This dataset is available in both GeoTIFF and MrSID formats. The GeoTIFF image should be used when fidelity, spatial accuracy, and radiometric integrity are critical for analysis or decision-making. The MrSID image, while optimized for efficient display and reduced file size, may introduce compression artifacts and should be used primarily for visualization or applications where performance is prioritized over analytical precision.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P137WWIS", "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.67d87e92d34e7c418d07a741.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_67d87e92d34e7c418d07a741", "keyword": ["Arizona", "California", "Colorado River", "Imperial", "La Paz", "Lower Colorado", "Riverside", "USGS:67d87e92d34e7c418d07a741", "aerial photography", "data management", "geoscientificInformation", "geospatial datasets", "image collections", "image mosaics", "imageryBaseMapsEarthCover", "inlandWaters"], "modified": "2025-09-15T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-114.7683, 33.1778, -114.4420, 33.7714", "theme": ["geospatial"], "title": "Georectified mosaic of historical aerial photographs of the Colorado River in Palo Verde Valley, Arizona and California, acquired in 1930"}
