This paper addresses the quantification of glacier retreat through remote sensing. Specifically, we use multi-spectral Landsat satellite images for the estimation of glacier termini locations. Different frequency bands—including visual, infrared, thermal, and processed bands—are examined with respect to their utility in identifying the location of glacier termini and the associated standard error across several scenes. The methodology is to extract an intensity profile along the glacier path from the spatially registered Landsat imagery such that the complexity of the problem is reduced from 2D (image intensity) to 1D (glacier profile intensity). Local polynomial regression is then used to smooth the 1D glacier intensity profile, where the underlying function is assumed to be corrupted with correlated noise. The glacier terminus is then detected by locating an inflection point in the smoothed glacier profile, where a constrained …
