The wide application and rapid development of satellite remote sensing technology have put higher requirements on image segmentation methods. Because its characteristics large size, data volume, complex background, not only are the traditional methods difficult to apply effectively, but based deep learning faced with problem extremely unbalanced between categories. In order solve this problem, ...

The construction of Longyangxia Reservoir has altered the hydrogeological conditions its banks. Infiltration and erosion caused by periodic rise fall water level leads to collapse reservoir banks local deformation landslide. Due heterogeneous topographic characteristics across region, also varies between different location. Previous research on influence fluctuations in landslide focused single...

In the process of urbanization, various urban problems have become increasingly prominent, and heat island effect is one them. The expansion land, increase in construction intensity population make even worse. park cities improves ecological environment city considered to a positive on alleviating effect, but it not clear whether has such an or not. This article explores Park City can help impr...

As greenhouse gas emissions have been mounting in recent years, the issue of global warming has become more and serious, sparking a great deal concern. Among effects warming, melting snowpack is particularly pronounced. However, most current researches focus on vegetation biodiversity, there are some gaps studies snow mountainous regions China. This paper analyzes Landsat8 satellite images Chan...

Regarding the ever increasing and frequent occurrence of serious landslide disaster in eastern Guangxi, current study was implemented to adopt support vector machines (SVM), particle swarm optimization (PSO-SVM), random forest (RF), (PSO-RF) methods assess susceptibility Zhaoping County. To this end, 10 disaster-related variables including digital elevation model (DEM)-derived, meteorology-deri...

The evaluation of vegetation cover after post-fire treatments burned lands is important for forest managers to restore soil quality and plant biodiversity in ecosystems. Unfortunately, this may be time consuming expensive, requiring much fieldwork surveys. use remote sensing, which makes these activities quicker easier, have rarely been carried out the Mediterranean forests, subjected wildfire ...

Remote sensing techniques used in many studies for classfying and measuring of wildfires. Satellite Landsat8(OLI) imagery is the presented work. The satellite considered as a near-polar orbit, with high multispectral resolution covering Wollemi National Park Australia. work aims to study measure wildfire natural resources prior throughout fire breakout which occurred Australia year (October, 20...

The main aim of this study was to assess and mapping land cover (LC) / use (LU), using Remote Sensing (RS) Geographical Information System (GIS) techniques in Elnor natural forest reserve, Blue Nile state, Sudan. also attempted update some information the area such as LC contour map by different methods data transformation analysis Normalized Different Vegetation Index (NDVI), interpolation sup...
