Shirley Island Adelie Penguin Colonies, GIS layer
Entry ID: ASAC_1219_AAT_SI_ADPE_Colonies

Abstract: An ArcGIS shapefile layer showing the extent of all extant and relic Adelie penguin (Pygoscelis adeliae) colonies on Shirley Island, Windmill Islands, February 2006. The field Status describes each polygon as extant, relic or maximum. Extant refers to the area used by breeding birds in the summer 2005/06. Maximum refers to the historic maximal extent of the colony. Relic refers to any colony which ... View entire text

Quality This shapefile was created using a Trimble pro XH differential GPS.

Mean vertical precision = 1.34m, StDev = 0.46m Mean horizontal precision = 0.69m, StDev = 0.24m

Positional accuracy is approx. 1-2 m, after accounting for dGPS errors and errors in identification of the boundaries of colonies. Mapping was conducted after the end of the breeding season, so boundaries were identified as the extent of nest pebbles/fresh faeces, and it was considered that they could be reliably identified to within 0.5m.
