Estimation of the Normalized Difference Vegetation Index (NDVI) Variation for Selected Regions in Iraq for two Years 1990 & 2001

The normalized difference vegetation index (ndvi) is commonly used as a measure of land surface greenness based on the assumption that ndvi value is positively proportional to the amount of green vegetation in an image pixel area. the normalized difference vegetation index data set of landsat based on the remote sensing information is used to estimate the area of plant cover in region west of baghdad during 1990-2001. the results show that in the period of 1990 and 2001 the plant area in region of baghdad increased from (44760.25) hectare to (75410.67) hectare. the vegetation area increased during the period 1990-2001, and decreases the exposed area.
