Full description

Aerial photography (Linhof) of penguin colonies was acquired over the Holme Bay (Eric Woehler).
The penguin colonies were traced, then digitised (John Cox), and saved as DXF-files.
Using the ArcView extension 'Register and Transform' (Tom Velthuis), The DXF-files were brought into a GIS and transformed to the appropriate islands. Data conforms to SCAR Feature Catalogue which can be searched (refer to link below).
