What's there beyond the sun and the sea? Detecting tourists' interest towards nature in a mass tourism destination using social media data

People and Nature, EarlyView.
Abstract Nature‐based tourism is a rapidly growing subsector of the international tourism industry. However, capturing broad‐scale patterns of nature visits during touristic trips or visitors' appreciation of nature may be difficult using traditional data sources and methods. In this study, we harness geotagged social media data to understand the scale
