The application Geosites topoguide is a digital field guide to the geological treasures of Greece. All information has been collected, checked and edited by the R. Koutsi, PhD in hydrogeology.

The app contains 300 geosites, plotted on a very detailed and up-to-date map of Greece, offered by the cartographic group AnaDigit.

Geosites are categorized in the following 10 types:

• Tectonics
• Volcanos
• Karst formations
• Geoforms
• Paleontology
• Thermal springs
• Petrology
• Hydrology
• Museums
• Geoparks

Each geosite has a detailed description and photos. A navigation module offers routing information to the site, either by car or by hiking. Information and photos are updated regularly.
