LiDAR data have become indispensable for research in archaeology and a variety of other topographic applications. To derive products (e.g. digital terrain or feature models, individual trees, buildings), the 3D LiDAR points representing the desired objects of interest within the acquired and georeferenced point cloud need to be identified. This process is known as [...]

At long last, welcome to another addition of our How to become ohsome-series!
This one is special because we’re discussing a third-party application that uses ohsome API as back-end to accumulate historical OSM data. Although this innovation isn’t directly about our API, it’s close enough (and exciting enough) to merit inclusion and just one more opportunity for you [...]

Heidelberger Geoinformatiker machen im Projekt „SocialMedia2Traffic“ geokodierte Informationen nutzbar
Navigationsdienste benötigen aktuelle Verkehrsinformationen, um geeignete Routen zu ermitteln und die Fahrzeit möglichst genau zu berechnen. Dafür können nun auch frei zugängliche Daten aus Sozialen Medien und der Weltkarte OpenStreetMap genutzt werden. Ein entsprechendes System, mit dem sich aus ihnen die Verkehrsgeschwindigkeit abhängig von der Tageszeit [...]
