DISTRICT-WISE CHANGE ANALYSIS OF LAND USE-LAND COVER IN DELHI TERRITORY USING REMOTE SENSING & GIS

摘要

Digital change detection is the process that helps in determining the changes associated with Land use and Land cover properties with reference to geo-referenced multitemporal remote sensing data. It helps in identifying change between two or more dates that is uncharacterized of normal variation. This work is an attempt to assess the district-wise changes in land use/land cover in Delhi, India. The study made use of LISS -III imageries of 2008 and 2012 year. The images were classified using Maximum Likelihood classification method. The output can be useful in many applications such as Land use changes, habitat fragmentation, rate of deforestation, urban sprawl and other cumulative changes through spatial and temporal analysis. The study shows that Delhi land cover in duration of 2008 to 2012 show major changes in the landscape as there is high growth in the fallow and built up area. Agriculture land decreased by 4.5% and forest area has reduced marginally by 1.5%, Built up increased by 1.8% and water body is showing almost a constant condition over time.
