Martinez, A., 2018, Time-lapse video of photographs of the Lake Sharpe Shoreline near Lower Brule, South Dakota, 2013–15: U.S. Geological Survey data release,


A sequence of images were captured automatically from trail cameras placed at three locations along the Lake Sharpe Shoreline near Lower Brule, South Dakota. The images were reviewed, and the best daylight image from each day was selected. The daily images were then displayed sequentially and recorded at 10 frames per second, creating a time-lapse video. The still images and videos in this dataset provide cues to what factors affected shoreline erosion in the camera field of view. This work was completed by the U.S. Geological Survey in cooperation with the Lower Brule Sioux Tribe Environmental Protection Office. The photos are available in jpg format and videos are provided in mp4 format. These are viewable with any compatible media [...]

The purpose of the time-lapse video is to allow visualization of the erosional processes that lead to shoreline collapse, and document the progression of erosion at the three sites equipped with cameras. This information can be used to help understand the conditions causing shoreline erosion, and may help inform decisions about erosion countermeasures that will protect land and water resources.
