The “TdLab Geography” (Dr. Nicole Aeschbach) developed a “Decarbonization Lab” as part of the course “Climate Science and its Implications” taught by Prof. Dr. Werner Aeschbach at the Heidelberg Physics Graduate Days at Heidelberg University. About 50 doctoral students of the Heidelberg Graduate School of Fundamental Physics (HGSFP) worked on creative and effective measures as [...]

The OpenStreetMap History Database (OSHDB) is what powers most of the functionality of HeiGIT’s ohsome platform. The ohsome API for example, which was often showcased here in the blog, is built on top of the OSHDB. Just recently, an open access software article about the OSHDB was published. Check it out to find out [...]

The New York Times + openrouteservice

In a recent article by the NYTimes the openrouteservice API isochrones interface was consumed to derive regions of reachability from subway stations in New York City. Their findings show that two-thirds of 550.000 residents who have difficulty walking live far from an accessible subway station. Head over to this very interesting analysis which you can find [...]

Topographic parameters of high-resolution digital elevation models (DEMs) with meter to sub-meter spatial resolution, such as slope, curvature, openness, and wetness index, show the spatial properties and surface characterizations of terrains. The multi-parameter relief map, including two-parameter (2P) or three-parameter (3P) information, can visualize the topographic slope and terrain concavities and convexities in the hue, [...]
