equipment? How is the Hubway linked with other transportation types? What is user's directions when utilizing bikes? Are people taking alternative routes that have not been optimized for biking? What can be improved with this system? and so on... Secondly, as it can be seen in the picture that biggest tower apparently is able to collect a wide range of solar energy. How do that exterior glass wall that involves the building works? is it sustainable for the building? Is it able to turns the solar energy into electricity for the building's usage? How efficient is it? How much can be saved on the electricity bill by doing so? [1]: https://edxuploads.s3.amazonaws.com/14137412514441883.jpg
