Landsat’s Critical Role in Urban Planning
Cities are places of light, action, complex social interactions, multi-faceted cultures, and fast-paced living. It’s no wonder cities are growing faster than rural areas. Earth experienced a milestone in the history of urban landscapes in 2008-09. More than 50 percent of the world’s human population now lives in areas of contiguous urban development. People are driving landscape-scale changes on our planet. Considering that people change the land surface, vegetation, water cycle, radiant heat, and other aspects of the landscape, the nature of this milestone has important implications for life. Using Landsat data, people can monitor urban change and also forecast patterns of change in future urban landscapes. Landsat sensors employ a spatial resolution of 30 m, an ideal scale for observing human impacts on the land. The sensors detect urban growth with visible and infrared reflectivity consistently, objectively, and dependably over time.
