Integration of Authoritative and Volunteered Geographic Information for updating Urban Mapping: Challenges and Potentials
A recently published paper provides a bibliometric review between integration of authoritative and volunteered geographic information (VGI) for the specific purpose of cartographic updating of urban mappings. The adopted methodology was through a bibliometric survey of the literature published by Web of Science and Science Direct. The period was evaluated from 2005 to 2020 and…

Inferencing indoor room semantics using random forest and relational graph convolutional networks (deep learning)
Semantically rich maps are the foundation of indoor location‐based services. Many map providers such as OpenStreetMap and automatic mapping solutions focus on the representation and detection of geometric information (e.g., shape of room) and a few semantics (e.g., stairs and furniture) but often still neglect room usage. To mitigate the issue, a new published paper…

Introducing the humstats.heigit.org dashboard about Humanitarian Mapping in OpenStreetMap
Since 2010 organized humanitarian mapping has evolved as a constant and growing element of the global OpenStreetMap (OSM) community. With more than 7,000 projects in 150 countries humanitarian mapping has become a global community effort. Mappers have added more than 60 Million buildings to OSM through HOT’s Tasking Manager. That’s around 13% of all OSM…

MAN & MACHINE portrayed in the Forschungsmagazin “Ruperto Carola”
Can the human brain be described as a kind of machine – and, by extension, human memory as a time machine? What do software and the human mind have in common, and what are the ethical dilemmas involved in the use of artificial intelligence (AI)? Neurobiologist Hannah Monyer and geoinformatics expert Bernhard Höfle present talking…

Relationships between Incidental Physical Activity, Exercise, and Sports with subsequent Mood in Adolescents
Physical activity is beneficial for human physical health and well‐being. Accordingly, the association between physical activity and mood in everyday life has been a subject of several Ambulatory Assessment studies. This mechanism has been studied in children, adults and the elderly, but neglected in adolescents. It is critical to examine this mechanism in adolescents because…

GIScience for physical activity research
GIScience methods are becoming more and more widespread in different domains. A current review article under involvement of HeiGIT researchers discusses the potential of ambulatory assessments and GIScience approaches for physical activity research. The article is on of the outcomes of the 2nd International CAPA Workshop 2019 “Physical Activity Assessment – State of the Science,…
