Hillshade Rasters for Digital Elevation Models, 2002-2010

<p> 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. </p> <p> This dataset includes hillshade rasters for all digital elevation models (DEMs) from 2002 through 2010. Data are in one TAR file. </p>

1976年至2010年间，研究团队每年至少对哥伦比亚冰川执行一次航空立体摄影航摄任务，相关成果于航空存档（Aerial Inventory）中得到进一步归档。航摄数据涵盖2002年至2010年间留存的所有大幅面透明正片扫描件及其衍生数据产品。
本数据集包含2002年至2010年间所有数字高程模型（Digital Elevation Model, DEM）对应的地形晕渲栅格数据，全部数据存储于单个TAR文件中。
