Laser scanning campaign at UNESCO World Heritage Site Lorsch Abbey
On Wednesday, 19th of March, the Kings Hall (Torhalle) facades at UNESCO World Heritage Site Lorsch Abbey were captured in 3D with a terrestrial laser scanner Riegl VZ-400 (provided by the Chair of GIScience) by Martin Hämmerle (LiDAR Research Group). The produced data set consists of about 65 million laser points and will allow for…

New Release of LVISA – Exploring 3D Point Clouds of Trees in the Web
The LIDAR Research Group (LRG) released LVISA – a novel system for analyzing point clouds of vegetation. This system examplifies a web-based laser scanning database for the management and analysis of tree reference signatures. It combines techniques and methods of LiDAR and 3D GIScience. We present a new release of LVISA including re-designed and re-implemented…

New video online: 3D solar potential assessment for renewable energy supply
Watch the video: http://youtu.be/TaCUaG5XEas We use methods like laser scanning and GIS in combination with computer science to simulate the sun’s path and the respective shadows that are cast by 3D objects. Thereby, we can assess the solar potential for certain areas and surfaces. Solar potential assessments can play a crucial role in studies that…

Fusion of human and remote sensor data in urban environments
OpenStreetMap (OSM) currently represents the most popular project of Volunteered Geographic Information (VGI): geodata are collected by common people and made available for public use. Airborne Laser Scanning (ALS) enables the acquisition of high-resolution digital elevation models that are used for many applications. Our new study combines the advantages of both ALS and OSM, offering…

About identifying man-made objects from mobile LiDAR data
A new automated approach for the detection and classification of man-made objects in urban corridors from point clouds acquired by vehicle-borne Mobile Laser Scanning (MLS) has recently been suggested by Fan and Yao. The approach is designed based on a-priori knowledge in urban areas: (i) man-made objects feature geometric regularity like vertical planar structures (e.g.…

Multi-Sensor Survey of Limestone Quarry
Researchers of the GIScience group (Institute of Geography, University of Heidelberg) captured parts of the limestone quarry of HeidelbergCement in Nussloch near Heidelberg in cooperation with the Unmanned Aerial Systems (UAS) developing company MAVinci. The aim of analysing the data is to find a cost-effective, time-saving but precise method to survey a quarry, including volume…
