A user can register/authenticate (even with third-party authentication e.g. Google and Facebook). This functionality was realized using Keycloak (Open Source Identity and Access Management).
-
An authenticated user can view all trails uploaded to the system.
-
An authenticated user can enter new trails into the platform. A trail is characterized by a name, a duration, a level of difficulty, a starting point, a description (optional), and a geographic trail (optional) that represents it on a map. The geographic trail must be either manually entered (by interacting with an interactive map) or via file in standard GPX format.
-
It is possible to display a detail screen for each trail. This screen shows all known information about the trail and displays its route on an interactive map. In addition, the detail screen shows user reviews and uploaded photos. The user can also show their location (if the mobile device supports GPS location) on the map.
-
A user can download the trail in GPX format, or the summary information in PDF format.
-
A user can add or remove trails from their list of favorites.
-
A user can upload photos of a trail. If the photo has a geographic location saved in the metadata, a marker corresponding to the photo can be displayed on the map to show where it was taken on the trail. All photographs, before being uploaded, are examined to verify the presence or absence of illegal content (this feature was created using the AWS Rekognition cloud service).
-
A user can add a review to a trail.
-
A user can chat with another user to ask for more information on an itinerary he has entered.
