Despite the unprecedented rate of urbanization around the world, information regarding land use planning
and management is not updated frequently enough to accurately track this urban change. In order to
monitor changes in the urban environment, an understanding of the change in patterns of urban development
over time is becoming increasingly important. The objective of this study is to explore an approach
for combining remote sensing and spatial metrics to monitor urbanization, and investigate the relationship
between urbanization and urban land use plans. The study areas, consisting of the cities of Hanoi,
Hartford, Nagoya and Shanghai, were examined using Landsat and ASTER data from 1975 to 2003. In this
study a program based on the PLADJ spatial metric was undertaken to produce urban growth maps. Then,
FRAGSTATS was used to evaluate the characteristics of urban composition. The results showed that the
urban core of Nagoya changed moderately over time. Shanghai had a high population density, and satellite
towns absorbed potential suburban development. Hartford exhibited a spread out pattern of urban
development with a high concentration of settlement in the suburb. Conversely, the new urban areas
of Hanoi developed rapidly along major transportation routes, resulting in urban development in Hanoi
assuming an unusual pattern. The combined approach of remote sensing and spatial metrics provides
local city planners with valuable information that can be used to better understand the impacts of urban
planning policies in urban areas, particularly in Hanoi.
