As repeatedly stated by many researchers, the phenomenon of volunteered geo-graphic information (VGI) is an important new technological tool that can contribute to disaster management (DM). Specifically regarding floods, despite that there is very interesting published research work that assesses VGI and flood event management in various areas of the world, related research in Greece, is still limited. Moreover, the necessity of creating meaningful maps and graphs is still a significant challenge glob-ally, along with the general need to reduce the time needed for data processing. Cur-rent research presents steps towards those issues, by advancing various innovative initial methods and techniques that have been presented previously. The floods of Kalamata, Messinia (Greece, September 2016) were selected for case study, while as a VGI source, a corpus of 111000 tweets, published within 120 hours since the flood event occurrence, was used. As far as the methodology is concerned, the main steps, included: a. the classification of the tweets in categories, the main of which were: i) flood tracking, ii) tracking of consequences, iii) simple identification of rain and iv) irony/emotions. The next step was related to geo-referencing the classified infor-mation, by using an R script, while the final steps were linked to generating maps and graphs, from subsets of the processed data. The outcome of this research is based on the analysis of about 45% of the total dataset.

“…tradicionalni izvori podataka mogu pružiti kvalitetnu podršku u odlučivanju, no možda neće pravodobno pružiti ažurne ili obuhvatne podatke. VGI popunjava ovu prazninu dopuštajući građanima, volonterima i pogođenim zajednicama da doprinesu svojim lokalnim znanjem, zapažanjima i podacima putem različitih online platformi, mobilnih aplikacija i kanala društvenih medija [4], [5]. Koncept VGI nudi vrijednu perspektivu za obogaćivanje geoinformacija, pogotovo u slučajevima kriznih situacija gdje obično prevladava visoka motiviranost pojedinaca [6].…”

The escalation of disasters around the world has led to an increase in applied research in the service of developing technologies that support decision-making processes in crisis situations. Effective disaster management depends on the availability of up-to-date and accurate data, and the advent of Volunteered Geographic Information (VGI) has opened up opportunities for near-real-time data collection. VGI is produced by different stakeholders using different technologies and tools, each providing data with different levels of granularity and accuracy. In addition, the stakeholders themselves have a wide range of quality assessment methods and decision-making approaches, making it difficult to interpret their contributions. This review therefore aims to closely examine the research literature in the field of VGI in the context of disaster management, focusing on the quality dimensions of VGI that encompass both quality assurance and assessment aspects.

“…Availability of timely information in disaster management is still a challenge to planners, decision makers, and rescue authorities. VGI as updated geographical information of the area is rendered as one of the solutions to timely feed data in disaster-management systems [26][27][28][29][30][31]. A framework has been proposed by [32] to effectively use the value of VGI for disaster management to support the authoritative data in the context of SDI.…”

Spatial data infrastructures (SDIs) have been implemented for the last four decades in most countries. One of the key objectives of SDIs is to ensure the quick availability and accessibility of spatial data. The success of SDI depends on the underlying spatial datasets. Many developing countries such as Pakistan are facing problems in implementing SDI because of the unavailability of spatial data. Volunteered Geographic Information (VGI) is an alternate source for obtaining spatial data. Therefore, the question is what factors hamper the adoption of VGI for making it part of SDI in Pakistan. The intention behind this paper is to explore such factors as the key research question. To do so, we make use of the Technology–Organization–Environment (TOE) framework along with the partial least square structural equation model (PLS-SEM) to empirically analyze the factors impeding VGI from becoming part of SDI in the country. The study concludes that many technical, organizational, and environmental factors affect the adoption of VGI to be part of SDI in Pakistan.
