利用遥感技术监测部分被碎片覆盖的冰川的困难是一个众所周知的问题。使用可见光（维斯）和近红外波段并不总是能提供足够的信息，以便利用遥感数据探测冰川边缘。在这项研究中，冰川探测的热波段的价值进行了调查。在此特别提请注意利用Landsat-TM和Terra-Aster数据进行冰川监测的不同机会。显示和讨论了根据空间分辨率的相应数据的一致性和差异。所介绍的案例研究是在碎片覆盖的贝尔韦代雷冰川，GLIMS项目的测试地点之一进行的。
The difficulties in monitoring partly debris covered glaciers by the application of remote sensing techniques is a well known problem. The use of visible (VIS) and near infrared (NIR) bands does not always provide sufficient information to detect the glaciers margins with remote sensing data. In this study the value of the thermal band for glacier detection is investigated. Particular attention is hereby drawn to the different opportunities of glacier monitoring using Landsat-TM and Terra-Aster data. Accordance and discrepancies of the respective data depending on the spatial resolution are shown and discussed. The presented case study was investigated at the debris covered Belvedere glacier, one of the test sites of the GLIMS project.
