Virginia NRCS Conservation Innovation Grant 2020
Structure From Motion DEMs in the Smith Creek Watershed
This project is currently ongoing. WSI geoscience and GIS specialists have completed initial fieldwork and are currently processing drone photogrammetry for high-resolution DEM's of three sites on Virginia's Smith Creek.
WSI Specialists Logan Lewis and Sam Feibel stand in front of a well-preserved mill building at Sellers' Mill in Mauzy, VA. Logan and Sam used drone photogrammetry to create a digital elevation model of the eroding Legacy Sediment terraces upstream of the breached dam.

Rows of trees lining the old mill race are visible in this aerial drone shot of Sellers' Mill. The wide Legacy Sediment terraces formed behind a since-breached dam now serve as pasture for cattle.
