Can we do something cool with the now openly available property assessment data that many cities are releasing? Is there a way we can show both overall city trends and detailed parcel-level comparisons while still having interactions feel instantaneous? Can all that be shown without overwhelming users?
We dug into a number of different technologies to find a way to make the visuals respond quickly while giving the user the ability to interact at the level of an individual home. This detailed representation reveals patterns that are obfuscated with higher level summaries. Seeing these patterns can help you better understand geographic trends in your city.
The result is a tool that lets users see the relative pricing of homes very quickly. Simply click on a property to have all other properties coloured relative to your selection. Or click through the guided tour of the city to discover some of the stories we found. We have maps for maps for Edmonton, Vancouver, and San Francisco.
