Sand dredging has been practiced in rivers, lakes, harbours and coastal areas in recent years in China mostly because of demand from construction industry as building material. Sand dredging has distu...
Bush encroachment monitoring using multi-temporal Landsat data and random forests
Land degradation bush encroachment South Africa Landsat random forests classification
2014/11/28
It is widely accepted that land degradation and desertification (LDD) are serious global threats to humans and the environment. Around a third of savannahs in Africa are affected by LDD processes that...
NDVI from Landsat 8 Vegetation Indices to Study Movement Dynamics of Capra Ibex in Mountain Areas
Capra ibex Landsat 8 Vegetation indices Ethology modelling Pseudo invariant features

In this study we analyse the correlation between the spatial positions of Capra ibex (mountain goat) on an hourly basis and the information obtained from vegetation indices extracted from Landsat 8 da...
A new bare-soil index for rapid mapping developing areas using LANDSAT 8 data
Tasseled cap transformation Normalized difference bareness index Logical combination Landsat 8
2014/7/23
One of the most basic classification tasks is to distinguish bare-soil areas from urban region. Bare-soil plays an important role in the ecosystem. It could be the reason of dust storms and the indica...
