An ArcGIS shapefile layer showing the extent of all extant Adelie penguin (Pygoscelis adeliae) colonies at Nelly Island, Windmill Islands, December, 1990.
The colony boundaries were digitised from Linhof aerial photographs (ANTC1219, run 53, frames 5-7) that were georeferenced to the Windmill Islands Topopoly GIS dataset.
Data quality cannot be accurately assessed. Errors in the georeferencing process could not be quantified, and there are positional discrepancies between overlapping aerial photographs are up to 2.4 m. Thus, absolute errors in the position of the colonies cannot be quantified, but the colony boundaries should be within ~0.5m of their location within the photographs.
The shapefile and the georeferenced aerial photographs are available for download from a Related URL.
This work was completed as part of ASAC project 1219 (ASAC_1219).
