In July 2024 we replaced the BlazeVideo cameras with three Browning trail cameras. From July 2024 to November 2024 the Browning cameras took images every ten minutes. Browning cameras compile all images taken within a 24 hr period and generate time-lapse videos, which are included in this data release. The cameras are labeled GF31, GF32, and GF33. We kept the camera labels the same when we changed from BlazeVideo to Browning because the location of the cameras remained the same. The imagery component also includes camera metadata, such as the camera\u2019s height above the ground surface, the tilt angle relative to the horizontal (look angle), the compass direction the camera was facing (azimuth), and any adjustments made or observational notes.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P13HPPYM", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.678a94bed34e76fa5e3d6c8b.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_678a94bed34e76fa5e3d6c8b", "keyword": ["Arizona", "Dune field", "Grand Falls", "Navajo Indian Reservation", "USGS:678a94bed34e76fa5e3d6c8b", "atmospheric and climatic processes", "climatologyMeteorologyAtmosphere", "field inventory and monitoring", "field monitoring stations", "geoscientificInformation", "imageryBaseMapsEarthCover", "ripple migration", "time-sequence images"], "modified": "2026-04-09T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-111.18390, 35.42165, -111.14997, 35.44529", "theme": ["geospatial"], "title": "Images and time-lapse videos of a ripple field in Grand Falls Dune Field, Arizona, from July 2023 to November 2024, Grand Falls Dune Field, Arizona"}
