N2 - The spatial expansion of Accra’s residential areas has been remarkable during the last decade. Following the implementation of liberalization policies from 1983 to the present, many legal obstacles to investments in the housing sector have gradually been removed. The peri-urban development is dominated by residential areas of low density with one- or two-story houses. Most areas are in need of services and infrastructure. Visually these new urban areas are characterized by a high percentage of plots covered with natural vegetation or exposed surfaces in between finished or partly finished buildings. This chapter discusses methods for satellite-based classification of peri-urban neighborhoods in order to support a more efficient planning process for service and infrastructure provision. More specifically, the chapter focuses on methods for mapping the continuum of urban development levels found within the fringe areas of Accra. The goal is to produce maps that depict the spatial properties of this gradual rural-to-urban transition zone more accurately than those produced using traditional image classification strategies.
