Maps of the spatial distribution of crop heights can strongly support agriculture in terms of efficiency and yield optimization. Recently published results of experiments of the 3D Spatial Data Processing research group describe an approach to easily extend regular agricultural machines with low-cost sensors for capturing crop heights while the machine is in the field.
Based [...]

In September 2017, the 3D Spatial Data Processing Group (3DGeo) joined the German-Russian expedition of the Alfred Wegener Institute (AWI) for Polar and Marine Research to the Arctic research station Samoylov (N 72°22’, E 126°29’) in the central Lena Delta.
Under the lead of Julia Boike, the research team maintained and expanded long-term monitoring stations and [...]

LiDAR meets Art

An interesting 3D art project using point clouds of the 3D Spatial Data Processing research group of Prof. Bernhard Höfle (3DGeo) was recently realized by artist Gerrit Frohne-Brinkmann. The data were acquired from natural karst cave features in the Dechen Cave near Iserlohn, Germany both with a low-cost Kinect sensor and terrestrial LiDAR.
For the art [...]

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 measurement [...]

In agriculture, information about the spatial distribution of crop height is valuable for applications such as biomass and yield estimation, or increasing field work efficiency in terms of fertilizing, applying pesticides, irrigation, etc. Established methods for capturing crop height often comprise restrictions in terms of cost and time efficiency, flexibility, and temporal and spatial resolution [...]

The results of a study dealing with photogrammetric 3D geodata of mass wasting sites conducted at the GIScience were considered to be worth publishing in the Journal of Applied Remote Sensing: ‘Terrestrial and unmanned aerial system imagery for deriving photogrammetric three-dimensional point clouds and volume models of mass wasting sites.‘
Three-dimensional (3D) geodata of mass wasting [...]
