The Sydney Orthophotography 2011 is a series of digital imagery produced from aerial photography acquired over Sydney. The digital imagery was captured on the 15, 17 and 18 May, 20 and 25 June, 12 and 30 July and 17 September 2011. The tiles are 1 km X 1 km, with a 10 cm ground sample distance (GSD). Temporal information and geographic extents are stored in the individual metadata of each tile. Seam line information is stored in separate shape file which may be obtained upon request. Tiles are available in both ecw and tiff format. The expected reported accuracy for each tile is 0.2 m. Three mosaics were supplied by AAM for this project which covers Eastern Sydney, Western Sydney and Illawarra region. Mosaics are available in ecw format with targeted compression ratio 5:1. The mosaics are in Lamberts.
