Introducing ohsome2label tool to generate training samples from OpenStreetMap for geospatial deep learning

After more than a decade of rapid development of volunteered geographic information (VGI), VGI has already become one of the most important research topics in the GIScience community. Almost in the meantime, we have witnessed the ever-fast growth of geospatial deep learning technologies to develop smart GIServices and to address remote sensing tasks, for instance,…

Exploration of OpenStreetMap Missing Built-up Areas using Twitter Hierarchical Clustering and Deep Learning in Mozambique

Accurate and detailed geographical information digitizing human activity patterns plays an essential role in response to natural disasters. Volunteered geographical information, in particular OpenStreetMap (OSM), shows great potential in providing the knowledge of human settlements to support humanitarian aid, while often the availability and quality of OSM remains a major concern. The majority of existing…

Analysing OSM Completeness of health facilities in Sub-Sahara Africa in ohsomeHeX

A new map in ohsomeHeX provides an overview of areas in Sub-Sahara Africa where information on health facilities is still missing in OpenStreetMap (OSM). The completeness of OSM is measured by comparing to a reference dataset on public health facilities in Sub-Sahara Africa, which was developed by Maina et al. 2019. Especially in these days,…

Volunteered Geographic Information research in the first decade: a narrative review of selected journal articles in GIScience

More than 10 years have passed since the coining of the term volunteered geographic information (VGI) in 2007. A recently published article presents the results of a review of the literature concerning VGI. A total of 346 articles published in 24 international refereed journals in GIScience between 2007 and 2017 have been reviewed. The review has…

Behavioural Effects of Spatially Structured Scoring Systems in Location-Based Serious Games – A Case Study in the Context of OpenStreetMap

Location-based games have become popular in recent years, with Pokémon Go and Ingress being two very prominent examples. Some location-based games, known as Serious Games, go beyond entertainment and serve additional purposes such as data collection. Such games are also found in the OpenStreetMap context and playfully enrich the project’s geodatabase. Examples include Kort and…

Detecting OSM Building Facades with Graffiti Artwork Based on Street View Images and Social Media using Deep Learning

As a recognized type of art, graffiti is a cultural asset and an important aspect of a city’s aesthetics. As such, graffiti is associated with social and commercial vibrancy and is known to attract tourists. However, positional uncertainty and incompleteness are current issues of open geo-datasets containing graffiti data. In a newly published paper, we…
