FLIPS (Flickr Images from Mountain National Parks) is a new dataset comprising photos showcasing human interactions with nature. This collection, sourced from the social media platform Flickr, includes images shared from 2015 to 2022 across eight mountain national parks: seven in Spain (Teide, Sierra Nevada, Sierra de las Nieves, Guadarrama, Picos de Europa, Ordesa y Monte Perdido, and Aigüestortes i Estany de Sant Maurici) and one in Portugal (Peneda-Gerês). The FLIPS dataset includes 960 images representing six CES (Cultural Ecosystem Services) categories: (1) Cultural-Religious. (2) Fauna-Flora. (3) Gastronomy. (4) Landscape-Nature. (5) Sport. (6) Urban-Rural. Each category is represented by 160 carefully curated images, reflecting diverse ways in which people engage with nature.
