Gramvousa topoguide is a digital field guide for hikers and nature lovers visiting Crete. It includes routes, descriptions and photos for 12 hiking and mountaineering trails along the Kissamos, Falasarna, Gramvousa and Balos areas.
The application offers detailed offline maps and an extensive introduction on geography, geology, the nature and the rich ancient history of Kissamos, Falasarna, Gramvousa and Balos, including a comprehensive presentation of the nature of Western Crete (fauna and flora).
The app offers also a useful list of POIs with a comprehensive search engine.
The trails list includes easy and moderate hiking trails and long mountain traverses, of a total length of 60 km.
In the field, the application identifies the nearest route and make active navigation to it and then along it, with continuous messages to the user, while pops-up photos on every interesting or important terrain feature close to his position. If the hiker position is more than 20 meters far from the trail, the application warns him and suggests how to go back.

Olympus, Zagori, Sifnos, Naxos and other Aegean islands). To build the application and ensuring data accuracy, all paths of Gramvousa area have been revised during early 2018.
