Abstract

Fine scale land cover classification of urban environments is important for a variety of applications. LiDAR data has been increasingly used, separately or in conjunction with other remote sensing data, for providing land cover classification due to its high geometric accuracy as well as its additional radiometric information. An important issue in the classification of remote sensing data is the inevitable imbalance of training samples, which usually results in poor classification performance in classes with few samples (minority classes). In this paper, a synergy of sampling techniques in data mining with ensemble classifiers is proposed to address the data imbalance problem in the trainin..
