Investigation of Rapid Urbanization Processes Using ASTER, MODIS, and Landsat Data

Studies of human-dominated ecosystems (cities) are crucial for understanding the human impact on ecosystem and climatic processes. With half the global population now living in cities and the urban infrastructure of the world expected to double over the next 35 years, urban environments are playing an increasingly important role in daily quality-oflife issues, ecological processes, climate, flows of materials, and land transformations. The degree of this influence depends on biogeographic regions, urban structures, urban functions, and modes of growth. Models or scenarios of both historical urban development trajectories and future change in urban ecosystem structure and function must be developed with these variations in mind. The data from EOS sensors can provide multitemporal and multispatial information necessary for accurately parameterizing urban simulation models. With these retrospective and prospective tools, we plan to more effectively bring scientific research and technological innovations to bear in the service of global development and sustainability.

We propose to continue ongoing ASTER data collection and analysis efforts for 100 urban centers located around the globe. Land cover classifications will continue to be performed for the 100 current city targets, and we will focus intensive characterization and analysis efforts on a subset of 17 cities in concert with local investigators as collaborators. These intensive efforts for the subset of cities will include characterization of the geology, ecology, climate, urban form, and social aspects of each urban center. We will expand the ongoing Urban Environmental Monitoring project to use the multiple spatial, spectral, and temporal resolutions available from ASTER, MODIS, and Landsat MSS/TM/ETM+ data together with ancillary spatial and social information to perform these analyses.
