Heard Island - GPS Seabird Survey 2000/2001

A GPS survey of seabirds on Heard Island during the Australian Antarctic Program's 2000/01 expedition.This layer is stored as two datasets (polygon and point) in the Geographical Information System (GIS).Polygon data represent flying bird and penguin colony extents.Point data represent nest locations and the location of the observation point for flying birds and penguins.本数据集源自澳大利亚南极项目（Australian Antarctic Program）2000/2001年度考察期间，在赫德岛（Heard Island）开展的海鸟GPS调查成果。该图层以多边形（polygon）与点（point）两类数据集的形式存储于地理信息系统（Geographical Information System, GIS）中。其中多边形数据集用于表征飞行鸟类与企鹅聚居地的分布范围；点数据集则用于记录鸟巢位置，以及飞行鸟类与企鹅的观测点坐标。
