  1. URBAN COASTAL HABITAT MAPPING USING LANDSAT AND QUICKBIRD IMAGERIES By: Linda Kpormone Buame Department of Oceanography and Fisheries Date: 18th January,2011

  2. Outline • Background • Objectives and Justification • Approach • Preliminary results Urban Coastal Habitat Mapping using Landsat and Quickbird Imageries

  3. Background • “Coastal habitats are the biosphere’s most imperiled ecosystems.” • Coastal habitats present in Ghana are; wetlands, deltas, mangroves, lagoons, estuaries, sea grass, etc. • This project seeks to provide baseline information (in a digitized format), of critical coastal habitats in the Greater Accra Region. Urban Coastal Habitat Mapping using Landsat and Quickbird Imageries

  4. Objectives and Justification • To classify habitats including ecosystems and investigate the impacts of urbanization on coastal habitats. • To compare and contrast the quality of features shown in Quickbird and Landsat Imageries to identify the most appropriate for coastal habitat mapping. • To understand how Quickbird and Landsat imageries can be applied to the mapping of coastal habitats in urban areas.
