A physically-based model to correct atmospheric and illumination effects in optical satellite data of rugged terrain
نویسندگان
چکیده
A physically-based model to correct atmospheric and topographically induced illumination effects in optical satellite data is developed and tested. Special emphasis is put on the impact of rugged terrain. Ground reference data for various land use classes enables the assessment of the corrections' influence on land use classifications. The estimation of surface reflectance is achieved in a two-step procedure. First irradiance components and atmospheric parameters are calculated for horizontal surfaces using the atmo-code 6S [1], then the influence of the topography on the parameters is integrated using DEM data.

A Model of Topographic Correction and Reflectance Retrieval for Optical Satellite Data in Forested Areas
Topographic correction is a necessary step of pre-process in the remote sensing application in rugged terrain. Most of traditional topographic correction methods are empirical and statistical based. These methods have the advantage of facility; however they also have some disadvantages, such as lack of comprehensive physical analysis, subjectivity in operation, separation of atmospheric correct...
متن کاملSpectral Signature of Alpine Snow Cover from the Landsat Thematic Mapper
M a p p i n g of snow and estimation of snow characteristics from satellite remote sensing data require that we distinguish snow from other surface cover and from clouds and compensate for the effects of the atmosphere and rugged terrain. The spectral signature of the snowpack is calculated from a radiative transfer model accounting for scattering and absorption by the ice grains, water inclusi...
متن کاملEvaluation of Satellite Image Correction Methods Caused by Differential Terrain Illumination
The problem due to differential terrain illumination on satellite imagery is experienced by most of areas which are on mountainous terrain. This may cause variations in reflectance of similar ground features which lead to a misclassification of land cover classes due to different topographic positions. This phenomenon most commonly occurred in the areas which are located on southern and norther...
متن کاملPractical Illumination Correction of Satellite Imagery in Consideration of Anisotropic Skylight Component
In satellite images over rugged terrain, we can find some topographic effect entangled with atmospheric effects [1]. Without correcting these effects, it is difficult to evaluate the satellite images for land cover classification or multi-temporal monitoring of natural environment. Iikura[2] derived a unified simple correction formula (DN − B)/(cosβ + C) from a physical model of signal detected...
