Aerial photography was acquired in January 2010 from a remote controlled helicopter at three locations - Antarctic Specially Protected Area (ASPA) 135, Robinson Ridge and near the Red Shed at Casey. In addition, highly accurate terrain data (points) was collected at each area using differential GPS. A detailed Digital Elevation Model (DEM) was generated for each area using the terrain data. The point data included the locations of small metal tags glued to rocks used for locating nearby quadrats. The quadrats have been used for long term monitoring of vegetation at ASPA 135 and Robinson Ridge. The quadrats were established in 2002/03 under AAS Project 1313 and have been monitored at approximately five yearly intervals under this project and the subsequent AAS Project 4036 (Chief Investigator: Professor Sharon Robinson, University of Wollongong). Near the Red Shed, an outline of the moss beds, streamlines and the general edge of the melt lake were captured using differential GPS. At Robinson Ridge, streamlines and the snowline were captured using differential GPS. The GPS data has an estimated horizontal accuracy of 2 cm. A georeferenced mosaic was created from the aerial photography for each area.
