These data are publicly available upon request to the Australian Antarctic Data Centre. This collection of whale images have been converted to video format to reduce storage size and number of files, and to increase data integrity. The videos have been encoded using lossless ffv1 compression with 8-bit rgb pixels. Note that using lossless 8-bit rgb encoding means that it is unlikely that these videos will play correctly in conventional video viewing software (e.g. Windows Media Player or VLC). Hash information for the original files and individual frames within the videos are available in the hashes directory. To restore original (uncompressed) JPG images from the video files, use the open-source ffmpeg software (available in this directory or at http://ffmpeg.org - 12/09/2019) and see further instructions in the readme file in the "video images" folder in the dataset download. Note - each video file should be extracted to a separate folder.

Brief description

This dataset is a collection of aerial images taken from a camera mounted in the fuselage of the CASA-212 400 aircraft used to survey for pygmy blue whales. Line transect data from that survey are also available (but see Gill, P.C., Pirzl, R., Morrice, M.G. and Lawton, K. (2015). "Cetacean diversity of the continental shelf and slope off southern australia." The Journal of Wildlife Management 79(4): 672-681 for more details).

The digital images were taken with a Nikon D200 camera, using a 35mm lens. The survey altitude was approximately 1500 ft. Images have full EXIF data attached. Image footprints are approximately 204 m along-track by 306 m across track, with some image overlap.
