The urban expansion monitoring of Wuhan city using multitemporal remote sensing images

City is a huge and complicated system. People around the world are paying strong attention to the development of cities. This paper uses Wuhan as the study area and uses Landsat TM images acquired in 2002, 2005 and 2010 respectively as the basic data. Based on object-oriented image analysis approach, the land use information is extracted firstly, and then the urban expansion of Wuhan city during last decade is analyzed with the urban expansion intensity index, the quadrants position analysis and the overall pattern analysis. From the result we can see that the pattern of urban expansion of Wuhan is a combination of ribbon expansion and centralized concentric expansion. And the scale of the expansion is under control.
