Musk_Ox_census_area_Snow_cover

The snow cover is computed for the parts of the musk ox census area that is visible from the slope of Zackenberg where the automatic cameras are placed. Please find link to the shapefile for the region below.
Photos from three different camera positions are orthorectified and mosaicked together and the snow cover is computed based on these images. The dataset starts in 2008, but 2009 is missing, because there weren't enough cloudfree days during the snow melting period.
The images are captured every day at 13:20, which is solar noon in the Zackenberg valley.

本数据集针对自动相机布设的扎科恩贝格（Zackenberg）斜坡视野范围内的麝牛普查区域可见部分开展积雪覆盖范围计算。该区域的形状文件（shapefile）链接详见下文。来自三个不同拍摄点位的影像已完成正射校正（orthorectified）并拼接镶嵌，积雪覆盖范围即基于此类影像计算得出。本数据集的时间跨度始于2008年，但2009年的数据缺失，原因是融雪期内无足够多的无云天数。所有影像均于每日13:20拍摄，此时为扎科恩贝格河谷的太阳正午时刻。
