Human impacts drive a global topographic signature in tree cover.

Does Topographic Normalization of Landsat Images Improve Fractional Tree Cover Mapping in Tropical Mountains?

Fractional tree cover (Fcover) is an important biophysical variable for measuring forest degradation and characterizing land cover. Recently, atmospherically corrected Landsat data have become available, providing opportunities for high-resolution mapping of forest attributes at global-scale. However, topographic correction is a pre-processing step that remains to be addressed. While several me...

Spatio-temporal analysis of snow cover in Iran based on topographic characteristics

Land-use change outweighs projected effects of changing rainfall on tree cover in sub-Saharan Africa.

Global change will likely affect savanna and forest structure and distributions, with implications for diversity within both biomes. Few studies have examined the impacts of both expected precipitation and land use changes on vegetation structure in the future, despite their likely severity. Here, we modeled tree cover in sub-Saharan Africa, as a proxy for vegetation structure and land cover ch...

Investigating the Effect of Topographic factors on the distribution of oriental beech in Hyrcanian forest, Iran

Studying the present and future distribution status of important forest species is a prerequisite for the need of conservation programs in order to play their undeniable role in tackling global climate change, land use change and air pollution. The purpose of this study was to determine the distribution of oriental beech (Fagus orientalis Lipsky) in forests of northern Iran under the influence ...

Microclimate land surface temperatures across urban land use/ land cover forms

Urbanization brings biophysical changes in the composition of the landscape. Such change has an impact on the thermal environment locally. The urban mosaic of land use and land cover is thus characteristically composed of local climate zones. The spatial variation in the land surface temperature across specific zone is studied for Bhopal city. The objective of the study was to understand how th...
