Working on the 2020 update of the Sheltowee Trace maps using high-resolution DEMs derived from lidar point clouds. An elevation profile was created by sampling elevation every 264 feet along the 343-mile trail. This profile shows the proposed extension from Burnt Mill bridge to Rugby.

The resolution is high enough to see the indentation of wider trail beds, which helps verify GPS data.

The updated trail maps should be at the printer by mid-July.
