The accuracy of snow cover information extraction in remote-sensing images dependent on a variety of factors, especially in mountain area with complex terrain. This paper aims at analyzing the accurac...
SNOW COVER AREA CHANGING ANALYSIS OVER TIBETAN PLATEAU WITH MODIS AND ASTER DATA
Changing analysis Snow cover Mapping Tibetan Plateau MODIS ASTER
2016/1/3
The Tibetan Plateau is called "the third pole" of the Earth by its highest altitude. So it is the most sensitive area in the world to hydrological cycle and climatic change. Estimating and mapping the...
Comparative Analysis of Hyperspectral and Multispectral Data for Mapping Snow Cover and Snow Grain Size
Hyperion ASTER Landsat Snow grain size
2014/12/15
The present study demonstrates the potential of imaging spectroscopy to produce the snow cover maps and estimation of snow grain size in the Himalayan region. Snow cover maps and snow grain size produ...
Enhancement of snow cover change detection with sparse representation and dictionary learning
Snow Cover Change Detection NDSI Sparse Representation K-SVD k-means clustering
2014/12/15
Sparse representation and decoding is often used for denoising images and compression of images with respect to inherent features. In this paper, we adopt a methodology incorporating sparse representa...
