|Areas of the Mutlnomah County, Oregon grouped into 5 clusters based on patterns of building age.
Each building is plotted individually using the colour assigned to its own cluster.
(data from City of Portland Open Data Initiative, background OSM)
My basic idea was to do something along the following lines:
- Partition the buildings into contiguous equal sized groups
- Create some kind of time-series for each group reflecting building history
- Run a clustering algorithm against the latter data
- See if it produced interesting results
