Data from: Snapshot Serengeti, high-frequency annotated camera trap images of 40 mammalian species in an African savanna

Gold Standard DataExpert classifications for 4,149 image sets. Unlike Snapshot Serengeti volunteers, experts were allowed to indicate if a capture event was impossible to identify. Fields are as follows: CaptureEventID: Same indicator as in the raw and reduced classification data; NumSpecies: The number of species in this capture event; Species: One of the 48 possibilities or “impossible"; Count: Number of individuals, estimated as 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11-50 or 51+.gold_standard_data.csvOperation DatesThe dates that each camera was active and functioning properly, extracted from the image EXIF data as the first and last dates of valid photographs on a given SD card. Valid photographs are defined as those taken while the camera was secured on the tree pointing outwards (in contrast to photos taken after a camera was torn down and facing the ground).search_effort.csvConsensus classifications and metadataWe applied the plurality algorithm (described in the manuscript) to the raw classification data to produce a single classification per capture event, accompanied by measures of uncertainty and difficulty. Each species classified in a single capture event receives its own record and species-specific measures of uncertainty. Metadata (data/time & location) are included to facilitate ecological analyses. This dataset excludes all images retired as “blank.”consensus_data.csvImagesURL information for retrieving each image; 1 record per image. All images in this data descriptor can be accessed at https://snapshotserengeti.s3.msi.umn.edu/ by appending the URL_Info field. For example, appending the value ‘S1/B04/B04_R1/S1_B04_R1_PICT0012.JPG’ yields the full URL: https://snapshotserengeti.s3.msi.umn.edu/S1/B04/B04_R1/S1_B04_R1_PICT0012.JPG. Pasting this value into a browser will display the image in the browser.all_images.csvRaw classification dataRaw classification dataset; 1 record per unique user, capture event, and species. Includes images retired as “Blank” and “Blank_consensus.”raw_data_for_dryad.csv.zip
