1:1million topographic map series of the Australian Antarctic Territory produced in 2023

Twenty-three 1:1 million topographic maps covering the Australian Antarctic Territory were published by the Division of National Mapping. Four of these maps were updated in 1987. Three additional maps were published for the Australian Antarctic Division (AAD) by the Australian Surveying and Land Information Group (AUSLIG) in 1989. Two of these were updated by the AAD between 1998 and 1999. In 2023, twenty-two updated 1:1 million topographic maps were produced by the AAD, covering from 36°E to 160°E in East Antarctica. Attached is a list of all maps and their map catalogue numbers. High-resolution files from the SCAR Map Catalogue are available from the download links below. The A4 legend for the series is included in every SCAR Map Catalogue entry for the map series.The maps are available in the SCAR Map Catalogue:• SQ 37-38: Map Catalogue No. 16202 – https://data.aad.gov.au/map-catalogue/map/16202• SQ 39-40: Map Catalogue No. 16203 – https://data.aad.gov.au/map-catalogue/map/16203• SQ 41-42: Map Catalogue No. 16204 – https://data.aad.gov.au/map-catalogue/map/16204• SQ 43-44: Map Catalogue No. 16205 – https://data.aad.gov.au/map-catalogue/map/16205• SQ 45-46: Map Catalogue No. 16206 – https://data.aad.gov.au/map-catalogue/map/16206• SQ 47-48: Map Catalogue No. 16207 – https://data.aad.gov.au/map-catalogue/map/16207• SQ 49-50: Map Catalogue No. 16208 – https://data.aad.gov.au/map-catalogue/map/16208• SQ 51-52: Map Catalogue No. 16209 – https://data.aad.gov.au/map-catalogue/map/16209• SQ 53-54: Map Catalogue No. 16210 – https://data.aad.gov.au/map-catalogue/map/16210• SQ 55-56: Map Catalogue No. 16211 – https://data.aad.gov.au/map-catalogue/map/16211• SR 37-38: Map Catalogue No. 16212 – https://data.aad.gov.au/map-catalogue/map/16212• SR 39-40: Map Catalogue No. 16213 – https://data.aad.gov.au/map-catalogue/map/16213• SR 41-42: Map Catalogue No. 16214 – https://data.aad.gov.au/map-catalogue/map/16214• SR 43-44: Map Catalogue No. 16215 – https://data.aad.gov.au/map-catalogue/map/16215• SR 49-50: Map Catalogue No. 16216 – https://data.aad.gov.au/map-catalogue/map/16216• SR 55-56: Map Catalogue No. 16217 – https://data.aad.gov.au/map-catalogue/map/16217• SR 57-58: Map Catalogue No. 16218 – https://data.aad.gov.au/map-catalogue/map/16218• SS 40-42: Map Catalogue No. 16219 – https://data.aad.gov.au/map-catalogue/map/16219• SS 43-45: Map Catalogue No. 16220 – https://data.aad.gov.au/map-catalogue/map/16220• SS 55-57: Map Catalogue No. 16221 – https://data.aad.gov.au/map-catalogue/map/16221• ST 54-57: Map Catalogue No. 16222 – https://data.aad.gov.au/map-catalogue/map/16222• SU 53-57: Map Catalogue No. 16223 – https://data.aad.gov.au/map-catalogue/map/16223To view data sources and imagery used in the creation of this map series, see metadata record: https://data.aad.gov.au/metadata/East_Antarctic_25K_topographic_data_2023Note: Data delivered from the services linked to this metadata record may link to data more current than described in this record.

The LIMA mosaic is used with a 50% transparency over the Rema2 hillshade. This layer adds some depth, definition and colour and disguises some artifacts in Rema2 data. Note: Sentinel 2 Imagery were unavailable for a small portion of the final map in the series, SU 53-57.
