A virtual 3D tour of the georeferenced sites was produced using augmented reality technique and geoinformatic tools which integrate thematic digital layers such as geological maps and orthophotos. Every stop in the tour includes descriptive and graphic elements that can be viewed in free virtual globes (e.g. Google Earth) combined with diagrams, photographs and information sheets that quantitatively assess the cultural-touristic, educational and scientific value of the geosites. A virtual flight itinerary compatible with video formats in the new freetechnologies (smartphones, tablets and iPads) is also presented.engjournal articlehttps://link.springer.com/search?query=Augmented+Reality+in+a+Hiking+Tour+of+the+Miocene+Geoheritage+of+the+Central+Algarve+Cliffs+%28Portugalrestricted access551.7Augmented realityGeological heritagePalaentologyGeomorphologyMiocene-AlgarveGeología estratigráfica2506.19 Estratigrafía
