摘要

哨兵卫星星座系列由欧洲航天局开发和运营,代表了欧洲哥白尼计划的专用空间组成部分,致力于在环境、气候和安全方面的长期运营服务。获得的大量数据使我们能够进行不同的调查。我们决定检测朱利安阿尔卑斯山在不同季节的积雪变化。利用Sentinel-1在每个季节的图像计算了差异。提出的方法包括五个主要步骤,其中最重要的一步是差分SAR干涉测量(DInSAR)的计算。通过这样做,我们发现了雪的厚度在季节中是如何变化的。结果表明,该方法适用于雪位变化的检测。

Detection of snow levels in the Slovenian Alps at different seasons using Sentinel-1
The Sentinel satellite constellation series, developed and operated by the European Space Agency, represents a dedicated space component of the European Copernicus Programme, committed to long-term operational services in the environment, climate and security. A huge amount of obtained data allows us different surveys. We decided to detect changes in the snow cover in the Julian Alps at the different seasons. The differences have been calculated using Sentinel-1 images from each season period. The presented methodology consist of five main steps, where the most important step is the calculation of Differential SAR Interferometry (DInSAR). By doing this, we found out how the thickness of the snow changes during the seasons. As demonstrated by the results, the presented approach is suitable for detection of snow level changes.
