Exploring the potential of OSM Data in the Identification of Buildings Illegally Developed on the Riparian Zone of Ngong River-Kenya

Abstract

Background

One of the main cause of urban floods in Kenya, which has been identified by many researchers is illegal settlement and development of structures along the riparian zones of rivers that pass through or near urban centers. Such structures usually interfere with the smooth flow of water and hence increasing the chances of flooding. In this research, we sought to find out if OSM data can help in identifying the illegal structures which were interfering with the smooth flow of water in Ngong River in Nairobi-Kenya
