Contemporary cities, particularly in developing countries, experience an accelerating rate of changes and expansion. Such development has instigated the need for use of a fast technique that could adequately update the map of urban areas. This book demonstrates the application of Remote Sensing and Geographic Information System (GIS) in revising township map. It elucidates how a conventional map and Quick-Bird imagery are used for map revision. It also highlights the procedure of using GPS for picking the required geographic coordinates.

Contemporary cities, particularly in developing countries, experience an accelerating rate of changes and expansion. Such development has instigated the need for use of a fast technique that could adequately update the map of urban areas. This book demonstrates the application of Remote Sensing and Geographic Information System (GIS) in revising township map. It elucidates how a conventional map and Quick-Bird imagery are used for map revision. It also highlights the procedure of using GPS for picking the required geographic coordinates. Furthermore, it outlines the steps for georeferencing satellite imagery using Ilwis 3.1 and digitizing the roads and ward boundaries with ArcView 3.2a software. The technique is capable of detecting changes that occur in the road network and urban development over a period of time. Thus remotely sensed data is affirmed to be suitable and recommended for mapping and updating Township maps.
