THE IMPACT OF ROCKY TOPOGRAPHY ON SHRUBLAND HERBACEOUS PRODUCTI VITY IN SEMI-ARID ENVIRONMENTS
Geography, Environment, Sustainability, 2015 One of the consequences of soil erosion in arid and semi-arid environments is the emergence of rocky shrublands. While their existence is well documented, gaps exist in our understanding of processes affecting the soil fertility inside them and in their ...

Despeckling SAR Image Quality Evaluation by Homogeneity and Heterogeneity Scene Patches
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingSynthetic aperture radar (SAR) imaging is hindered by coherent imaging mechanisms, leading to degradation in image quality due to speckle. Current methods can effectively suppress speckles but may lead to varying degrees of edge information loss.
