Heard and McDonald Island Management Maps 2022

The Heard Island and McDonald Island management maps and polygon datasets stored in a Quantum Geographical Information System (QGIS) GeoPackage format. The four maps were developed to update the management zones figures in accordance with the Heard Island and McDonald Island Marine Research Management Plan, 2014-2024. The unaltered datasets used included the ANARE historical Sites, countours_terrasar_100m_draft, flyingbird_pt_heard_pt_0304, sealer historical sites and WATERCOURSE_LN_heard. Several of the older datasets were updated or edited these include; the Antarctic prion nests and HI_South Georgian diving petrel 2003-4, which were adapted from the FLYING_BIRD_PY_heard dataset. The Current buildings on HI_2001 and HI_Refuge_operational datasets were adapted from the heard_infrastructure dataset. The ShagIsland_Sail_DruryRocks was adapted from the 2009 DEM. Alert Island dataset was digitised from a panchromatic Digital Globe Worldview-1 satellite imagery acquired on 23 March 2008.Additional datasets were created for this project including – HI glaciers 2014; HI_Coastline_2014; HI_Lagoons2014; and the HI_Vegetation Zone 2014; all of which were digitised from a pansharpened image derived from multispectral and panchromatic Digital Globe GeoEye-1 satellite imagery acquired on 6 February 2014. The HI glaciers 2014 dataset is an estimate of glacier coverage of the island in 2014 (some semi-permeant snow areas may be included, therefore should not be used to calculate total glacier area of the island). The HI_Vegetation Zone 2014 was created using the False Colour (FC) images created by Digital Globe from the pansharpened image derived from multispectral and panchromatic Digital Globe GeoEye-1 satellite imagery, which was used to estimate the vegetation coverage of the island. The vegetation zone dataset should not be used to calculate total vegetation coverage of the island.HI_LongBeach_Macaroni_Colony_2012-2016 was digitised from three pansharpened images derived from multispectral and panchromatic two GeoEye-1 satellite imageries acquired on 2 February 2012 and 6 February 2014 and Worldview-2 imagery acquired on 21 February 2016.The HI_Heritage_Zone_2021; HI_MainUseZone_2021; HI_RestrictedZone_2021; and HI-VisitorAccessZone_2021 were all digitised based on the areas as defined in the 2014-224 Management Plan and altered to fit the new 2014 coastline. HI_WildernessZone_2014 is a duplicate of the HI_Coastline_2014 with the symbology altered to reflect the Wilderness Zone as defined in the Management Plan 2014-2024. The McDonald Island coastline for 1980 (McD_1980_coastline) was digitised from the georeferenced 1980 aerial photo casa9491 image; the McD_2003_coastline was digitised from a pansharpened image derived from multispectral and panchromatic Digital Globe Quickbird satellite imagery acquired on 9 April 2003; the McD_coastline_2012 was digitised from a pansharpened image derived from multispectral and panchromatic Digital Globe GeoEye-1 satellite imagery acquired on 19 May 2012 and the McD_RestrictedZone_2022 was digitised from a pansharpened image derived from multispectral and panchromatic Maxar Worldview-3 satellite imagery acquired on 25 June 2020. As it encompasses the entire island it is also the 2020 coastline for McDonald Island.
