Monitoring Vegetation Growth of Spectrally Landsat Satellite ImageryETM+ 7 & TM 5 for Western Region of Iraq by Using Remote SensingTechniques.

Abstract

Landsat-5 Thematic Mapper (TM) has been imaging the Earth since March 1984
and Landsat-7 Enhanced Thematic Mapper Plus (ETM+) was added to the series of
Landsat instruments in April 1999. In this paper the two sensors are used to
monitoring the agriculture condition and detection the changing in the area of plant
covers, the stability and calibration of the ETM+ has been monitored extensively
since launch although it is not monitored for many years, TM now has a similar
system in place to monitor stability and calibration. By referring to statistical values
for the classification process, the results indicated that the state of vegetation in 1990
was in the proportion of 42.8%, while this percentage rose to 52.5% for the same
study area in 2002.
