The potential of Volunteered Geographic Information (VGI) in future transport systems [PDF]
Urban Planning, 2016 As transport systems are pushed to the limits in many cities, governments have tried to resolve problems of traffic and congestion by increasing capacity. Miller (2013) contends the need to identify new capabilities (instead of capacity) of the transport

The utility of using Volunteered Geographic Information (VGI) for evaluating pluvial flood models [PDF]
Science of The Total Environment, 2023 Pluvial floods are increasingly threatening urban environments worldwide due to human-induced climate change. High-resolution, state-of-the-art pluvial flood models are urgently needed to inform climate change adaptation and disaster risk reduction measures but are generally not empirically tested because of the rarity of local high-intensity ...

Peran Sistem Volunteered Geographic Information (VGI) Sistem dalam Pengurangan Risiko Bencana: Konsep dan Implementasi [PDF]
Jurnal Alami : Jurnal Teknologi Reduksi Risiko Bencana, 2020 There have been a lot of geospatial technologies implemented to support disaster management into a more effective way and achieve disaster risk reduction. One of these technologies is the use Volunteered Geographic Information (VGI). VGI refers to the volunteered activities by anyone to create geographic information.

Cartography and Geographic Information Science, 2023 Volunteered geographic information (VGI) offers a solution to inequalities in authoritative map data that can limit our response to humanitarian crises. However, sustaining voluntary contributions of map data can be difficult and hybrid machine learning-VGI (ML-VGI) workflows developed to encourage sustained volunteer contributions have been ...

Validating the Quality of Volunteered Geographic Information (VGI) for Flood Modeling of Hurricane Harvey in Houston, Texas [PDF]
Hydrology, 2023 The primary objective of this study was to examine the quality of volunteered geographic information (VGI) data for flood mapping of Hurricane Harvey. As a crowdsourcing platform, the U-Flood project mapped flooded streets in the Houston metro area. This research examines the following: (1) If there are any significant differences in water depth (WD ...

Maps, volunteered geographic information (VGI) and the spatio-discursive construction of nature
Digital Geography and Society, 2022 This paper interrogates the role that spatial media such as maps and Volunteered Geographic Information (VGI) play in the construction and mobilisation of representations of nature. Drawing on poststructural political ecology, critical cartography, and GIScience, this article engages maps and VGI as discursive mechanisms that solidify and convey ...

, 2014 Volunteered Geographic Information (VGI) represents a valuable source of information. At the same time this data presents new data quality issues such as credibility. In this paper, we investigate the integration of VGI in Spatial OLAP (SOLAP) systems, which allow analyzing huge volume of geographic datasets. By means of a real case study, we highlight
