New Paper in gis.SCIENCE: 3D Laser Scanning Point Clouds and GIS – Current Developments
|The LiDAR Research Group Heidelberg, Chair of GIScience, University of Heidelberg, has published a new paper in the journal gis.SCIENCE contributing to scientific field of "3D Laser Scanning Point Clouds and GIS – Current Developments". The article is written in German with original title "3D Laserscanning Punktwolken und GIS - Aktuelle Entwicklungen".
In recent years laser scanning has evolved into an established and widely-used method for the three-dimensional acquisition of the Earth surface. The primary product of laser scanning is an unorganized 3D point cloud of the scanned objects and the underlying ground surface. This paper gives an overview of possible combinations of GIS and laser scanning software in order to extract valuable geoinformation from the original laser point cloud. Based on two specific examples – i) solar potential analysis and ii) vegetation detection – the combination of GIS functionality and point cloud algorithms is investigated in detail. It is shown that point cloud analysis has major advantages for a great variety of applications compared to raster-based GIS approaches, particularly for the investigation of vertical structures (e.g. building walls and noise barriers) as well as vegetation. Furthermore, insight is given into current and future research challenges dealing with the integration of laser scanning point clouds and respective analysis tools in service-oriented architectures of the GeoWeb.
