Heard Island - Ground Control Point Identification on 4 satellite images

Ground control points were captured in the field as described in the metadata record "Global change, biodiversity and conservation in terrestrial and coastal ecosystems on Heard and McDonald Islands [ASAC_1181]". The aim of this project was to identify the control points on various satellite images (Quickbird image captured 2003-Jan-17, IKONOS images captured 2004-Jan-25, 2005-Feb-7 and 2005-Feb-9) to determine image coordinates for the control points. These would then allow the satellite image to be adjusted to the ground control. There is a shapefile for each image with the features in the shapefile moved to the corresponding image location. Attributes in the shapefile include image coordinates (UTM43) and control point coordinates.
