Figure 5-5. Enhancement of roughnes and topography: (a) SIR-A image of the Santa Ynez Mountains in California obtained at about a 50-deg incidence angle - at this angle, surface roughness effects dominate the image; (b) Seasat image of the scene in (a) obtained at about 20-deg incident angle- at this small angle, topography is enhanced because the slopes are closer to this small value. Illumination is from the bottom in (a) and from the lower left corner in (b)
