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…

Road-based travel recommendation using geo-tagged images from social media
Geotagged photos on social media like Flickr explicitly indicate the trajectories of tourists. They can be employed to reveal the tourists’ preference on landmarks and routings of tourism. Most of existing works on routing searches from social media are based on the trajectories of GPS-enabled devices’ users. We attempt to propose a novel approach in…

Towards interoperability between data from technical sensors and human sensors (VGI)
The increasing availability of sensor devices has resulted in large volumes of sensor data, which has raised the issue of making these data fully discoverable and interpretable by applications and end-users. The idea of OGC Sensor Web Enablement (SWE) has addressed this issue by proposing a set of standards to enable accessibility of sensor data…

New tool for clustering and analyzing spatial data with Neural Networks and Neural Gas
A new tool for clustering and analyzing geographic data with artifical self-organizing neural networks (SOM) and the innovative Neural Gas (NG) algorithms has been made availabe. The free SPAWNN suite supports different spatial context models and it also establishes interactive linkage between the neural network and geographic maps. Notably it enables further the follow-up clustering…
