Example Camera Trap Survey
Version: 1.0
A small, synthetic camera-trap dataset — 2 deployments, 5 media files (one private), 5 observations — used as a wildintel-publisher example. Not real field data; the images are generated placeholders, not photographs.
Dataset format
This dataset is distributed as a Camtrap DP data package — the community standard for structuring and sharing camera-trap data.
.
├── datapackage.json ← Camtrap DP metadata descriptor
├── deployments.csv ← camera deployment records
├── media.csv ← media (image) records — public media only, filePath is remote
├── observations.csv ← classification/observation records
├── images/ ← the public image files referenced in media.csv
├── camtrapdp-local.zip ← same package, but media.csv's filePath is relative to images/
├── checksums-sha256.txt
├── CITATION.cff
└── LICENSE
camtrapdp-local.zip is meant for local use: extract it next to the images/ folder and
media.csv's filePath will already point to images/<file> instead of a remote URL — no
network access needed to resolve media files.
Privacy
Only media marked as public (filePublic=true in media.csv) is included in this
export. Observations tied exclusively to non-public media have been removed.
Integrity verification
checksums-sha256.txt lists the SHA-256 hash of every file in this export, to verify
nothing was corrupted or truncated after downloading.
