Hillshade Rasters for Digital Elevation Models, 2002-2010, Version 1.0

Aerial stereophotography missions were flown at least once every year over the Columbia Glacier in 1976-2010, and documented further in the Aerial Inventory. Flight data include all existing scans of the large format diapositives and their derived data products from 2002-2010. This dataset includes hillshade rasters for all digital elevation models (DEMs) from 2002 through 2010. Data are in one TAR file.1976至2010年，研究团队每年至少对哥伦比亚冰川开展一次航空立体摄影测绘任务，相关测绘成果后续被收录于航空影像清单（Aerial Inventory）中。该航空测绘任务的飞行数据涵盖2002至2010年间所有现存的大幅面透明正片扫描文件，以及其衍生的数据产品。本数据集包含2002至2010年全部数字高程模型（DEMs）对应的晕渲栅格数据。所有数据均存储于单个TAR文件中。
