The satellite provides panchromatic imagery with 0.41 metre resolution and multispectral imagery with  1.65 metre resolution.\r\n\r\nThe panchromatic and multispectral bands were orthorectified using the RPC data files and the AADC's 5 metre resolution Digital Elevation Model of the island (see metadata record 'Macquarie Island AIRSAR DEM (Digital Elevation Model)', Entry ID: macca_dem_gis). The RPC orthorectification process works on a pixel-by-pixel basis to provide correct ground locations. The orthorectified image files are called GE_10Oct2011_pan_orc and GE_10Oct2011_ms_orc. These two images were then pansharpened using Gram-Schmidt spectral sharpening, the resulting image is called GE_10Oct2011_ps_orc.\r\n\r\nThe processing was done by Angela Bender of the AADC using IDL/ENVI version 4.8. The DEM was unprojected before the orthorectifications were done as ENVI version 4.8 requires a DEM, if used, to be unprojected.\r\n\r\nGround control points compiled by Angela Bender for the area covered by the image are provided (see a Related URL) but were not used in the orthorectification process. The ground control points were sourced from the AADC's survey control database and topographic data. The ground control points  could be used for future orthorectifications.\r\n\r\nThe pansharpened image could be coregistered with an orthorectified Quickbird  image captured 15 March 2005 (see metadata record 'Macquarie Island Quickbird Image (15 March 2005) orthorectification', Entry ID: Macquarie_Quickbird_15Mar2005) using 'image to image' transformation.\r\n\r\nIf this was done, the ground control points mentioned above could be used as a check of the coregistration. They could also be used to get an error estimate of the orthorectified Quickbird image.", "num_resources": 4, "num_tags": 12, "organization": {"id": "3e666ea1-f7c8-4382-a342-0e0bbc88ce9a", "name": "australianantarcticdivision", "title": "Australian Antarctic Division", "type": "organization", "description": "The Australian Antarctic Data Centre (AADC) was established in 1996 to provide long-term management of Australia's Antarctic data, thereby improving the value and impact of our scientific activities. The Data Centre is committed to the free and open exchange of scientific data, consistent with the Antarctic Treaty's position that \"to the greatest extent feasible and practicable scientific observations and results from Antarctica shall be exchanged and made freely available\".\r\n\r\nThe AADC team blends data management and scientific domain expertise with skills in computing, application development, geographic information systems, modelling, and statistical analyses. We work collaboratively with national and international centres, networks, and scientists, providing data management and analysis services as well as actively engaging in scientific research. As Australia's Antarctic Mapping agency, the AADC also supports the logistical operations of the Australian Antarctic Program.\r\n\r\nData held in the AADC are qualified with metadata and discoverable through the Catalogue of Australian Antarctic and Subantarctic Metadata (CAASM - http://data.aad.gov.au/aadc/metadata). Some data are also delivered through customised applications on the AADC website - http://data.aad.gov.au. Data delivery systems, where appropriate, use international standards for data exchange and data discovery.\r\n\r\nAADC staff assist in the capture of data at sea and on land, organise satellite tasking to support science campaigns, and provide advice on data collection methods.", "image_url": "http://data.aad.gov.au/static/images/aad_env_inline.png", "created": "2013-05-12T09:46:06.908895",
