First, following preprocessing and registration of 2006 imagery to the topography at the scale of 1:50,000, the TM image of 2006 was segmented and classified by using object-oriented...
By exploiting high resolution airborne LiDAR data along with color infrared aerial photographs, this research aims to quantify the urban landscape components using an object-based two-stage method in the case of downtown Houston, Texas, USA. The urban landscape components will be identified and classified by integrating spectral information from color infrared aerial photograph and surface geometric...
