5 CONCLUSION
This study has demonstrated the value of high resolution satellite imageries in vegetation mapping and
analysis, especially, in a developing country like Nigeria where aerial photographs are not available on a
regular basis. However, the precise classification of the vegetal types shown by the satellite imageries was
hampered by the heterogenous and unplanned nature of the landscape. Nevertheless, since this is explained
by confusion matrix, the accuracy of the map generated from the exercise could not be said to be in doubt
(Goodchild, 1987). It is necessary, in the light of the findings of this study, for the policy makers in the
country, to encourage the integration of remote sensing techniques, especially, the digital image analysis
into the regular resources surveys and inventory. This will constitute a major step toward the establishment
of a reliable data base on the biotic environment and capability building in forestry management in the
country.
