AB: We have developed and tested a satellite-based regional land cover/use monitoring protocol. The approach is based on well-established algorithms used with coarse resolution satellite data and uses state-of-the-art processing techniques, including atmospheric corrections. Sub-pixel fractions of impervious cover and tree cover are derived at the 28.5m spatial resolution of the Landsat satellite data using air photography and used to detect and monitor urban growth and dynamics in the Upper Delaware River Watershed, which comprises a major water supply of urban centers such as New York City. A pilot project that examines urban growth patterns in Upper Delaware River Basin from 1984 to 2005 is presented as a demonstration of the protocols and includes field validation. These data are being used to simulate urban growth into the future and are an important tool for decision-making and urban planning in the entire watershed.
