    "descript": "In 2010, a video camera was installed near the northern boundary of the National Aeronautics and Space Administration-Kennedy Space Center (NASA-KSC) property along the Atlantic coast of Florida. A region extending 1 kilometer (km) to the south of the camera was established as the region of interest for the video image observations. During every daylight hour of camera operation from August 8, 2011 to July 24, 2012, a time exposure (timex) image product was created by averaging pixel color intensity for all frames collected during a 10-minute video at 2 frames per second (hertz, Hz). One timex image per day was used for analysis. The timex selected for each day was the product that was created when the tide level was closest to the Mean High Water (MHW) at the study site. Based on observed water levels from a nearby National Oceanic and Atmospheric Administration (NOAA) station, the MHW was determined to be 0.23 meters (m) above the North American Vertical Datum of 1988 (NAVD88) (NOAA, 2018). The shoreline was manually identified as the wet-dry line within the region of interest of each available timex product. Each day\u2019s MHW timex product was rectified to a horizontal map and converted to local and world coordinate systems, with the camera centered at the origin, using the established photogrammetric techniques outlined in Holland and others (1997). However, timex products were not available for about half of this timeframe due to camera malfunctions, adverse weather conditions (for example, fog), and\/or a lack of daylight during the timing of MHW. The average gap between observations is 2 days, with the largest gap being 12 days. Please carefully review the metadata for more information.",
