This raster dataset describes elevation values, in meters (m), in Sleeping Bear Dunes National Lakeshore in 1955. The 1955 DEM was produced from historical aerial imagery acquired on April 1, 1955 at a flying height of 8,500 ft (1:17,000). Structure from motion (SfM) analysis of this imagery produced a 0.88 m DEM, which was edited and resampled to 1 m.
This raster dataset describes elevation values, in meters (m), in Sleeping Bear Dunes National Lakeshore in 1977. The 1977 DEM was produced from historical aerial imagery acquired on April 30, 1977 at a flying height of 8,500 ft (1:17,000). Structure from motion (SfM) analysis of this imagery produced a 0.89 m DEM, which was edited and resampled to 1 m.
This raster dataset describes terrain changes that occurred between 1955 and 2015 in Sleeping Bear Dunes National Lakeshore. The DoD values may be used to highlight landslide-prone areas and sand dune movements, as well as to identify other topographic changes caused by anthropogenic activities. The value of each 1 square meter gridcell in this raster indicates the elevation change that occurred in SBDNL between 1955 and 2015. The 1955 DEM was produced from historical aerial imagery acquired on April 1, 1955 at a flying height of 8,500 ft (1:17,000). Structure from motion (SfM) analysis of this imagery produced a 0.88 m DEM, which was edited and resampled to 1 m to match the 1m DEM produced from the 2015 lidar data....
