ABSTRACT
Evaluation of land use and land cover using remote sensing and GIS techniques is
an area of interest that has been attracting increasing attention. This paper is an
attempted to show the changes in
Vijayawada city over a 6 year period. The study made use of land sat imageries of
2010 to 2016. Images classifications are supervised and unsupervised on satellite
images. The results show that degraded disturbed and
type of land use and land cover in the study area. The increasing population and
economic activities were noted that they are keeping pressure on the available land
resources. This paper highlights the importance of remote
in apprehending the situation in Vijayawada city.

The properties measured with remote sensing techniques relate to land cover, from which
land use can be inferred, particularly with ancillary data or a priori knowledge.
Land cover/use studies are multidisciplinary in nature, and thus the participants involved
in such work are numerous and varied, ranging from international wildlife and conservation
foundations, to government researchers, and forestry companies.
Regional government agencies have an operational need for land cover inventory and land
use monitoring, as it is within their mandate to manage the natural resources of their
respective regions.
Figure 1 Study area.
The purpose of this paper was to study the changes in land use and land cover over a period of
6 years in Vijayawada city using remote sensing and GIS techniques and deriving factors
behind the changes and the adverse effects of these changes on the livelihood of the people
and the local environment.
Study area
Vijayawada city situated at the geographical centre of Andhra Pradesh state in India on the
banks of Krishna River with latitude 16°31'N and longitude 80°39' E.

The topography of Vijayawada is flat with a few small to medium sized hills. Vijayawada
city is the present capital of the state of Andhra Pradesh due to this the population growth has
been rapidly increasing day by day.
The city’s population is expected to increases to 16.5 lakhs by 2021.With ever increasing
population and record growth of urban area the city’s landscape is undergoing unwanted
changes.
Build up of such excess heat in the urban area due to concentrated increased built-up
surfaces with concrete, asphalt, etc. and vegetative cover.
The city is facing severe land use troubles like shortage of disposal sites for garbage
whose daily production is around 600 metric tons. with the above mentioned problem related
to the unplanned growth of the city the study on land use and land cover.
MATERIALS AND METHODS
Data sources
An area of 61.88sqkm was delineated on the landsat scene covering the study area .The land
use and land cover mapping for the area was based primarily on land sat 5 Thematic Map
(TM) of December 2010 and Landsat 7 Enhanced Thematic Map (ETM) data of January
2016. The images were geometrically corrected to Universal Transverse Mercator (UTM)
coordinate system.
The selection of images of the same season was to minimize the influence of seasonal
variations on the result.
Digital image processing
Digital image processing study depended upon the use of computer-assisted explanation of
Land Sat imageries. Survey was performed throughout the study area using Global
Positioning System (GPS). This survey was performed in order to obtain accurate location
point data for each LULC class included in the classification scheme as well as for the
creation of training sites and for signature generation. In order to obtain the required
information from satellite image data, processing and interpretation were made
systematically.

The classification scheme is as described in Table 1. The post interpretation phase included
preparation of LULC maps and detection of their changes. The change detection technique,
which was employed in this study, was the post- classification compare- son. The overlay
consisting of LULC maps of 2010 and 2016 were made through ERDAS IMAGINE software.
RESULTS AND DISCUSSION
There are two image classifications. They are supervised and unsupervised. They are as
follows

Figure 4 and 5 shows the land use/land cover area by supervised and unsupervised images of
2010 and Figures 6 and 7 shows the land use/land cover images of 2016. Charts provide a
complete data set in terms of the overall landscape the types and extent of changes.
CONCLUSION
By comparing the images of Vijayawada city, Andhra Pradesh. From the years 2010 to 2016
by using the image classification methods like supervised and unsupervised for identifying the
changes in amount of land occupied by rivers, settlements and agricultural lands. After
comparing we got the amount land occupied by river in 2010 to 2016 is decreased from 748 to

600. The settlements are increased from 36105 to 38265 and agricultural land has been
decreased from 28683 to 24581. This changes indicates that the amount of land occupied by
both rivers and agriculture is getting decreased. The settlements are increasing day by day due
to the increase in population.
