Research ArticleOpen accessIn the abstractA Computational Optimized Extended Model for Mineral Potential Mapping Based on WofE MethodZiaii Mansour, Pouyan Ali, Ziaei MahdiThe multivariate fuzzy-c-means classifier is used to model extended weight of evidence (WofE) considering predictor maps. Approaches to mineral potential mapping based on WofE modeling generally use binary maps, whereas, real-world geospatial data are mostly multi-class or fuzzy-class in nature. The consequent reclassification of fuzzy-class maps into binary maps is a simplification that might result in a loss of information. … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,571 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSpatial-Temporal Yield Trend of Oil Palm as Influenced by Nitrogen Fertilizer ManagementAbdul Rahim Anuar, Kah Joh Goh, Tee Bee Heoh, Osumanu Haruna AhmedOne of the major challenges in oil palm (Elaeis guineensis Jacq.) plantations today is proper interpretation of yield maps for site-specific management and identification and understanding of the causal factors influencing the variability of oil palm yields. A study was conducted to examine the structural yield variation in order to assess the spatial and temporal yield trends so as to … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,550 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAn Integrated Approach to Modelling of Flood Hazards in the Rapidly Growing City of Osogbo, Osun State, NigeriaSuleiman Abdul-Azeez Adegboyega, Oluchi Christiana Onuoha, Komolafe Akinola Adesuji et al.In recent times, the swift and uncoordinated urban expansion in the medium sized city of Osogbo has increasingly encroached on the environmental sensitive areas. This uncoordinated exploitation of the ecological fragile areas for urban development has triggered urban flooding, which poses serious threat to human lives and properties in the city. This study therefore utilized geospatial technologies to generate flood … …Space Science International, Vol. 4, Issue 1 · 8 Jan 2018 · 13,835 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPotential Zones of Peruvanthanam and Valiyathodu Sub-Watersheds of Manimala River BasinVadakkepurakkal Rekha, Aikara Varkey George, Rita MendezGroundwater is a dynamic and replenishable natural resource. But in hard rock terrains, its availability is of limited extent. In sub-watershed studies, remote sensing and GIS techniques have the advantages of spatial, spectral and temporal data, covering large and inaccessible areas within a short span of time. Thus this technique has become a very handy tool in assessing and monitoring … …American Journal of Environmental Sciences, Vol. 9, Issue 1 · 20 Feb 2013 · 7,396 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIntegration of Electrical and Electromagnetic Investigation for Contaminated SiteAlberto Godio, Mario NaldiProblem statement: The environmental assessment of industrial areas is required to minimize the risk of soil and groundwater contamination. The survey of wide areas (e.g., some hectares) provides a high economical and complex logistical impact when random strategies of soil sampling are adopted. Recently, geophysical methods had been successfully adopted to drive the process of the spatial sampling of the … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 7,168 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordApplication of a Multi Stage Method to Assess the Landscape Alteration Induced by Quarrying Sites: A Comparative AnalysisDario Lippiello, Guido Alfaro Degan, Marco De Agostini, Mario PinzariThe aim of this study is to provide a design tool to forecast the effects that extraction methods and reclamation plans will generate on the land surrounding quarry sites. The method is based on a graphical approach and it consists of three consecutive phases. The first phase focuses on the quarry plant and aims to quantify the extent of the … …American Journal of Environmental Sciences, Vol. 12, Issue 5 · 2 Sep 2016 · 6,967 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordWeight of Evidence Allocates Mineral Depositional ZonesAbdullah A. Bokhari, Guang Dao HU, Rani FouadProblem statement: Yunnan province in general and Pulang area in particular is geological rich area which prevents field study in multi locations due to high risk outcrop. Approach: New technology such as Geographic Information System (GIS) and an ArcView extension module Arcweight of evidence (WofE) became very handy to provide safety for researchers and allow organization to control their budget. … …American Journal of Environmental Sciences, Vol. 6, Issue 6 · 31 Dec 2010 · 6,986 accessesView PDF Cite
