Correction of atmospheric and topographic effects for high spatial resolution satellite imagery

摘要: A method for the combined correction of atmospheric and topographic effects has been developed. It accounts horizontally varying conditions also includes height dependence radiance transmittance functions to simulate simplified properties a threedimensional atmosphere. Digital Elevation Model (DEM) is used obtain information about surface elevation, slope, orientation. Based on Lambertian assumption reflectance in rugged terrain calculated. The restricted high spatial resolution satellite sensors like Landsat TM SPOT HRV, since some simplifying assumptions are being made reduce required image processing time. possibilities limitations critically discussed.
