Sentinel Trail
Utilities
Free
Sentinel is designed to help trail networks optimize the maintenance of their trails for mountain biking, hiking, nordic ski, and more.
Identify your trail building work with accuracy using your GPS position when patrolling the trails. Create as many tasks as you want for each problem identified, add photos to the description, and even add a list of materials needed to do the task.
Invite your team members to collaborate on the identification of the maintenance work.
Get an overview of all the tasks created by your team and prioritize the most critical maintenance work. Assign the tasks to your team members to make sure that they know what to focus on.
Cumulate data on the effort required to complete each task, the number of hours needed, and the materials and tools needed. Use this data to plan you maintenance for the next months and years and get a more precise budget.

- Snowmobile

Monitor your maintenance for multiple activities
When your trail network is dedicated to multiple activities like mountain biking, hiking, or even snowshoeing and nordic skiing, importing all the different trails on a single map becomes crowded and hard to visualize.
We’ve added the ability to segment your map by activity type, so that you can only see the trails meant for one activity at a time.
Customize the type of tasks you create
As of now, when creating new maintenance tasks on your trails, only preset types are available (fallen tree, broken plank, etc.), as well as an “Other” option.
However, when ending up with tons of “Other” tasks, it can be hard to have a good overview of the work you need to tackle on the field.
With custom types, you can create tasks that better reflect the type of maintenance work corresponding to your network and your needs. You have big machine-built projects under way? You could create “excavator” or “compactor” as custom types and select them in your new tasks.
1.4.6 07/28/2024
This new version brings two major updates: the ability to add time estimates to a task, and to access reports on the total hours completed on your tasks and on each trail.
