Topo 2.5M landmass mask of Australia

Abstract

The dataset was derived by the Bioregional Assessment Programme from Geoscience Australia GEODATA TOPO series - 1:1 Million to 1:10 Million scale data (GUID: 310c5d07-5a56-4cf7-a5c8-63bdb001cd1a). You can find a link to the parent datasets in the Lineage Field in this metadata statement. The History Field in this metadata statement describes how this dataset was derived.

This dataset contains a landmass mask of Australia.

Purpose

This mask has been developed to readily differentiate onshore and offshore areas thus allowing clear representation of data in the map by masking the offshore areas. It differs from the dataset Geoscience Australia Topographic 250K series 3 data (GUID: a0650f18-518a-4b99-a553-44f82f28bb5f) through the inclusion of the Gippsland Lakes.

This mask has been used in Gippsland Bioregional Assessment cartographic products to tidy overlapping layers or help display labels.

Dataset History

The 2.5 Million scale Mainlands and Islands layers from the Geoscience Australia GEODATA TOPO series - 1:1 Million to 1:10 Million scale data (GUID: 310c5d07-5a56-4cf7-a5c8-63bdb001cd1a) were clipped from a large rectangular extent layer of Australia within ESRI ArcMap 10.2. The mask area is essentially the non-land surface.
