Features:

• The process of using the application is done in just three easy steps. In fact, the third step is where the user can browse the results.
  
• Initially, a 2D map of Toronto is viewable with street names.
  
• A translucent compass is displayed on the lower left, conveying the camera's orientation relative to the North Pole.
  
• If explicit control is required, the map can be navigated using traditional 3D camera operations (pan, orbit, zoom).
  
• The user can enter the addresses of any place that he is interested in within Toronto. These locations appear as green houses on the map.
  
• There are a variety of services for the user to select, and the user can give different importance weights for each.
  
• As a user selects a service as being important, 3D buildings immediately populate the 2D map, showing the user all service locations in Toronto at once.
  
• Each service has representative 3D geometry. Colours, icons, and geometry are diverse so that individual service types are easily discernable.
  
• Mouse over any building for the name of the institution and the address, as specified by GIS data.
  
• A semi-transparent legend dynamically changes to show the relationship between each selected service, and its representative geometry.
  
• The results are displayed in ascending order, ranked quantitatively (lower values are better) based on the sum of distances to each service, multiplied by the importance weight set for each service. The residence with the smallest value, which is the best, is highlighted on the map with a rotating gold star.
  
• Arcs connect each of the residences to all of the closest services. The height of each arc indicates the relative importance weighting supplied by the user.
  
• Each row of the results table has a GO button, that when clicked causes the camera to make a transition to frame that residence and its closest services. The user can now easily left-drag to orbit that property for further inspection.
  
• At any time, the user may go back to previous steps to modify any input parameters.
