Antarctic topographic map of Lutzow-Holm Bay, 1:250,000

These data are schematized with map symbols and others based on vector data of topographic map. There are two types of data available: (data1: geometrically corrected data) and (data2: raw image data).本数据集以地形图（topographic map）矢量数据（vector data）为基础，通过地图符号及其他手段完成了符号化处理。当前可获取两类数据：（数据1：几何校正数据（geometrically corrected data））与（数据2：原始图像数据（raw image data））。
