World view2 satellite images for eastern coast of the Falkland Islands

The dataset comprises of 14 images for Berkeley Sound, 8 images for Adventure Sound and a further 3 for Choiseul taken at various months from 2011 to 2012. The images were used in addition to earth observation techniques to generate coastal habitat maps in the region of 200 metres from the shore.

Lineage Worldview2 provides a high resolution panchromatic band and eight multispectral bands. The purpose of acquiring the high resolution images was to perform a coastal habitat classification (terrestrial and marine) of the eastern coastline of the Falklands. The entire coastline was divided into three areas and images were acquired in different months: for Berkley sound on 11/11/2011 and 09/01/2012; for Adventure ssound on 27/9/2011; 22/10/2011; 09/01/2012; 24/07/2012; 06/10/2012; for Choiseul sound on 9/01/2012 and 24/7/2012. These acquisition dates were chosen with a view to using them for both a terrestrial and marine based classification. As a result of the duel-purpose nature of the imagery, the extent of cloud cover, any hillshade (from the sun angle at acquisition) and wave action became important factors in selecting the preferred dataset to work with. An image with no cloud cover but with high wave action could not be selected as the marine classification would be impeded. Similarly, an image captured on a calm day with no wave action but cloud over the land could also not be used as the terrestrial classification would be affected. There were a few areas were no perfect image could be sourced, and so a compromise was found. The satellite images were processed to account for satellite noise, the topography of the landscape and atmospheric interference. For the marine classification, further processing was required to reduce the effects of water surface reflection and the decay of light through the water column.
