SCANNING UNDERGROUND
• Project used digital imaging, terrestrial laser scanning, and aerial LiDAR combined with remote sensing and GPS survey
• We documented, prepared conditional analysis, and are developing public interpretation methods that extend management, preservation, and interpretation potentials that yield insight into important historical events in our Nation's history.
