QUANTIFYING RATE OF VEGETATION COVER CHANGES IN ENUGU STATE USING NDVI TECHNIQUES FOR THE YEAR 1991, 2003 AND 2015

ABSTRACT

This project examines the rate of vegetation cover changes in Enugu State using NDVI techniques for the year 1991, 2003 and 2015 so as to detect changes that has taken place between these periods. The main goal of this study is to evaluate vegetation cover change of the study area using Normalized Vegetation Index (NDVI) in order to identify vegetation cover and the spatial distribution in the area for the period of investigation and to produce NDVI and spatio-temporal change maps as well as analyzing the spatio-temporal change of vegetation cover of Enugu State for the year 1991, 2003 2015. In achieving this, Landsat Satellite images of Enugu State were acquired for three epochs and the result shows that the forest cover is changing in the study area and NDVI classification maps for the epoch years reveal six category of vegetation covers via; No Vegetation, Less Vegetation, Less-Moderate Vegetation, Moderate Vegetation, Dense Vegetation and Highly Dense Vegetation.
