Cover Story: Tourism is one of the most economically important industries worldwide. It is, however, vulnerable to disaster events. Geotagged social media data, as one of the forms of volunteered geographic information (VGI), has been widely explored to support the prevention, preparation, and response phases of disaster management, while little effort has been put on the recovery phase. Our study develops a scientific workflow and methods to monitor and assess post-disaster tourism recovery using geotagged Flickr photos, which involve a viewshed-based data quality enhancement, a space-time bin-based quantitative photo analysis, and a crowdsourcing-based qualitative photo analysis.
