Studying on the trend of spatial expansion of urban in Hohiminh city, which used remote sensing and spatial analysis of GIS, has revealed changes of spatial urban over times.. Analysis of spectral response for main land cover types had been done on Landsat data from 1975 to 2005 in order to discriminate urban type with the others. Based on this spectral analysis, the expansion of urban area over times has been identified. Spatial statistics analysis was applied to estimate trends of urban area of Hochiminh city. Tthe results showed a wide spreading out from 1975 to 2008, the urban area has been extended two times in radius and three times in area. The trends of spatial expansion is anisotropic. There is a spatial expansion trend in the north east-south west axis.
