GIS has been coming of age. Millions of people use one GIS or another every day,
and with the advent of Web 2.0 we are promised GIS functionality on virtually every
desktop and web-enabled cellphone. GIS knowledge, once restricted to a few insiders
working with minicomputers that, as a category, don’t exist any more, has
proliferated and is bestowed on students at just about every university and increasingly
in community colleges and secondary schools.
Using the analytic hierarchy process (AHP) method for multi-index evaluation has special
advantages, while the use of geographic information systems (GIS) is suitable for spatial
analysis. Combining AHP with GIS provides an effective approach for studies of mineral
potential mapping evaluation. Selection of potential areas for exploration is a complex
process in which many diverse criteria are to be considered.
In ARIES, Ecosystem Services are the effects on human well-being of the flow of benefits from an ecosystem endpoint to a human endpoint at given extents of space and time. The methodology combines spatially explicit models of ecosystem service provision and use with dynamic flow models to describe the distribution of benefits across the landscape. The exact form of these models depends on the specific context of application and is chosen by means of machine reasoning, on the basis of data analysis and ontological connotations of the services (e.g.
In recent years, under impacts of human activities and climate change, flood has been increased in both the frequency and magnitude, causing lots of damages to people. This study presents a method to evaluate the direct spatial damages of flooding based on inundation depth and land use data. Damage functions for different types of land use arc selected and applied. Matlab strings and GIS are combined to calculate damage in monitery term. The method is applied for estimating loss caused by thc flood event November 1999 for Huong rivce basin.
