Bolingen Islands penguin GIS dataset
Entry ID:
bolingen_penguin_gis
Summary
Abstract:
Aerial photography (35mm film) of penguin colonies was acquired over the Bolingen Islands (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.

TOPIC:Planimetric accuracy of penguin colony transformations.
NOTE: The planimetric accuracy stated herein is relative to the existing GIS, coastline and penguin colony data - not 'absolute planimetric accuracy'. That is, it was assumed that the coastline and penguin colony data existing in the GIS is without error. Also, errors accumulated in the creation of the digitised penguin colonies (.DXF files) have not been considered here. The stated accuracy is an estimate - was not derived by statistical means. Whilst digitised colonies exist for Bolingen Islands: 1 and 2, transformations have not yet been performed due to inappropriate GIS base-data.
