The world is experiencing a rapid rate of urban expansion, largely contributed by the world 
population growth.  Other factors supporting urban growth include the improved efficiency in the 
transportation sector and increasing dependence on cars as a means of transport.   Some of the 
problems   attributed   to   the   urban   growth   are:   depletion   of   energy   resources,   water   and   air 
pollution; loss of landscapes and wildlife, loss of agricultural land, inefficient and inadequate 
social security and lack of employment or underemployment. 
Aerial photography is one of the popular techniques for analyzing, planning and minimizing 
urbanization related problems.  However, with the advances in space technology, satellite remote 
sensing has increasing been utilized in the analysis and planning of the urban environment. The 
current generations of earth observation sensors are producing data with high potential for use in 
scientific and technological investigations. This article outlines the strengths and limitations of 
potential remote sensing techniques for monitoring urban growth. 
The technical advances in remote sensing have not only increased the quantity of data but 
also   opened   up   new   opportunities   for   the   observation   of   the   earth  (Quattrochi  et  al.   2003). 
However, suitable techniques for extracting detailed and accurate information are still at their 
infancy stages (Coppin et al.  2004).
