Primena multispektralnih senzora u kvantifikovanju Koeficijenta Uređenosti Sliva (Xa) u Metodi Potencijala Erozije

Abstract

In this paper, Soil Protection Coefficient (Xa) was quantified through the approach of high resolution multispectral orthomosaic segmentation and classification. The approach was presented in the example of ski lane in ski center Kopaonik. The data collection was performed through application of Unmanned Aerial System equipped with 5band multispectral sensor and RGB sensor. Data processing was performed with digital photogrammetric and Object Based Image Analyses software. The Soil Protection Coefficient represents the descriptive and very sensitive parameter of Erosion Potential Method. Application of 5 spectral bands, of which 2 bands are very sensitive to the type of land use /land cover allowed precise detection, delineation and classification of different land cover/use types. These types were directly tied to the values of Xa coefficient which were originally proposed by the author of the Erosion Potential Method, professor Slobodan Gavrilović. The final result was a georeferenced digital map classified with both land cover/use and Xa values classes. This approach created the potential to use such maps for further analyses, planning, and modeling of erosion protection measures.
