Quantifying impervious surface changes using time series planimetric data from 1940 to 2011 in four central Iowa cities, U.S.A.

Highlights: [•] Impervious surface area increased and became more connected over time. [•] Building and parking lot surfaces became more important in the last 20 years. [•] Spatial heterogeneity of surfaces was quantified in different percent IS zones. [•] Dominant impervious surfaces include roads (low IS zones), buildings (medium), and parking lots (high). [•] Policy and practice implementation to mitigate against IS impacts can be targeted in different percent IS zones. [ABSTRACT FROM AUTHOR]
