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.…

3D Sensor Practical
In June 2025, Ronald Tabernig and Hannah Weiser, researchers in the 3DGeo Research Group (Prof. Bernhard Höfle), held the annual 3D sensor practical, a two-day practical field course which took place in two exciting study sites close to Heidelberg: Our students learnt: Since we surveyed the same study sites last year, students will be able…

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…
