Land suitability assessment is a prerequisite for sustainable forestry production. It involves simultaneous consideration of geo-morphological and ecological factors and environmental and socio-economic aspects in order to produce land potential maps for development of forestry production. These factors and remotely sensed data have been integrated through GIS modelling to define potential areas and identify better and more suitable places for predetermined forest trees. Three sets of Landsat ETM+ data acquired on 31 January and 24 April 2003 and 7 April 2004 were used in this research. An ISODATA unsupervised classification was performed based on fusion data from a composite image of the bands ETM3, ETM4 and ETM5 with panchromatic band.
