The rapid development of global industrialization and urbanization has resulted in a great deal of electric power consumption (EPC), which is closely related to economic growth, carbon emissions, and the long-term stability of global climate. This study attempts to detect spatiotemporal dynamics of global EPC using the Defense Meteorological Satellite Program’s Operational Linescan System (DMSP-OLS)...
Depth is an essential characteristic of flood inundation in hydro-ecological research. Several studies have tried to estimate inundation depth from remotely sensed image and digital elevation model (DEM) data by applying a series of cross section profiles along the centerline of a river reach. This method requires a large amount of manual work in order to identify the centerlines and cross sections,...
In central and western regions where the topography is complex, various obstructions such as roads, rivers, and villages interfere the deployment of the mountain seismic line. In this paper, we compared the traditional operators, such as the Robert operator, the Sobel operator, and the Laplacian operator, discovering the defect in accuracy and noise resistance. Then, a computational approach using...
A new index mode for extraction of water body with HJ-1 satellite CCD imagery - Normalized Difference of RVI and NDWI(NDRW) which combined both RVI and NDWI values is purposed in this paper based on analyzing the spectral characteristics of water in HJ-1 satellite CCD imagery and the advantages and disadvantages of three the most frequently used indexes, which are Ratio Vegetation Index(RVI), Normalized...
With China's continuous economic development, the requirement of transportation capacity is increasing, and a corresponding increase in highway construction is raised to an important position. As regions, which highway route straddled, often have volatile features and complex geological environment. When facing the complicated geological environment, the traditional exploration methods in the field...
Ground subsidence in mining area does not only seriously damage land resource, surface engineering project, ground facilities and the surrounding environment, but also badly influence people's work and lives and greatly hinder the economic development in the mining area. In this paper, D-InSAR technology is used to research the land subsidence trend of Tangshan City from the year 1997 to 2004. Analyzing...
Mineral resource is the important material base for the humanity livelihood and development. But, it is unavoidable that development of mineral resources could cause a certain extent of destruction on ecological environment, In order to development mineral resources reasonably and prevent environmental problems effectively, carrying on the effective monitor to the environment's present situation and...
The Chinese HJ saterllite CCD sensor is similar to Landsat-5 TM with the same spatial resolution, but there are enormous advantages in space coverage and frequency of repeated observations. This paper focuses on the image quality evaluation of the four HJ CCD sensors by reference to Landsat TM data from near-synchronous images. The results are as follows: Mainly due to limited evel of radiation acceptance...
The remote sensing based Production Efficiency Models (PEMs), springs from the concept of “Light Use Efficiency” and has been applied more and more in estimating terrestrial Net Primary Productivity (NPP) regionally and globally. However, global NPP estimates vary greatly among different models in different data sources and handling methods. Because direct observation or measurement of NPP is unavailable...
It is discussed in this paper about how to use MSS, TM/ETM and CBERS-2 images to detect dynamically the ground sunk seeper in Kailuan Caol Mine, Which area ranging from E118deg20' ~~ 118deg34' to N39deg33'~~ 39deg46'. By extracting the 4 temporal RS images, the dynamic information on 28 years of ground sunk seeper in KaiLuan Coal Mine is achieved. The result shows that RS technology works very well...
An electronic nose-based network system is developed for monitoring odours around livestock farms remotely. This network is built from compact electronic noses which are tailored to detect odour compounds and environment conditions such as temperature, wind speed, and humidity. The electronic noses are placed at various locations of interest around the farm, and the collected odour data are dissemination...
