Forest height is an important indicator for forest biomass. Stereo imagery is sensitive to the vertical structure of forest. However, the result directly derived from stereo imagery is digital elevation model. The ground surface elevation under forest canopy is needed to derive forest height from stereo imagery. Considering the penetration abilities of L-band SAR data, the combination of stereo imagery...
Some researches in the field of surveying and mapping showed that it held potentials to derive vegetation height from stereo imagery. However, most of current researches were conducted on aerial images or spaceborne images with very high resolutions (about 0.5m). The resolution of stereo sensors with global coverage is always not so high. The characteristics of digital surface models (DSMs) should...
