Right Here Right Now application is an application showing real time data regarding the city of Chicago. It is reachable from here.

At the beginning, the application shows, in the central part of the screen, an interactive map of the city of Chicago. The left part of the screen, is reserved to the menu, here there is the possibility to choose how two select a path, and the kind of information you want to show or hide on the map.


The right part of the screen is reserved for graphs. The graphs will show up upon request and will give the user some comparison between the selected area and the whole city of Chicago.


Upon user request, some menu will show up over the map. Those menus will provide information about the weather and twitter.
On the left side of the screen there are also some basic controls for the map.


In the lower part of the screen you can switch from a normal view of the map, to an aerial view and, thanks to the plus and minus button , you can zoom in and zoom out from the map.


There is nothing more easy that selecting a path. To do so, you have only to select the type of path you want to consider. You can choose on :
  • Path
  • Bounding Box
  • Rectangle
  • Clear


Path is the simplest type. Clicking on this, you can draw a path from a point to another point by simpling clicking twice on the map. Once you click on the path button, it will highlight, so that you can understand which kind of you are using. Now, click on the first point, and then on a second point. A line highlighting the path will show up, calculating for you the shortest point between those two points.


Bounding Box.By clicking on this button, you will have a rectangle plus a path,drawn and the data that will be fetcted regards that rectangle.


Rectangle can be used insted of the Path. The rectangle, instead of drawing all the path, will focus on an area. Once you select two points a rectangular area will highlight and data regarding that area will be fetched.
Clear option is obviously not a way to draw a path. By clicking on this button, the map will clear all the thing that are drawn giving you the possibility of start a new path.
N.B there is always the possibility to choose the radius of the selection. To do so, you can use the scroll bar on the right part of the menu. By increasing the value, more data will be fetched as we are considering a bigger area.
