András Zlinszky is a biologist and remote sensing scientist, working with the Department of Geodesy and Geoinformation of the Vienna University of Technology, and the Centre for Ecological Research of the Hungarian Academy of Sciences. He finished his PhD in 2013.
This study was carried out in the framework of the Changehabitats2 project for developing airborne remote sensing in support of ecological conservation mapping for the EU Habitat Directive. Airborne Laser Scanning (ALS) data are of interest for ecological mapping, but conventional single-parameter rendering of such point clouds is not intuitive and does not support interpretation of vegetation parameters. This poster presents a new multi-parameter visualization scheme, assigning three main laser scanning data attributes (Echo Amplitude, Echo Width and Normalized Height) to the three primary colour channels. This enhances the information content of the point cloud and allows identification of various vegetation features.
