Analysis Of Flickr, Snapchat, And Twitter Use For The Modeling Of Visitor Activity In Florida State Parks, Hartwig H. Hochmair, Levente Juhasz Sep 2019

Analysis Of Flickr, Snapchat, And Twitter Use For The Modeling Of Visitor Activity In Florida State Parks, Hartwig H. Hochmair, Levente Juhasz

Levente Juhasz

Spatio-temporal information attached to social media posts allows analysts to study human activity and travel behavior. This study analyzes contribution patterns to the Flickr, Snapchat, and Twitter platforms in over 100 state parks in Central and Northern Florida. The first part of the study correlates monthly visitor count data with the number of Flickr images, snaps, or tweets, contributed within the park areas. It provides insight into the suitability of these different social media platforms to be used as a proxy for the prediction of visitor numbers in state parks. The second part of the study analyzes the spatial distribution …

Comparing The Spatial And Temporal Activity Patterns Between Snapchat, Twitter And Flickr In Florida, Levente Juhasz, Hartwig H. Hochmair Sep 2019

Comparing The Spatial And Temporal Activity Patterns Between Snapchat, Twitter And Flickr In Florida, Levente Juhasz, Hartwig H. Hochmair

Levente Juhasz

Social media services generate enormous amounts of spatiotemporal data that can be used to characterize and analyse user activities and social behaviour. Although crowdsourced data have the advantage of comprehensive spatial and temporal coverage compared to data collected in more traditional ways, the various social media platforms target different user groups, which leads to user selection bias. Since data from social media platforms are used for a variety of geospatial applications, understanding such differences and their implications for analysis results is important for geoscientists. Therefore, this research analyses differences in spatial and temporal contribution patterns to three online platforms, namely …

Comparing The Characteristics Of Bicycle Trips Between Endomondo, Google Maps, And Mapquest, Angela Schirck-Matthews, Hartwig Hochmair, Dariia Strelnikova, Levente Juhasz Dec 2018

Comparing The Characteristics Of Bicycle Trips Between Endomondo, Google Maps, And Mapquest, Angela Schirck-Matthews, Hartwig Hochmair, Dariia Strelnikova, Levente Juhasz

Levente Juhasz

Numerous online trip planners, such as Google Maps and MapQuest, offer trip recommendations for cycling among other transportation modes. Whereas these platforms are widely used, little is known about the routing criteria embedded into their routing algorithms, and, more specifically, how recommended trips differ from routes travelled by cyclists. This study uses GPS tracking data from the Endomondo bicycle app to extract bicycle trips in Miami-Dade County, Florida. It compares Endomondo trip characteristics to the characteristics of bicycle trips obtained from Google Maps and MapQuest and the corresponding shortest path. Results highlight the attributes relating to road usage along a …


Analyzing The Spatial And Temporal Dynamics Of Snapchat, Levente Juhasz, Hartwig Hochmair Dec 2017

Analyzing The Spatial And Temporal Dynamics Of Snapchat, Levente Juhasz, Hartwig Hochmair

Levente Juhasz

Snapchat is a widely popular social-media platform among young people. In an update in February 2018, a web-based version of Snap Map was released. Besides using Snapchat for peer-to-peer chatting, users can submit photos and short videos to this feature. Snap Map was found to be useful for the dissemination of breaking news (e.g. protests) and the identification of local events (e.g. house fires) in quasi real-time. In order to understand the potential of the Snap Map feature for automated event extraction and answering societal questions, a better understanding of the characteristics of Snapchat data is necessary. Therefore, this paper …


Cross-Checking User Activities In Multiple Geo-Social Media Networks, Levente Juhasz, Hartwig Hochmair Dec 2017

Cross-Checking User Activities In Multiple Geo-Social Media Networks, Levente Juhasz, Hartwig Hochmair

Levente Juhasz

Geo-social media users tend to use different services simultaneously. Whereas significant research attention was put into analyzing contribution patterns to individual social-media platforms, it is less known how the same individual user uses different services. This pilot study analyzes the spatial behavior of users in multiple geo-social media services using geotagged Instagram media objects and Foursquare check-ins for 10 individual users. It assesses the usability of several methods a) to extract and map user activity spaces and b) to quantify the similarity of social media contributions of a user in different platforms. The analysis of user behavior across multiple platforms …
