land evaluation is the process of predicting the land use potential on the basis of its attributes. at the present study the qualitative land suitability evaluation was investigated for specific cereal crops including irrigated wheat (triticum aestivum l.), mays (zea mays l.) and cotton (gossypium herbaceum l.), based on fao land evaluation frame works (1976, 1983 and1985), climatic and soil re...

A computer program, VVF, has been developed to assess the suitability of a territory as habitat for a species. It integrates several types of Habitat Suitability models into a Geographical Information System. In addition to standard GIS functions, VVF allows a user to create, modify and store new Habitat Suitability models for different species, to create Habitat Suitability maps by running Hab...

The increasing use and capability of geocomputation tools, as well as increasing availability of land resource information, offer opportunities to utilise such tools for the effective management of information for planning purposes. One among those is the development of spatially-based models that may be used for efficiently undertaking land suitability assessment based on available information...

This study aimed to analyse and evaluate the land suitability for certain fruit trees in Thuy Bang commune using GIS techniques in combination with a multi-criteria approach. At first, the databases for GIS analyses had to be developed. The data were obtained through scientific literature review, expert opinions, interviews, and professional officers. The suitability assessment in the studied a...

In recent years, methods of fuzzy reasoning have been successfully developed for land evaluation. The accuracy of such land evaluation depends on the quality of weighing land characteristics with respect to their effects on crop production. This paper presents a spatially-based model of land suitability analysis. The main purposes were to (1) establish land suitability indices for irrigated whe...

Determining the feasibility of a large-scale afforestation program is one approach being investigated by the Government of Canada to increase Canada's potential to sequester carbon from the atmosphere. Large-scale afforestation, however, requires knowledge of where it is suitable to establish and grow trees. Spatial models based on Boolean logic and/or statistical models within a geographic inf...
