Introduction

Using land efficiently and in accordance with the site’s suitability for the intended purposes is a fundamental principle of sustainable development. Site suitability is a function of site conditions and other factors (environmental, socio-economic etc) . Carefully chosen selection criteria can efficiently screen the set of potential sites. Selection criteria focus on the task of choosing an appropriate and, ideally, the best site for a particular land use. This project deals with the use of Spatial Multiple Criteria Evaluation module in ILWIS software, as a decision support tool for identifying the suitable sites for landfill in the City of Ottawa.
