Shared Aerial Drone Videos — Prospects and Problems for Volunteered Geographic Information Research

The practice of producing drone videos for hobby or commercial purposes has already created a vast amount of open and free video datasets. When these videos are properly authored, time-stamped and geo-referenced, they receive characteristics of volunteered geographic information (VGI). As alternative forms to user-generated content (UGC), these visually appealing footages attract significant attention, but their production faces different practical and motivational issues that could impose limitation on the value of this kind of VGI. In order to better understand volunteered geographic drone videos (VGDV) from the social media and VGI perspective we conceptualize and discuss prospects and problems that could be explored in further research. This paper contributes to the development of theory about aerial drone videos, exploration of aerial drone video UGC characteristics and to the applicability of drone videos in Digital Earth systems

Are Serbian tourists worried? The effect of psychological factors on tourists’ behavior based on the perceived risk

Recent natural hazards (floods and wildfires) which hit some of the most visited Greek tourist destinations during the summer season 2018 are threatening to decrease the number of tourist visits in the affected regions. As these regions, being namely Chalkidiki, Olympic Riviera and regions surrounding Athens and Thessaloniki, are the most popular summer destinations for Serbian tourists, it is interesting to examine how natural hazards that occurred there influence tourist behavior based on the perceived risk. The study aims to explore the role of psychological factors such as different personality traits and tourism worries on the tourist behavior based on the perceived risk of affected destinations. Moreover, the assumption was that tourism worrieswill mediate the relationship between analyzed personality traits and tourist behavior based on the perceived risk. Although previous studies investigated the effect of different psychological factors on tourist behavior based on the perceived risk, this is the first study to explore the interaction of different psychological factors including tourism worries, which previously were not analyzed in this context. Besides theoretical contribution, practical implications are also further discussed in the paper within the realm of their use for destination managers

Quantitative Geodiversity Assessment of the Fruška Gora Mt. (North Serbia) by Using the Geodiversity Index

The Fruška Gora Mt., as a dominant orographic complex in the Pannonian plain, was selected for a pioneer geodiversity quantification study area due to its unique geology and soil properties. The methodology is based on the geodiversity quantification assessment approach of Serrano and Ruiz-Flaño (Geogr Helv 62:140–147, 2007). It employed a 500 × 500 m grid approach on several maps (lithological, geomorphological, topographical, and pedological) at scales of 1:50.000 to 1:300.000, together with a 30-m resolution digital elevation model for deriving sub-indices and a topographic roughness. The geodiversity index values (Gd) indicate that the highest geodiversity sites are found on the north, north-east and south-western part of the investigated mountain: in steep-sided valleys, along the horst and loess cliffs facing the Danube River. The obtained results are compared with the already recognized in situ geosite location network. This approach can be applied in the given area for geoheritage protection, conservation, and promotion at different levels (from local to national level). Following the results of this study, the criteria for the definition of conservation areas with abiotic significance should be considered, as there is no legal protection of any kind for the areas with the highest geodiversity index values outside the National Park area. Also, it is a potentially effective tool for supporting decision-making processes regarding the management and conservation of natural areas or regions at different scales with further possible applications in Serbia and elsewhere in Europe
