National Base Map - GreyScale MapServer

Brief description

This service is produced for the National Map project. It provides seamless topographic greyscale mapping for the whole of Australia, including the external territories of Cocos (Keeling) Islands, Christmas Island, Norfolk Island and Lord Howe Island. The service consists of Geoscience Australia data at smaller scales and OpenStreetMap data is used at larger scales. The service contains layer scale dependencies.

Lineage

Statement: The Australian Topographic greyscale map service is seamless national dataset coverage for the whole of Australia. The greyscale map base is derived from the colour map base with the exception of features such as Terrain, Hillshades, Reserves and Prohibited Areas. This map base also includes the external territories of Cocos (Keeling) Islands and Christmas Island. Norfolk Island and Lord Howe Island have been included also. These four islands use existing Geoscience Australia data and at larger scales OpenStreetMap data has been used. (These data for Christmas Island have been sourced from the Christmas Island Edition 1 NATMAP Topographic Mapping dataset (1:30,000 scale). These data for Cocos (Keeling) Islands have been sourced from the Cocos (Keeling) Islands Edition 1 NATMAP Topographic Mapping dataset (1:25,000 scale). The topographic information was checked in 2008 using satellite imagery, and supplemented using other sources in 2009. Limited field checking has been undertaken for these data and therefore some information may not be accurate. Information and assistance was supplied by the Attorney General's Department (Territories of Australia) and Department of Environment, Water, Heritage and the Arts (Parks Australia). Geoscience Australia gratefully acknowledges contributions to data content.) When viewing the map of mainland Australia beyond 1:100,000 scale, the data is derived from the Geoscience Australia GEODATA TOPO 250K product and in from 1:100,000 scale the data is derived from OpenStreetMap data ( © OpenStreetMap contributors). The suburbs layer is sourced from the Suburb 2011 data, Australian Bureau of Statistics. The map portrays detailed graphic representations of features that appear on the Earth's surface. These features include cultural, hydrography, marine, transport, vegetation and relief themes. The bathymetry image used for this map is sourced from Natural Earth.
