Camera Trap Metadata Standard. Standards for camera-trap data captured in 35 fields at four hierarchical levels. All data fields are cross-referenced to common ecological metadata standards where possible. Projects may use either sections 3 (image sequence data) or 4 (image data) or both, depending how data is collected.
