A case study on the relation between city planning and urban growth using remote sensing and spatial metrics
Despite
the unprecedented rate of urbanization around the world, information
regarding land use plan-ning andmanagement is not updated frequently
enough to accurately track this urban change. Inorder to
monitor changes in theurbanenvironment, anunderstandingof the change
inpatterns of urbandevelop-ment 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 relation-ship 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 spatialmetricwas undertaken toproduce
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 satel-lite 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

Inorder to monitor changes in theurbanenvironment, anunderstandingof the change inpatterns of urbandevelop-ment 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 relation-ship 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.
