| Abstract | This study applies and evaluates topographic correction methods to reduce radiometric variation dueto topography characteristics in rugged terrain. The aim of this study was to improve the capability ofsatellite images to generate more reliable land cover mapping using object-based classification. Severalsemi-empirical correction methods, which require the estimation of empirically defined parameters,were selected for this study. Usually, these parameters are estimated relying on a previous land covermap. However, in this work the correction methods were applied considering the unavailability of a pre-vious land cover map and the ease for implementation, so the main land cover type was used to estimatecorrection parameters to be applied to correct all land cover type. Landsat 5 TM image and topographicdata derived from SRTM (Shuttle Radar Topography Mission) over an area located in an agriculturalregion of southeastern Brazil were used. Land cover classification was carried out using an object-basedapproach, which includes image segmentation and decision tree classification. The evaluation of topo-graphic correction methods was based on: spectral characteristics expressed by standard deviation andmean values of spectral data within land cover classes; relationship between spectral data and solar illu-mination angle on the slope (cos i); object (segment) mean size; decision tree structure; visual analysis;and classification accuracy. Results show that the standard deviation of spectral data and the correlationbetween spectral values and cos i decreased after data correction, but not for all methods for some of thetested TM bands. The methods herein referred as Cosine, S1, Ad2S and SCS methods showed to increasethe standard deviation and the correlation compared to the uncorrected data, mainly for bands 1, 2 and3. Object mean size, in general, decreased after correction, except for C method. The effect on the objectsize showed to be related to a calculated standard deviation of adjacent pixels values. The decision treestructure given by the number of leaves also decreased after correction. The C, SCS + C and Minnaertmethods showed the highest performance, followed by S2 and E-Stat, with a general accuracy increasearound 10%. Land cover classification from uncorrected and corrected data differed in a large portion ofthe total studied area, with values around 29% for all correction methods. |
