ABSTRACT:
Remote sensing and GIS based study can be effectively utilised for mapping and monitoring of natural resources. In the present
study an attempt has been made to map the status of different land use/ land cover pattern of Vishakhapatnam district of Andhra
Pradesh, India using Indian Remote Sensing Satellite data (IRS 1D LISS III) of November, 2000 and Survey of India (SOI)
topographical map. The study reveals about 59% of the total geographical area of the district are used by extensive agriculture,
regarded as croplands. The forest cover occupies an area of 2550.75 sq. km. Other categories found in the study area are Settlement,
Wastelands, water bodies, coastal Sandy areas and marshy areas cover the rest part of the area.
1.INTRODUCTION
Over exploitation of land resources causes a significant change
to the landforms, which has adverse effect to the environment.
As the land resources have been sole source of sustainance of
mankind, timely mapping and monitoring of land forms
become a prime requisite for the management and development
of these resources. In recent years, the spatial distribution
pattern and locational aspects of land use/ land cover can be
studied more accurately by using Remote sensing technique.
Remote sensing technology has emerged as an important tool in
recent times for monitoring and management of these natural
resources. The effect of topography, spatial / spectral resolution
and atmosphere are some of the scene and sensor dependant
issues that always hinder and influence the ability to map land
use/ land cover from the remotely sensed data accurately.
Selecting appropriate season and sensor could solve some of
these problems (Kushwaha and Madhavan, 1986; Rao, 1990;
Sudhakar et.al., 1992). In the present study, an attempt has
been made to monitor the land use/ land cover pattern of
Visakhapatnam district, Andhra Pradesh, India.
