摘要：The most dynamic region on earth is the urban areas. Their size has been constantly increased during the past and this process will go in future. In less develop countries a strong trend toward concentration of people in urban areas can be observed. To understand urban growth, remote sensing imagery is a reliable source. Potiskum local government with its headquater in Potiskum town is one of the local governments which has the highest population in Yobe state. The need to determine the rate at which the area grow necessitate the application of remote sensing and GIS technique in assessing the urban growth between 1999 and 2018. Land sat 7 ETM+ satellite image of 1999, 2008, and Landsat 8 OLI of 2018 were processed using Arc GIS 10.6 and ERDAS imagine 2014 for analyzing the urban growth. The entire area was classified into four classes that is water body, settlement, bare soil and farmland. The result revealed that within the period of research, there is an increase in settlement and farmland class by 3.42% and 0.44% respectively and a decrease in water body by 0.35% and 3.51% respectively. The accuracy assessment was carried out for the four classified map and it revealed that the overall accuracy and Kappa statistic were 91% and 0.8% respectively. The study provide an insight into understanding of urban growth and aids in subsequently infrastructure planning management and decision making.
