基于Landsat-8 OLI数据冰川信息提取与温度反演

Glacier Range Extraction and Temperature Inversion Based on Landsat-8 OLI Data

利用遥感技术可以测量的陆地冰川属性包括空间范围、表面地形、底部地形、总体积、表面流动场、积累和消融速度、表面分区、反照率等,以及这些量随着时间的变化情况。本文利用Landsat-8的影像数据,通过波段运算、监督与非监督分类等方法实现了冰川表面信息的提取,并反演得到了冰川的表面温度。

Remote sensing can be used to obtain the properties of land glacier that include the space range,surface topography,bottom topography,total volume,surface flow field,the rate of accumulation and ablation,partitioning of surface,albedo,etc.Furthermore,it’s change of this variable with time.This paper uses the image data from latest satellite Landsat-8 in the series of Landsat,by band operation,supervised and unsupervised classification,decision tree etc.to complete the extraction of glacier surface information,and get the glacier surface temperature by inversion.
