This section aims to compare single optical data and sin-gle SAR data in terms of ISE to investigate the potential of SAR data in mapping impervious surfaces. Four sets of optical and SAR images in four different cities were employed in this section: Guangzhou, Mumbai, Sao Paulo, and Cape Town, which are located in tropical and subtropical regions. Landsat TM/ETM+ images and ENVISAT ASAR images in these cities were used as the optical and SAR images for the comparative ex-periment. Table 6.1 lists the optical and SAR images used in this section.
