Shadow ReductionThis utility adjusts an RGB color composite image by lightening those pixels thatare shaded by terrain features. The method, like the DEM Haze Reductionalgorithm, uses the elevation information in a digital elevation model to correctthe RGB color image. Start by obtaining a matching DEM/RGB image set. Youcan use an ASTER DEM/Landsat set as described in Section 47. Once youhave created your matched set, open both files, first the RGB image and then theDEM. Select ‘Post Process’ | ‘Brighten Shadow Areas’ | ‘DEM Method’. Whenyou do the Shadow Adjust Data Entry Form will become visible.209
