Change Detection Analysis of Vegetation Cover
in Ersama and its Adjoining Area Jagatsinghpur, Orissa
ABSTRACT
The impact of natural calamities on the environment is of grave concern as it affects the culture and
livelihood of all the inhabitants.
This paper attempts to study the changes in the vegetation of Ersama and its
surrounding areas, Jagatsighpur, Orissa, following the cyclone disaster of 1999. Ersama was one of the areas most affected by
the cyclone. The present study is a continuation of a study using GIS and Remote-sensing in change detection analysis in the
vegetational cover taking both pre-cyclone and post cyclone data of Ersama.
High-resolution satellite data are used
for generation of maps as well as for data on vegetation and climatic changes. Temporal multi-spectral data show reduction in
vegetation. The management plan has been prepared using natural resource data and other parameters, which indicates the
alternative land utilization for controlling afforestation and management of an area.
