Based on the Landsat images in 2006, 2011 and 2015, and the method of dimidiate pixel model, the Normalized Difference Vegetation Index (NDVI) and the vegetation coverage, this paper analyzes the spat...
Indentifying the spatio-temporal patterns of ecosystem services supply and demand and the driving forces is of great significance to the regional ecological security and sustainable socio-economic dev...
The matrix of energy generation in Brazil is predominantly hydroelectric power. Consequently, the reservoirs need constant monitoring due to the large volume of artificially dammed water. Images from ...
The coal development zone of Northern Shaanxi, China is one of the eight largest coal mines in the world, also the national energy and chemical bases. However, the coal mining leads to ground surface ...
In recent decades, rapid rates of population growth and urban expansion affect local and regional ecosystems, climate, biogeochemistry, as well as food production. Ninety percent of urbanization will ...
The Lake Urmiah has undergone a drastic shrinkage in size over the past few decades. The initial intention of this paper is to present an approach for determining the so called salient times” during ...
In traditional approach, the land surface temperature (LST) is estimated by the permanent or portable ground-based weather stations. Due to the lack of adequate distribution of weather stations, a uni...
From the beginning of the 80’s, the PETROBRáS, Brazilian petroleum company, started the hydrocarbonets economic exploration in Urucu (AM), in the West Amazon region. This paper presents multitemporal...
This paper presents a new application of a data-clustering algorithm in Landsat image classification, which improves on conventional classification methods. Neural networks have been widely used in ...
Unpaved roads are one of the most relevant causes of erosion process in rural regions. Locating unpaved roads in low-resolution satellite images is not a trivial task. Although they have the spectra...
In order to utilize remote sensed images effectively, a lot of image classification methods are suggested for many years. But the accuracy of traditional methods based on pixel-based classification is...
Fractional tree cover (Fcover) is an important biophysical variable for measuring forest degradation and characterizing land cover. Recently, atmospherically corrected Landsat data have become avail...
This paper presents a methodological approach to combine land use information obtained from different processing methods. The first one is a traditional multispectral classification of multitemporal...
This is a pilot study of rangeland degradation in Xilin Gol Plateau of Inner Mongolia of the North China by using Landsat imagery. The plateau is relatively flat and temperate dry steppe is the main ...
Time sequential Landsat MSS and TM images were used to map land use/cover of the Atlanta metropolitan area for the past 25 years as a component of the NASA-funded Project ATLANTA (ATlanta Land-use AN...
