2. GEOGRAPHIC INFORMATION SYSTEM
A spatial data handling system .
A computer assisted system for the capture ,
storage , checking, integrating, retrieval,
manipulating, analysis and display of spatial data
from the real world.
A computerized information storage , processing
and retrieval system that have hardware and
software specially designed to cope up with
geographically referenced spatial data and
corresponding attribute information.
3. FUNCTIONS OF GIS
Stores data with Geo referencing
Process the data
Classifies the data
Overlay analysis
Updating of information
Integration of spatial and non-spatial map
Querying integration of remote sensing data
and maps
Planning.

6. GIS Application in
Agriculture
GIS can be used to create
more effective and efficient
farming techniques.
It can also analyze soil data
and to determine.
It is fully integrated and
widely accepted for helping
government agencies to
manage programs that support
7.
8. GIS APPLICATION IN URBAN
PLANNING
GIS technology is used to
analyze the urban growth and its
direction of expansion and to find
suitable sites for further urban
development.
Land should have proper
accessibility , land should be more
or less flat, land should be vacant
or having low usage value
presently and its should have good
supply of water.
10. TRANSPOTATION PLANNING
GIS can be used in managing transportation and
logistical problems.
It transport department is planning for a new
railway or a road then this can be performed by
adding environmental and topographical data into
the GIS platforms.
GIS can also help in monitoring rail system and
road conditions.

12. CONCLUSION
GIS makes easier to get valuable information about the
study area.
GIS enables us to integrate different layers and to
manage large database
It gives more accurate results when compare to
convectional methods.
Hence GIS is proved to be a powerful tool in
managing spatial and non – spatial databases in suitability
