Research ArticleOpen accessIn the abstractLandscape Change and Sandy Desertification Monitoring and AssessmentEltahir Mohd Elhadi, Nagi Zomrawi, Hu GuangdaoProblem statement: The objective of this study is to develop techniques for assessing and analyzing sand desertification in the northern part of Shaanxi Province, China. Approach: In order to reveal the process of land degradation, especially the latest situation of sandy desertification, a method integrating remote sensing, Geographic Information System (GIS) and field survey was employed to build a sandy … …American Journal of Environmental Sciences, Vol. 5, Issue 5 · 31 Oct 2009 · 7,124 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeologic Mapping of United Arab Emirates using Multispectral Remotely Sensed DataMaged Marghany, Shattri Mansor, Mazlan HashimProblem statement: Geological studies are requiring standard methods and procedures to acquire precisely information. However, traditional methods might be difficult to use due to highly earth complex topography. Regarding the previous prospective, the advantage of satellite remote sensing in its application to geology is the wide coverage over the area of interest, where much accurate and useful information such as … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,582 accessesView PDFCite
Research ArticleOpen accessIn the abstractSoil Erosion Prediction Based on Land Use Changes (A Case in Neka Watershed)Karim Solaimani, Saeid Modallaldoust, Sedigheh LotfiProblem statement: Land use change has transformed a vast part of the natural landscapes of the developing world for the last 50 years. Land is a fundamental factor of production and though much of the course of human history, it has been tightly coupled with economic growth. Soil erosion by water is one of the most important land degradation processes … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 2 · 30 Jun 2009 · 8,447 accessesView PDFCite
Research ArticleOpen accessIn the abstractModels for Mixed Ensemble of Hydrometeors and their Use in Calculating the Total Random Cross Section of a Resolution Volume Filled by Random ScatterersAyman Al-Lawama, Salaheddin Malkawi, Abdullah Al-Odienat, Felix YanovskyFlight safety is of a major concern in aircrafts since the beginning of air traffic. One of the problems threatening the safety is the in-flight icing of the aircraft. This research deals with a problem arises in the context of weather aviation maintenance. Methods of aircraft icing are based on the difference in behavior of the polarization of radar signal … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 6,802 accessesView PDFCite
Research ArticleOpen accessIn the abstractSensitivity Analysis of an Optimal Access Road Location in HillyForest Area: A GIS ApproachMohd I. Hasmadi, J.C. TaylorThere are various models for establishing the efficient forest road allocation and evaluating optimum density of forest roads network for the transport of timber commodity. Most of them are based on the calculation of common timber transport costs and costs for forest roads. Today, forest road design from traditional method continues to be transformed by remote sensing technology and advancement … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,609 accessesView PDFCite
Research ArticleOpen accessIn the abstractExploring Spatial ARM (Spatial Association Rule Mining) for Geo-Decision Support SystemRanjana Vyas, Lokesh Kumar Sharma, U. S. TiwaryGeographical Decision Support System (Geo-DSS) is a demanding field, since enormous amount of spatial data have been collected in various applications, ranging form Remote Sensing to GIS, Computer Cartography, Environmental Assessment and Planning. Although some efforts were made to combine spatial mining with Spatial Decision Support System but mostly researchers for spatial database are using a popular data mining approach-Apriori … …Journal of Computer Science, Vol. 3, Issue 11 · 30 Nov 2007 · 6,956 accessesView PDFCite
Research ArticleOpen accessIn the abstractExploring Strategies for Parallel Computing of RS Data Assimilation with SWAP-GAShamim Akhter, Kiyoshi Honda, Yann Chemin, Putchong UthayopasAn agro-hydrological simulation model is useful for agriculture monitoring. One issue in running such model is parameter identification, especially when the target area is large such as provincial or country level. Remote Sensing (RS) provides us with useful information over large area. RS cannot observe input parameters of agro-hydrological models directly. However, a method to estimate input parameters of such … …Journal of Computer Science, Vol. 3, Issue 1 · 31 Jan 2007 · 7,209 accessesView PDFCite
Research ArticleOpen accessIn the abstractOOST: An Object Oriented Tool for Satellite Orbit DesignA. A. Salem, M. Zaki, A. A. WahdanIn this study the problems of satellite orbit design and simulation are tackled and an object oriented satellite tool OOST is developed. The tool with its three main modules enables the user to plan and design different satellite missions. It performs all orbital calculations needed, simulates the target orbit and performs analysis on the current active satellite(s). The simulation module … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 7,211 accessesView PDFCite
