The appropriateness of a location to be selected as a seminar location is affected by many supporting factors, so that the location is suitable as a single choice. Hence, there should be made a process to decide a location whether it is proper or not to match some assessment criteria conceived before. There are 8 assessment criteria with 22 sub-criteria each. The result of the assessment forms ...

Ecosystem health is an important index of the regional sustainable development. In view of the singularity of indicator selection caused by the limited application of remote sensing and GIS at present, this paper took the Pressure-State-Response (PSR) model as reference, and revised the model in multi-analysis foundation. The pressure, vigor, organization structure, response and resilience were...

Environmental pollution of urban areas is one of key factors that state authorities and local agencies have to consider in the decisionmaking process. Understanding temporal and spatial distribution of air quality at the landscape scale is essential in assessing the potential ecological conditions for ecological restoration and in making decisions for regional management. To find a compromise a...

Vulnerability assessment is a significant component of effective disaster management. Following the Hyogo Framework for Action 2005-2015, countries need to identify appropriate vulnerability indicators and to assess the impact of disasters. Vulnerability assessment is a prerequisite for disaster risk reduction and capacity building of communities. It can play an important role especially for de...

Uncertainty analysis (UA) and Sensitivity analysis (SA) are prerequisites for model building. UA aims to quantify the overall uncertainty associated with the model response as a result of uncertainties in the model input. SA studies how the variation in the model output can be apportioned to different sources of variations. Both UA and SA have been successfully applied in many different fields....

In this study, a GIS-based tool has been developed to evaluate and predict coastal water quality issues for the Pearl River Estuary (PRE). The developed system consists of three key components. The first component is a database of hydrodynamic and water quality data collected from various public domains. This database is linked with the GIS for efficient retrieval, display, and analysis of hist...

Geographic information systems emerged in the 1970s and have become significant decisionmaking tools as their capabilities have been enhanced. This chapter includes a brief discussion of various GIS applications and a more detailed discussion of issues that public managers should consider when evaluating implementation of a geographic information system. GIS applications provide benefits at the...

Geographical Information Systems (GIS) are powerful tools in the field of invasive species management. GIS can be used to create potential distribution maps for all manner of taxa, including plants, animals, and diseases. GIS also performs well in the early detection and rapid assessment of invasive species. Here, we used GIS applications to investigate species richness and invasion patterns in...

Assessing urban vulnerability to natural hazards such as earthquakes can be regarded as an ill-structured problem (i.e. a problem for which there is no unique, identifiable, objectively optimal solution). A review of the literature indi­ cates a number of contrasting definitions of what vulnerability means, as well as numerous conflicting perspectives on what should or should not be included wi...

This paper describes a methodology for modelling light pollution using geographical information systems (GIS) and remote sensing (RS) technology. The proposed approach attempts to address the issue of environmental assessment in sensitive suburban areas. The modern way of life in developing countries is conductive to environmental degradation in urban and suburban areas. One specific parameter ...
