Trail Camera Images of New Zealand Animals

Overview

This data set contains approximately 2.5 million camera trap images from various projects across New Zealand. These projects were run by various organizations and took place in a diverse range of habitats using a variety of trail camera brands/models. Most images have been labeled by project staff and then verified by volunteers.

Labels are provided for 97 categories, primarily at the species level. For example, the most common labels are mouse (49% of images), possum (6.7%), and rat (5.5%). No empty images are provided, but some can be made available upon request. A full list of species and associated image counts is available here.

Downloading the data

Metadata is available at:

Images are available in the following Google Cloud Storage folder:

…and the following AWS S3 folder:

s3://us-west-2.opendata.source.coop/agentmorris/lila-wildlife/nz-trailcams

We recommend downloading images (the whole folder, or a subset of the folder) using gsutil (for GCP) or aws s3 (for AWS). For more information about using gsutil or aws s3, check out our guidelines for accessing images without using giant zipfiles.
