These images were collected to document and monitor effects of flooding, including property damage and erosion in Ellicott City, Maryland. A DJI Inspire 2 quadcopter with camera model FC6520 and a DJI Mavic Pro quadcopter with camera model FC220 were the UAS used to capture these images. Some photographs contain black and white targets used as ground control points (GCPs), which were surveyed by a field crew with a high-precision Real Time Kinematic Global Position System. This data release includes true color aerial imagery from the DJI Inspire 2 and DJI Mavic Pro quadcopters that are tagged with locations determined from the UAS GPS.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9XHZUW0", "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.5e0a7a21e4b0b207aa0d831f.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_5e0a7a21e4b0b207aa0d831f", "keyword": ["Ellicott City", "Historic Ellicott City", "Maryland", "Patapsco River", "USA", "USGS:5e0a7a21e4b0b207aa0d831f", "aerial images", "aerial photography", "airborne imagery", "dji inspire 2", "dji mavic pro", "drone", "geospatial datasets", "ground control point", "imageryBaseMapsEarthCover", "jpeg images", "low-altitude aerial imagery", "photographs", "photos", "targets", "u.s. geological survey", "uas", "unmanned aerial system", "usgs"], "modified": "2025-05-05T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-76.811300, 39.264066, -76.791048, 39.272239", "theme": ["geospatial"], "title": "Low-altitude aerial imagery from unmanned aerial systems (UAS) flight after the 2018 flood over historic Ellicott City, Maryland"}
