Zusammenfassung
Rapid uncontrolled urban growth over last twenty years creates significant pressures for the environment and many
challenges for urban planning in Ho Chi Minh City (HCMC). One of the big challenges is land management. The
application of remote sensing can provide reliable and current geodata bases for land management and land use monitoring
in HCMC. In this study we used Landsat Imagery to detect and analyse the land cover change HCMC for the
periods 1989 2000, 2000 2002 and 2002 2005 in order to find out the extent of the urban growth in HCMC in
these time periods. The next important task is to evaluate the urban growth regarding well known urban planning
principles like the compact city or the city of short distances . This will be done by mean of urban density gradient ,
the jaggedness degree and the centre oriented entropy developed by Thinh (2004). Our results show the
dimension of urban expansion in HCMC and the potential of the linkage between remote sensing techniques and urban
form metrics as a powerful and useful tool for modern land use change monitoring. They are very useful for the
investigation of growth patterns and land use planning in HCMC.
