Abstract :
High resolution remote sensing satellite data serve as a source for equilibrium line (EL) analysis on top of glaciers. Data fusion techniques are used in order to take advantage from both the multispectral and panchromatic information available from simultaneously acquired IRS-LISS and -PAN recordings. As a result of segmentation between snow and ice the EL is derived based on multispectral classification of the fused data
