Antarctic Topographic Map 1:25,000, 201 Sinnan Iwa. Printed in Mar., 2010 (PDF Format)

Map compilation from aerial photographs of 1962 and from result of control point survey implemented by Japanese Antarctic Research Expeditions 1974-1976.The numbered grid lines are 1km intervals of the UTM-grid (Zone 37). Coordinates of the origin of projection (39E, 0S) correspond to 500kmE and 10,000kmN on this grid.本数据集基于1962年航空摄影资料与1974-1976年日本南极考察队实施的控制点测量成果开展地图编绘。带编号的网格线为通用横轴墨卡托格网（UTM-grid，Zone 37）下的1千米间隔格网。该投影原点的坐标（39°E，0°S）对应本格网中的500千米东向坐标与10000千米北向坐标。
