A Volunteered Geographic Information Framework to Enable Bottom-Up Disaster Management Platforms
ISPRS International Journal of Geo-Information, 2015 Recent disasters, such as the 2010 Haiti earthquake, have drawn attention to the potential role of citizens as active information producers. By using location-aware devices such as smartphones to collect geographic information in the form of geo-tagged ...

Propagation of Uncertainty for Volunteered Geographic Information in Machine Learning (Short Paper)
, 2018 Although crowdsourcing drives much of the interest in Machine Learning (ML) in Geographic Information Science (GIScience), the impact of uncertainty of Volunteered Geographic Information (VGI) on ML has been insufficiently studied.

Transactions in GIS, Volume 30, Issue 3, May 2026.ABSTRACT In crowdsourcing, dividing work into narrowly defined microtasks may affect the quality of the final product. This study examines this problem in the con text of humanitarian mapping initiatives coordinated using the Humanitarian OpenStreetMap Team Tasking Manager, analyzing 4619 projects and over 1.4 million microtasks. Using a combination of

Extraction of Pluvial Flood Relevant Volunteered Geographic Information (VGI) by Deep Learning from User Generated Texts and Photos [PDF]
ISPRS International Journal of Geo-Information, 2018 In recent years, pluvial floods caused by extreme rainfall events have occurred frequently. Especially in urban areas, they lead to serious damages and endanger the citizens’ safety. Therefore, real-time information about such events is desirable.
