Land evaluation is the assessment of land performance when used for specified purposes. As such it provide a rational basis for talking land use decision based on analysis of ralations between land use and land, giving estimates of required inputs and projected outputs (FAO, 1986).
The proper planning, design and management of land use demands a careful balancing of many goals, and the search for desirable land uses, coupled with effective and sustainable management practices, is made more complex by the interactions between the environment, the economy and society. One of the main reasons underlying the growing interest in multicriteria analysis for land use management is the need for an integrated approach to such complex problems. Multicriteria analysis can support the structuring of land use problems, allowing the concerns of major actors to be explored, giving trade-offs between conflicting goals, and leading to the evaluation of options from different perspectives. The integration of spatial concepts into multicriteria schemes means that this type of methodology can now make a substantial contribution to land-use management.
The primary issue in Multi-Criteria Evaluation is concerned with how to combine the information from several criteria to form a single index of evaluation. In the case of Boolean criteria (constraints), the solution usually lies in the union (logical OR) or intersection (logical AND) of conditions. However, for continuous factors, a weighted linear combination (Voogd, 1983) is usually used. With a weighted linear combination, factors are combined by applying a weight to each followed by a summation of the results to yield a suitability map
The sustainable development due to political decision is now a wording, which can be heard everywhere. There are typical components directly related to sustainable developments: They pro-ject into the future; there are sociological, economical and ecological criteria; and there are options, which are to be classified depending on their fullfillment of those criteria. A study on the method that will be developed for evaluation of the degree of suitability for physical and transportation distances (apart of infrastructure) evaluation in the Tan Phu Thanh village was done by using GIS technique in this paper .
