ArcGIS Experience Builder

Explore the outdoors with the Elevation Profile widget

Whether I’m looking for the next peak to conquer or a scenic route to wander, I like to explore and fully evaluate my options. As a hiker, a climber, a biker, or even a paraglider, understanding the lay of the land before getting out there is key to being prepared.

With the Elevation Profile widget in ArcGIS Experience Builder, you can assess the intensity and technicality of a route by examining the elevation changes and choose suitable paths based on the desired challenge.

In the Rocky Mountain National Park Trails Viewer application below, selected trails from the list or on the map can be visualized with their elevation profile and statistics.
