Here is the base map of 5 years of housing data in Ottawa-Carleton.  Each dot represents a "completion" (a single or semi-detached house whose construction was completed in the given year).  The colours represent the year of completion.  Click this map to begin the process of stepping-through from 1994 to 1998 (clicking each subsequent map steps you through each year).  Clicking the last map will bring you back to the Case-Studies page.
