Online data viewer: Heidelberg’s tallest trees
Two weeks ago, we conducted a field campaign in the frame of a 3DGeo Sensor Practical course to acquire 3D point clouds of Heidelberg’s tallest trees, Sequoias planted in the Arboretum I (see our blog post). Today, we present the prepared data in our new online point cloud viewer based on potree: https://3dweb.geog.uni-heidelberg.de/potree/scenes/sequoia.html A few…

M3C2-EP: Pushing the limits of 3D topographic point cloud change detection by error propagation
In our efforts to improve change detection and quantification in time series of 3D point clouds, we have published yet another milestone. Our paper, titled M3C2-EP: Pushing the limits of 3D topographic point cloud change detection by error propagation, presents a novel method to better separate noise from actual change in point clouds sensed with…

Automatic building detection with ohsome2label and Tensorflow
Accurate and complete geographic data of human settlement is crucial for humanitarian aid and disaster response. OpenStreetMap (OSM) can serve as a valuable source, especially for global south countries where buildings are largely unmapped. In a previous blog, we introduced our recent work in detecting OpenStreetMap missing buildings, so this time we will show you…
