This data release contains time-lapse imagery taken at U.S. Geological Survey (USGS) stream gaging stations with associated hydrologic and meteorological data related to each image. These data are to help improve the development of models in detecting water elevation at a given stream gaging station. Images of the water surface and surroundings at USGS stream gaging stations were taken at varying time intervals ranging between every five minutes to an hour. Cameras used include trail cameras, web cameras, and the custom river imagery sensing (RISE) camera. Time-lapse images for each USGS stream gaging station are provided in compressed files (file extension .7z). These files are named in a format to identify the USGS stream gaging station’s site number and station name. Hydrologic and meteorological data including stage, discharge, gage height, water surface elevation (or level), precipitation, relative humidity, water and/or air temperature, dew point, air pressure, and other weather condition information associated with each image are provided in comma-separated values files (file extension .csv). These files are named for users to easily relate the time-lapse images provided in the compressed files to the associated data using the same file naming convention. The hydrologic and meteorological data associated to each image is not the same and varies for each stream gaging station.
