Identification of Forested Landslides Using LiDar Data, Object-based Image Analysis, and Machine Learning Algorithms

open access: yesRemote Sensing, 2015
For identification of forested landslides, most studies focus on knowledge-based and pixel-based analysis (PBA) of LiDar data, while few studies have examined (semi-) automated methods and object-based image analysis (OBIA).
