Land use classification based on the intensity value of the reflected laser beam : Klasifikacija rabe površin iz vrednosti intenzitete

Abstract

Airborne laser scanning of a terrain results, in addition to polar coordinate measurements, in intensity measurement of the reflected laser beam. Because the 3D lidar point cloud itself does not include information about the object types on which points are located,intensity measurements provide the important data for identification of objects and phenomena in the physical space. This is confirmed by the colour coded intensity value image, where particular objects (asphalt road, grass, building etc.) can be recognized. The measuredintensity values have been analyzed within the Neusiedler See project case, part of a transnational project SISTEMaPARC (Interreg IIIB). We have investigated the land use classes that could bedifferentiated on the basis of intensity values thus enabling the land use classification.
