Streetscape Intelligence: GeoAI at Eye Level
Crowdsourced street-level imagery can be used to detect and map humanitarian-relevant features in near real time. We have developed a machine-learning-based analytical pipeline that integrates with the open-source imagery catalogue Panoramax to support a more flexible disaster response and urban monitoring, especially in underserved regions. This blog article was originally posted on Medium by Maciej Adamiak, machine…

openrouteservice use-case: enhancing sustainable travel in small cities and outer metropolitan areas
The ENHANCE project explores how 15-minute city principles can be applied beyond dense urban hubs, using mapping, behavioral research, and simulation tools to design more sustainable and inclusive mobility systems. The ENHANCE project, funded by Driving Urban Transitions to a Sustainable Future (DUT) under JPI Urban Europe, addresses the challenges of implementing 15-minute city (15mC)…

Enhancing OSM Data Quality Analysis: Thematic Accuracy of Land Cover in the ohsome Dashboard
Together with the German Federal Agency for Cartography and Geodesy (BKG) we released a new version of the ohsome dashboard, introducing a new indicator for assessing the thematic accuracy of land cover data in OpenStreetMap (OSM). This development is part of a broader project together with BKG on OSM data quality evaluation. New indicator: Thematic…

Advancing Disaster Preparedness in Madagascar with Data-Based Anticipatory Action
Anticipatory Action (AA) is becoming an increasingly vital approach in humanitarian and disaster risk management. By leveraging forecasts and risk data, AA enables timely interventions before extreme events occur. Geoinformation technologies play a key role in operationalizing this approach. In Madagascar, where cyclones regularly cause widespread damage, HeiGIT has been working with Croix-Rouge Malagasy (CRM,…

Unveiling the Climate Action Navigator Part 5 – CO₂ Budget
Thanks to the newest addition to the Climate Action Navigator, it is now possible to calculate the remaining CO₂ budget for several German cities (Berlin, Bonn, Hamburg, Heidelberg, and Karlsruhe) to stay within certain global warming limits (e.g. +1,5°C). The CO₂ Budget assessment tool also tracks if the city is on the right track to…

New paper “Mapping High-Resolution Carbon Emission Spatial Distribution Combined with Carbon Satellite and Multi-Source Data”
This study develops a framework integrating satellite observations with spatial proxy data to produce high-resolution urban carbon emission maps. The method is applied to Urumqi, China, demonstrating accurate and timely estimations compared with traditional inventories. Reducing carbon emissions is a global priority, but conventional inventory methods based on administrative statistics fail to capture fine-scale spatial…

New paper “Mitigating heat stress by reducing solar exposure in pedestrian routing”
Using Heidelberg as a case study, researchers modeled time-dependent solar exposure for the entire pedestrian network by combining high-resolution DEM/DSM building and vegetation data with OpenStreetMap road data. Adapting to heat stress in cities is a major challenge under global warming, as both climate change and the urban heat island effect increase health risks worldwide.…

New paper: Mapping energy poverty indices in urban scale: A case study of Santiago de Chile
This study evaluates the applicability of macro-scale energy poverty indices in an urban context, using Santiago de Chile as a case study. Energy poverty (EP), understood as the inability of a household to meet its basic energy needs, is a global challenge exacerbated by rising energy prices, inflation, and economic instability. Accelerated urbanization and climate…
