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…
Earlier this month, the Association of Geographic Information Laboratories in Europe (AGILE) held its 2023 conference, and GIScience and HeiGIT team members contributed presentations, analyses and papers toward this year’s…
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…
![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 1 are set to 0. The lower plot shows the total absolute carbon fluxes [Mg C] calculated with carbon flux attribution method 1 with respect to LULC transition and LULCC method.](https://heigit.org/wp-content/uploads/2023/05/ed501d68-7952-4263-a23e-a5f8a81fa7a4-768x873.png)

Natural hazards threaten millions of people all over the world. To address this risk, exposure and vulnerability models with high resolution data are essential. However, in many areas of the…
Volume 26, Issue 8 of Transactions in GIS, published in December 2022, has a cover story and it’s us- well, our article anyway. Besides uniting our love of math, mapping,…

Over the last two years, we have witnessed the ever-fast growth of micro-mobility services (e.g., e-bikes and e-scooters), which brings both challenges and innovations to the traditional urban transportation systems….
Humans rely on clean water for their health, well-being, and various socio-economic activities. During the past few years, the COVID-19 pandemic has been a constant reminder of about the importance…
Large-scale mapping activities can benefit from the vastly increasing availability of earth observation (EO) data, especially when combined with volunteered geographical information (VGI) using machine learning (ML). High-resolution maps of…
The availability of data on public transport is a prerequisite for numerous spatial data applications such as routing, accessibility analyses or route planning. OpenStreetMap (OSM) – as a global platform…
Recently, a new research paper “Detecting OpenStreetMap missing buildings by transferring pre-trained deep neural networks” (Pisl, J., Li, H., Herfort, B., Lautenbach, S., Zipf, A. 2021) has been accepted at…
We are pleased that our research paper “Deriving indicators for Points of Interest and analyzing mixed activities in urban areas” (Ullah, Lautenbach, Zipf 2021) has been accepted at the 12th…
The impact of climate change is particularly strong in higher latitudes. The Arctic is currently warming up at a much higher pace than the global average. This leads to thawing…
Public urban green spaces are important for the urban quality of life. Still, comprehensive open data sets on urban green spaces are not available for most cities. As open and…
Online knowledge projects such as OpenStreetMap (OSM) and Wikipedia have gained high importance, trust and even economic value. These projects and their content are maintained and enhanced by online communities…
As a user‐generated map of the whole world, OpenStreetMap (OSM) provides valuable information about the natural and built environment. However, the spatial heterogeneity of the data due to cultural differences…
Land use decision involve trade-off with respect to the ecosystem service produced by the different land use systems. Agricultural use versus natural ecosystems is the main alternative for which trade-offs…
