When Portland designer Justin Palmer got his hands on a dataset of the city’s building construction dates, he did what any responsible Portland designer might do: make a color-coded, interactive map for local reference. A few days later, Brooklyn designer Thomas Rhiel published a similar map, based on figures in New York City’s recently released Property Land Use Tax lot Output (or PLUTO) report. In the weeks that followed, more maps surfaced as a series of international designers showed off their hometown pride — and indulged everyone’s fascination with data.
Palmer, for one, noticed that Portland’s ’50s-era housing boom relied on a grid system of development, whereas homes constructed in the ’80s and ’90s favored cul-de-sac formations. He wrote on his blog:
For other cities, the maps divulge reconstruction patterns. In Slovenia’s Ljubljana, for example, many buildings weren’t rebuilt for several years after a devastating 1895 earthquake, and then after both World Wars.
