Little Saint Francis River chat pile orthoimagery and elevation products, Missouri, July 2019.xml
Description
The products presented here document conditions at the Little Saint Francis River chat pile restoration site near Fredericktown, Missouri in July 2019. Imagery was collected shortly after the initiation of restoration actions. Images were collected using low-altitude flights of unoccupied aerial systems (UAS, or “drones”) and processed using structure-from-motion techniques to generate three dimensional products including the point cloud, digital elevation model, and orthoimage in this data set. The photographed area includes an area being restored to bottomland hardwood forest on the site of a remediated chat pile, as well as adjacent uplands. Images and derived elevation products provide baseline information about current terrestrial communities against which to compare changes following restoration of terrestrial areas.
