资源简介：
A digital elevation Model (DEM) of Macquarie Island with a five metre grid interval, and held in UTM Zone 57 , WGS 84 coordinates. Heights are referenced to mean sea level. 5 metre contours to the 5 metre level were derived.
This metadata record is related to the metadata record Macquarie Island and adjacent islands 1:50000 Coastline GIS Dataset.
The DEM was improved by Dr Michael Roach, Lecturer in Geophysics, School of Earth Sciences - CODES, University of Tasmania, Hobart, Tasmania, Australia and a copy provided to the Australian Antarctic Data Centre in January 2006. This improved version is the dataset available for download.
Details about the processing done by Dr Roach are available from the link below.
本数据集为麦夸里岛（Macquarie Island）的数字高程模型（Digital Elevation Model, DEM），网格间距为5米，采用WGS 84坐标系下的UTM 57区投影，高程基准为平均海平面。已生成5米等高距的等高线。
本元数据记录与《麦夸里岛及邻近岛屿1:50000比例尺海岸线GIS数据集》的元数据记录相关联。
该数字高程模型由澳大利亚塔斯马尼亚州霍巴特市塔斯马尼亚大学地球科学学院-CODES的地球物理学讲师迈克尔·罗奇（Michael Roach）博士改进，并于2006年1月向澳大利亚南极数据中心提供了副本。当前可供下载的即为该改进版本数据集。
