Ice Velocity Field for Lambert-Amery Glacial Basin Derived from 2000 Radarsat SAR Interferometric Data

Ice velocity field for the Lambert-Amery glacial basin, Antarctica are derived
based on three-pass Radarsat SAR interferometric data acquired in 2000. Two
grids are given in ArcInfo interchangable format. One shows the motion speed in
unit of meter per year, and the other shows the motion azimuthal direction in
degree. The spatial resolution is 400 m. The grids are in Polar Stereographic
projection with reference to WGS84 ellipsoid.

南极兰伯特-阿梅里冰盆（Lambert-Amery glacial basin）的冰流速度场，基于2000年获取的三程Radarsat合成孔径雷达（Synthetic Aperture Radar，SAR）干涉测量数据反演得到。数据集以ArcInfo交换格式（ArcInfo interchangeable format）提供了两个网格文件：其一存储了以米/年为单位的冰流速度，其二存储了以度为单位的冰流方位角。该数据集的空间分辨率为400米，所有网格采用以WGS84椭球体（WGS84 ellipsoid）为基准的极方位立体投影（Polar Stereographic projection）坐标系。
