Extreme weather events, particularly the extraordinary rainfall in early 2020, resulted in mass movements and other hydrologic effects that substantially impacted the cultural and natural resources within the Vicksburg National Military Park (VICK), including the park's abundant cultural resources associated with the Civil War battlefield and a probable prehistoric cultural feature, as well as the infrastructure that provides public access to the park. Additional impacts occurred in perennial drainages and bayous due to increased sedimentation from landslide affected slopes, and to roads abutting the park boundary. Not only do these issues put facilities, cultural resources, and other infrastructure at risk of damage, they pose a serious risk to visitors and employees traveling within the park. An accurate and detailed basemap of the park’s topography is of crucial importance for mapping the extent of this landslide hazard and as a standard against which to measure future landslide activity. This dataset provides cutting-edge resolution from UAS-based lidar data as a means of accurately quantifying the 3D changes occurring in the park as a result of landslides. It is part of a larger project to provide park management with the current, accurate, and high-resolution geospatial data that enables both long-term planning and emergency response to VICK's landslide hazard.
