Understanding population fluctuations through volunteered geographic information and novel indicators: The experience of Rakiura, Stewart Island, New Zealand. GeoComputation 2019 Mathew Darling Ben Adams Caroline Orchiston Thomas Wilson Brendon Bradley 10.17608/k6.auckland.9846323.v2 https://auckland.figshare.com/articles/conference_contribution/Understanding_population_fluctuations_through_volunteered_geographic_information_and_novel_indicators_The_experience_of_Rakiura_Stewart_Island_New_Zealand/9846323 <div>In an era of heterogeneous data; novel methods and volunteered geographic information provide opportunities to understand how people interact with a place. However, it is not enough to simply have such heterogeneous data, instead an understanding of its usability and reliability</div><div>needs to be undertaken. Here, we draw upon the case study of Rakiura, Stewart Island where manifested passenger numbers across the Foveaux Strait are known. We have built a population model to ground truth such novel indicators. In our preliminary study, we find that a number of</div><div>indicators offer the opportunity to understand fluctuations in populations. Some indicators (such as wastewater volumes) can suggest relative changes in populations in a raw form. While other indicators (such as Tripadvisor reviews or Instagram posts) require further data enrichment to</div><div>get insights into population fluctuations. This research forms part of a larger research project looking to test and apply such novel indicators to inform disaster risk assessments.</div> 2019-12-01 23:00:45 Population movement tourism transient populations volunteered geographic information New Zealand Stewart Island Geospatial Information Systems
