The DEVELOP team at Marshall Space Flight Center worked to help improve methods for controlling aquatic vegetation in North Alabama. Using Landsat 7 ETM+ and vegetation indices, the team created a method to map aquatic vegetation and points of agricultural source pollution.

Classified Landsat 7 scene in Ghana (193/55) showing forested and disturbed areas between 2002 and 2007 based on automated disturbance algorithm. Image Credit: DEVELOPBased on field surveys, agricultural fires have historically been the primary cause of deforestation in Ghana. Does slash-and-burn agriculture still influence deforestation in Ghana today? Using satellite imagery, Goddard Space Flight Center (GSFC) DEVELOP interns created automated recent deforestation products combined with fire detections to reveal the impact of agricultural burning on Ghana’s forests.

One uses traditional coal-burning technology, and the other uses innovative ‰ÛÏclean coal‰Û-fired technology. With two plants within miles of one another, this project aims to use NASA Earth observations to monitor and compare the environmental impacts of each.
