New Publication in “Nature Communication” on the unequal distribution of building data in OSM
Benjamin Herfort and his colleagues Sven Lautenbach, João Porto de Albuquerque, Jennings Anderson and Alexander Zipf published an article in the renowned journal Nature Communications (Impact Factor 2023: 17.7). In their article, they address the uneven distribution of OpenStreetMap data worldwide, which can have an impact on research results and humanitarian operations. They provide solutions…

OEV: Indicator Correlations (4/4)
After introducing the OSM Element Vectorisation Tool last week, we now want to show possible use cases and specific examples of what the tool can do. This third and last example will look at the correlations between indicators. The goal is to first assure that the indicators measure distinct data attributes and then search for interesting or…

OEV: Quantifying differences between imports (3/4)
After introducing the OSM Element Vectorisation Tool last week, we now want to show possible use cases and specific examples of what the tool can do. This second of three use cases (see use case 1) compares the data in the regions of Maribor, Slovenia and Ngaoundéré, Cameroon. Both regions are exceptionally well covered with land-use and land-cover information in OSM.…

OEV: Analysing attributes of remarkable elements (2/4)
After introducing the OSM Element Vectorisation Tool earlier this week, we now want to show possible use cases and specific examples of what the tool can do. This first of three use cases takes a closer look at the data in the region of Heidelberg, Germany. We will use the concept of archetypes to identify…

OSM Element Vectorisation Tool Version 1
The IDEAL-VGI research project is nearing its end. And while that won’t be the end of our research into social data sources, data quality analyses and land-use information, we are happy to announce a major outcome: the version 1 release of the OSM Element Vectorisation Tool (OEV). The tool was first presented to the public…

New Paper: Carbon Fluxes Related to Land Use and Land Cover Change in Baden-Württemberg
Featured Image: Figure 1. Total carbon fluxes related to LULCC in Baden-Württemberg between March 2018 and October 2019 (LaVerDi, OSMlanduse+), and March 2018 and March 2020 (OSMlanduse, OSMlanduse cleaned). The upper plot shows the relative difference of carbon fluxes [%] with respect to LULC transition and carbon flux attribution method. The carbon fluxes of method…

Private Vehicles Greenhouse Gas Emission Estimation at Street Level for Berlin Based on Open Data
Since the transportation sector is one of the major greenhouse gas (GHG) emitters that has not seen significant emission reductions in the last decades, it requires special attention from policymakers. However, estimations of traffic emissions often rely on huge amounts of actual traffic data whose availability is limited. Therefore, Ulrich et al. now propose an…

Functionality Update for OSM Landuse Landcover
We are pleased to announce that https://osmlanduse.org has received a functionality update. Thanks to the cooperation of GIScience and HeiGIT under the IDEAL-VGI project, our researchers were able to add a number of new features to the interactive map. The map displays OSM land-use and land-cover information. The two different data layers that made up…

Activation of the Disaster Portal for the earthquake in Türkiye/Syria
During catastrophic events such as the recent Türkiye/Syria earthquake, the road infrastructure in the affected area is often widely interrupted and accessibility varies over time. Inspite of this, it is imperative to quickly provide assistance to the affected people. Humanitarian Organizations need real-time information for force and logistics planning: Which roads are still passable? How…
