MAPPING LAND USE/ LAND COVER OF WEST GODAVARI DISTRICT USING NDVI TECHNIQUES AND GIS

Civil Engineering

The present study shows that satellite remote sensing based land cover mapping is very effective. The high resolution satellite data such as LISS III data and Landsat TM are good source to provide information accurately. Under the utilization of potential land, increased population, and land conversion are the major driving forces for the change in land use during the past 10 years. This research work demonstrates the ability of GIS and Remote Sensing in capturing spatial-temporal data. Attempt was made to capture as accurate as possible five land use land cover classes as they change through time. From the temporal trajectories statistics, 60% of the study area was not changed, and 40% was changed by manmade processes due to Deforestation, increasing of Aquaculture and commercial activities. However, it should also be noted that since 1990s, the area of aquaculture has increased up to 2000 and the same trend continued up to 2009.Forests area has decreased from the year 1990 to 2009.In 1990 forest area is 16% and it is decreased to 12% in 2000 and 5% in 2009.This is mainly due deforestation. Due to increase in population agricultural area has been converted in to commercial area. The results suggest that in terms of affected area, the human impact on the environment was still relatively minor in this area, but if the same trend continues our future generations will be in threat due to scarcity of resources.
