A spatial decision support system is a solution for spatial issues and problems applying a computer system and providing results for decision making. This comprehensive review study has been carried out to determine GIS and RS in SDSS towards water quality modeling in Malacca River. Rapid development in land use for human activities include agricultural and livestock activities, industrial acti...

Soil erosion is one of the most serious environmental problems affecting the quality of soil, land, and water resources upon which humans depend for their sustenance. A soil erosion hazard map is highly useful for environmental planning, soil conservation and management in soil erosion prone areas. In order to assess the soil erosion hazard, remote sensing (RS) and geographical information syst...

Remote Sensing as a direct adjunct to field, recently playing an important role in the study and assess the natural resource in any part of the world. Anthropogenic changes in land use and land cover and land use are often assumed to be identical, they are rather quite different. Land cover may be defined as the biophysical earth surface, while land use is often shaped by human, socio-economic ...

This paper presents the spatial susceptibility risk mapping of tuberculosis (TB) using a geographical information system (GIS) index model and satellite remote sensing (RS) imagery. GIS RS-based approach is proposed as an alternative method in identifying potentially high-risk areas Klang, Selangor. The level for selected socio-spatial factors map was classified into five-scale from 1, which no...

This paper reports findings from an AHRC-funded project into the use of more than one language in research projects. Using 35 seminar presentations and 25 researcher profiles, we investigated how researchers from differing disciplines became aware of the possibilities, complexities, and emerging practices of researching where more than one language is used: for example, in initial research desi...

Variations of heavy metals concentrations (Pb, Zn, Ni and Cd) in suspended matter as well as the physical properties (temperature, salinity, dissolved oxygen and pH) at five coastal sites and one reference station (offshore) were measured on seasonal base of the year 2005. Seasonal variations of seawater temperature, salinity, pH and dissolved oxygen were significant different, meanwhile; spati...
