Macquarie Island - Digitising topographic features

The topographical features were digitised from the Macquarie Island Quickbird orthorectifed satellite imagery (5 March 2005) with metadata record:

Entry ID: macquarie_quickbird_5March2005_mapping

The features were digitised at a scale of 1:2500 between April and August 2012.

All lakes that could be identified were digitised but many creeks, ridges and parts of the escarpment remain to be mapped.

It was difficult to determine where creeks became dry gullies and dry gullies became creeks so identification is not absolute.

Waterbodies (lakes and lagoons)  between the west coast and the base of the escarpment have been attributed as lakes but some or all may only be lagoons or wide shallow creeks - from the imagery it is difficult to determine the type of waterbody they are.

Only the major escarpment and ridges have been digitised.

Orthorectification of GeoEye-1 satellite imagery of northern Macquarie Island, captured 10 October 2011

The Australian Antarctic Data Centre (AADC) has GeoEye-1 satellite imagery of northern Macquarie Island, captured 10 October 2011. The satellite provides panchromatic imagery with 0.41 metre resolution and multispectral imagery with  1.65 metre resolution.

The 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.

The 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.

Ground 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.

The 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.

If 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.

Macquarie Island Helicopter Exclusion Zone

The Macquarie Island Helicopter Exclusion Zone was created in January 2005 in consultation with Peter Cusick, Parks and Wildlife Service, Tasmania.  The zone was created by buffering the coastline by 1 km on the seaward side of the island, generally following the escarpment on the interior of the island and buffering the refuges by 200 m to create an approximately 400 m wide  corridor to the refuges. Access corridors were also created at the station.  The Australian Antarctic Data Centre's topographic data representing  coastline, escarpment and refuges was used. In March 2007 the zone was modifed in consultation with Terry Reid, Parks and Wildlife Service, Tasmania. The corridors to the refuges were extended through to the escarpment.  The Helicopter Exclusion Zone is shown in a map of the island (see link below).

Geology of the Larsemann Hills 2004

The Larsemann Hills region is dominated by two major lithological associations, a Palaeoproterozoic felsic/mafic orthogneiss complex (S&oslash;strene Orthogneiss) which occurs as basement to a sequence of pelitic, psammitic and felsic paragneiss (supergroup = Brattstrand Paragneiss) and felsic intrusives. The depositional age of the Brattstrand Paragneiss sequences are controversial but isotopic data suggest derivation from the basement S&oslash;strene Orthogneiss. Current geochronology indicates that the region experienced medium to low pressure granulite-facies metamorphism during the Early Palaeozoic (~500 Ma). Although the paragneiss sequences record no evidence of earlier metamorphism, relicts of a previous metamorphic event at ~1000 Ma are preserved in the S&oslash;strene Orthogneiss. Within the Larsemann Hills region, the Early Palaeozoic event is characterised by peak metamorphism of ~7 kbar at ~800-850 degrees C, with the post-peak evolution characterised by decompression, with some cooling, to 4 kbars at 750 degrees C, then to 2-3 kbar at 600-650 degrees C during final stages of orogenesis, with exhumation largely driven by crustal extension. Tectonic models generally argue for a continental-continental collisional scenario, with thermal input derived from a thinned mantle lithosphere.

Margin of the Antarctic ice cover derived from Synthetic Aperture Radar images for the sector 79E-108E

Geographic location of the outer margin of the Antarctic ice cover for the sector between longitudes 79E and 108E, including margins of ice shelves, glaciers, and iceberg tongues.  The data set does not in general include the grounding zone at the inland margin of the ice shelves or glaciers.

The margin was defined by interpretation of an image mosaic generated from Synthetic Aperture Radar data.  The image mosaic was built using navigation data accompanying the SAR images to transform the images to a map projection. The image navigation data were adjusted so that overlapping images were registered to one another, the indivual images merged into a mosaic, and the overall process adjusted so that the mosaic was tied to the few ground control points available in this large sector.  Two separate mosaics were used to span the whole sector.

The majority of the SAR data were acquired by the ERS-SAR instruments in August 1996, some ERS data were acquired in August 1993, and one Radarsat scene was acquired in September 1997.  The data were pre-processed to produce a mosaic with a 100 m pixel size, and adjusted so that the majority of the coastline positions refer to the August 1996 epoch.

The location data are internally consistent, and extracted at nominally 200 m intervals.  The external position accuracy is generally better than 600 m. The coverage is complete over the whole sector.  The coordinate set includes some island/ice rise features.  Two very large grounded icebergs are included.

Data are in an ascii arc/info export file format as geographic coordinates on the ITRF1996 system and contains attribute information.

Heard Island: Baseline Data for Monitoring Longterm Change. (a) Vegetation Mapping from Orthophotos.

Vegetation mapping from orthophotos derived from non-metric photography for the north eastern, south eastern, south, west and north west coastal areas of Heard Island.

More information about the vegetation mapping process is documented in a pdf report entitled 'Notes for Heard Island Vegetation Mapping project 2002-2006' available for download at the provided URL. The report is an updated version of the December 2004 pdf report entitled 'Heard Island Vegetation Mapping Report'.

The vegetation mapping project was undertaken between 1986 and 1988 (field mapping), 2002 and 2005 (digitising) and 2003-2004 (limited field checking).  The data for the mapping done on orthophotos are contained in two shapefiles as follows:

- Vegetation mapping polygons.

- Reliability (comments on quality of orthophoto coverage, areas of overlapping cover, etc).

Associated shapefiles are as follows:

- Aerial photo coverage, showing polygons for the areas where each orthophoto was used for mapping (see metadata record with ID HI_VEG_ORTHOPHOTOS_VEGMAP).

- Photo locations of 35mm photos used during mapping (see metadata record with ID HI_VEG_PHOTOS_VEGMAP).

Heard Island: baseline data for monitoring longterm change. (c) Orthophotos used for vegetation mapping.

The vegetation mapping project used a set of 1987 and 1980 orthophotos and orthophoto mosaics for mapping and screen-digitising (see "Quality" section).  Contact AADC for access to these. A shapefile of orthophoto coverage shows polygons for the areas where each orthophoto was used for mapping.  This is an essential guide for use when matching the vegetation polygons to the correct orthophotos.

A list of the orthophotos and orthophoto mosaics used for the vegetation mapping, with locations, is as follows:  ('orthoantc' signifies 1987 series, 'orthocasc' signifies 1980 series.  Run numbers are not included. Frame numbers are signified by 'f').
