Around the 1960s, the group of Engineers and stakeholders came together to channelize the naturally flowing Kissimmee River basin to protect the river and its surrounding area from Flood events. However, consequences were not as it was imagined, the river basin lost most of its unique and native species of fishes, animals, birds, invertebrates, plants, and so on. By 1992, the state government again introduced a restoration program. This study to detect a change in vegetation, in the period of 11 years of the restoration project, made the use of NDVI technique. Band 3 and Band 4 Landsat 5-TM image of 1992 and 2003 were processed for NDVI calculation. NDVI thus obtained was reclassified into five major classes Water Bodies, Barren Land, Sparse Vegetation, Moderate Vegetation, and Dense Vegetation NDVI differencing was done to detect an increase and decrease in overall vegetation. Using similar classes Supervised Classification was also performed and Accuracy Assessment was done in order to verify the result with statistical support. Overall Accuracy and Kappa Coefficient was calculated for both before and after restoration program images and the values obtained were under the acceptable limit. The result from NDVI Differencing and Supervised Classification showed a positive impact of a restoration project on the ecosystem: The vegetation has increased significantly overtime of 11 years.
