Nov 01, 2011· Using ERS1/2 Tandem and JERS-1 L band images captured between 1993 and 1995, combined with GIS, some quantitative analysis was made on land subsidence in Appin area caused by long wall coal mining . Hoffmann studied the land subsidence of Antelope valley in California caused by pumping the geothermal water to generate power [5] .

Mercury is a chemical element with the symbol Hg and atomic number 80. It is commonly known as quicksilver and was formerly named hydrargyrum (/ h aɪ ˈ d r ɑːr dʒ ər ə m / hy-DRAR-jər-əm). A heavy, silvery d-block element, mercury is the only metallic element that is liquid at standard conditions for temperature and pressure; the only other element that is liquid under these ...

The paper chooses Genhe, Inner Mongolia as the research area. Based on ArcGIS 9.2 and ENVI 4.8 software, the TM images of 2000、2004 and 2010, the decision tree classification was applied to interpret the images, and the land use data of 2000、2004 and 2010 were obtained. The land use transformation matrix and land use dynamic degree were analyzed further.

The defection of single data source can be solved with fusion between TM and SAR images. It provides a better solution for land surface monitoring in the mining areas. Results of experiment showed that the fusion images can be integrated the advantages of each one, enhanced the recognition ability of features, improved land use/land cover ...

Coal fires in the Jharia coalfield pose a serious threat to India's vital resource of primary coking coal and the regional environment. In order to undertake effective preventative measures, it is critical to detect the occurrence of subsurface coal fires and to monitor the extent of the existing ones. In this study, Differential Interferometric Synthetic Aperature Radar (DInSAR) technique ...

Jul 19, 2012· According to the FAO Global Forest Resource Assessment (FAO 2006a), forest is defined by the presence of trees with land covering more than 0.5 ha.The trees should be able to reach a minimum height of 5 m in situ and a canopy cover of at least 10%. For the purposes of national forest accounting and management, Indonesian forest is defined as an area with a minimum mapping unit of .

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Subsidence is the sudden sinking or gradual downward settling of the ground's surface with little or no horizontal motion. The definition of subsidence is not restricted by the rate, magnitude, or area involved in the downward movement. It may be caused by natural processes or by human activities.

NLCD (the National Land Cover Database) is a 30-m Landsat-based land cover database spanning 8 epochs (1992, 2001, 2004, 2006, 2008, 2011, 2013 and 2016). 1992 data are primarily based on unsupervised classification of Landsat data, while the rest of the images rely on the ...

The Moderate Resolution Imaging Spectroradiometer (MODIS) is known as an imaging device launched into globe orbit by means of NASA [].The devices capture records in 36 spectral bands varying in wavelength starting from 0.4×10 −6 m to 14.4 ×10 −6 m and at varying spatial motions. The Atmospheric Infrared Sounder, AIRS, is a service tool whose objective is to help climate study and develop ...

Feb 17, 2010· With the fast development of remote sensor technologies, e.g. the appearance of Very High Resolution (VHR) optical sensors, SAR, LiDAR, etc., mounted on either airborne or spaceborne platforms, multi-source remote sensing data fusion techniques are emerging due to the demand for new methods and algorithms. The general fusion techniques have been well developed and applied in .

High-intensity underground mining generates considerable surface subsidence in mining areas, including ground cracks and collapse pits on roads and farmland, threatening the safety of buildings. Large-amplitude subsidence (e.g., >2 m) is usually characterized by a large phase gradient in interferograms, leading to severe phase decorrelation and unwrapping errors.

The work focuses on time series analysis application through the high temporary resolution imagery from the SENTINEL 1A/1B mission. The analysis of surface subsidence in open pit mining area was performed by the selected InSAR approach - small baseline InSAR. This methodology allows for continuous monitoring of the mining area.
