Beschreibung:

This is a map of North Island in the Houtman Abrolhos off the coast of Western Australia. A small rock of the west coast of North Island, informally known as "Shag Rock", is also shown.

Areas shown in yellow are sparsely vegetated or unvegetated. Areas in green have reasonably dense vegetation.

Spatial information was traced from 1 metre resolution satellite imagery obtained using Google Earth, and can be assumed to be quite accurate. The huts in the southeast corner were also traced from satellite imagery, but identification of individual huts was problematic, and therefore probably inaccurate; these features should therefore be treated as indicative only of the spread and density of settlement.

Elevation features were not evident in satellite imagery so these have been placed in approximate position according to their position in a variety of sources, including the Gazetteer of Australia, the map Australia 1:100000 Topographic Survey Sheet 1641 (Edition 1): Wallabi, the digital topographic data (Version 2) of the Shuttle Radar Topography Mission (SRTM), and various other published maps, such as that on page 59 of Storr, G. M. (1960) "The physiography, vegetation and vertebrate Fauna of North Island", Journal of the Royal Society of Western Australia 43: 59–62.

Place names include both gazetted names, and informal names as used in publications such as Storr (1960) and Harvey, J. M., Alford, J. J., Longman, V. M. and Keighery, G. J. (2001) "A flora and vegetation survey of the Houtman Abrolhos, Western Australia", CALMScience 3(4):521–623.

Scale is accurate to about a metre per kilometre.
