冰川边界上不同程度的碎片覆盖可能严重阻碍世界各地冰川的自动测绘和编目工作。出现这个问题是因为冰川上的碎片（即冰川上的碎片）和相邻的冰周碎片（发生在冰川边界之外）在太阳反射区域具有相似的光谱响应，因为两者来自同一来源（即山谷岩石）。本研究基于喜马拉雅山脉Chenab盆地一个试验区的遥感数据，表明热红外波段具有解决这种模糊性的潜力，因为发现冰上碎屑和冰周围碎屑之间存在相当大的温差。
The varying extent of debris cover on a glacier's boundary may seriously hinder automated mapping and inventorying of glaciers in various parts of the world. The problem arises because supraglacial debris (i.e. debris on the glacier) and the adjacent periglacial debris (occurring outside the glacier boundary) have a similar spectral response in the solar reflection region, as both are derived from the same source (i.e. the valley rock). This study based on remote sensing data in a test area in the Chenab basin, Himalayas, shows that the thermal infrared bands have potential in resolving such ambiguity, as considerable temperature differences are found to exist between supraglacial debris and periglacial debris.
