2.  Background  Objectives and Justification  Approach  Preliminary results 10/19/2015 Urban Coastal Habitat Mapping using Landsat and Quickbird Imageries 2

3.  “ 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. 10/19/2015 Urban Coastal Habitat Mapping using Landsat and Quickbird Imageries 3

4.  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. 10/19/2015 Urban Coastal Habitat Mapping using Landsat and Quickbird Imageries 4

5.  Study Area: Selected coastal areas in Greater Accra Region. 10/19/2015 Urban Coastal Habitat Mapping using Landsat and Quickbird Imageries 5 b) Landsat imagery 1.Acquisition of Quickbird and Landsat Imageries 2. Image Classification Supervised Unsupervised Decision Tree using ENVI 4.3 3. Image enhancement 4. Interpretation of data 5. Time series analysis using Landsat Imageries 6.Identification of Hot spot areas using Quickbird Imageries 7.Field Survey, collection of data and Ground truthing* 8. Perform geometric correction using GCPs and repeat steps 2-4 9. GIS archiving Distribution of results Flowchart showing approach of the project a) Quickbird imagery
