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…

OSM Changeset Analysis with Humstats and the ohsome Framework
In this blog post we want to take a closer look at a fruitful mapping collaboration between humanitarian organizations and corporations. Since 2015 mapping remote areas in OSM is one part in the cooperation between the leading savings, retirement and insurance company, Aviva, and the British Red Cross (BRC). By combining multiple datasets we analyzed…

Openrouteservice for complex route optimization in new QGIS extension by Regionalverband Ruhr
(Deutsche Version unten) The Regionalverband Ruhr (Team 9-2 Geodata Technology) has used the potential of HeiGIT’s openrouteservice (ORS) in a new QGIS extension and thereby created another possible application for the ORS: The tool “Location and Route Optimization of Addresses” allows to search and locate addresses and to find the optimal routes between them. This…
