From 1997 to 2003, a wide data set about the old Ethiopian city of Harar, the most
important historical and cultural centre of the Islamic world in the Horn of Africa, was
collected and analysed using the latest geographic information technology. Precise geotopographical
description of the urban elements, significant artistic and historical features,
prevailing environmental conditions, and demographic and health particulars of the entire
resident population were linked closely together to draw a comprehensive portrait of the
ancient walled city.
