The OpenStreetMap folksonomy and its evolution
The comprehension of folksonomies is of high importance when making sense of Volunteered Geographic Information (VGI), in particular in the case of OpenStreetMap (OSM). So far, only little research has been conducted to understand the role and the evolution of folksonomies in VGI and OSM, which is despite the fact that without a comprehension of…

Open land cover from OpenStreetMap and remote sensing
In a recently published study (1), we produced a web based land use land cover (LULC) product based on OSM tags which are constantly updated by contributors/volunteers, and present a Remote Sensing based solution when tags were absent for a test site. We harness the combined benefit of an open source and ever-growing machine generated…

Study “Multiscale analysis and reduction measures of urban carbon dioxide budget based on building energy consumption” published
The 3D spatial data processing group had the opportunity to collaborate with the team of Prof. Tzu-Ping Lin from National Cheng Kung University, Tainan, Taiwan, within the frame of a study dealing with carbon emission reduction measures in urban environments. One option of reducing carbon emission by buildings is to install photovoltaic (PV) panels in…

Determination of building inundation depths based on user-generated flood images – new study published
In our recently published study “Direct local building inundation depth determination in 3-D point clouds from user-generated flood images” we present a new approach for deriving local building inundation depth from ordinary user-generated flood images captured during a flood event. After reconstructing a 3-D scene of the building of interest with close-range photogrammetry (CRP) algorithms,…

3D bathymetry measurements in shallow-water environments with a low-cost sensor – study published
To take bathymetric measurements in areas with shallow water is very challenging for methods such as SONAR or bathymetric LiDAR. In our study “Assessing the Potential of a Low-Cost 3-D Sensor in Shallow-Water Bathymetry”, we examine the performance of a low-cost 3D camera when capturing bathymetry in waters up to 0.4 m depth. The tested…
