Abstract Currently, many methods exist that utilise Light Detection and Ranging (LiDAR) data sets in the earth sciences. Methods for its application to ecological sciences are, however, limited. For example, the use of scattered data for tree detection and delineation is a needed improvement in LiDAR processing methods, as it holds the promise to provide ecologists with relevant information about forests. We have developed a RANdom SAmple Consensus (RANSAC)-based (Fischler and Bolles 1981) program, referred to as StarSac, which utilises the ‘depth’ found in LiDAR data for tree detection and delineation.
