GEOGRAPHICAL INFORMATION SYSTEM

A GIS (Geographical Information System) canbe described as a computer mapping and datastorage system, in which data is tied to points,

lines, polygons or pixels on a computer display


3/22

THE HISTORY

First developed in North America,particularly the U.S. and Canada inthe mid-1960s

Previously been used in naturalresources and environmental research

THE NEED FOR GIS

the real world has a lot of spatial data manipulation, analysis and modeling can be

effective and efficiently carried out with a GIS

the neighborhood of the intended purchase of house

the route for fire-fighting vehicles to the fire area location of historical sites to visit

the earth surface for purposes of army

the earth surface is a limited resource rational decisions on space utilization fast and quality information in decision making


7/22

GIS APPLICATION (I)

environment management of natural resources

land, forest, marine, etc.

monitoring/control of environmental pollution

environment impact study

infrastructure

transport and irrigation management andmaintenance

utility management and maintenance

electric, water, gas, telephone, etc.


8/22

GIS APPLICATION (II)

socio-economy

town and country planning

monitoring of population migration

disperse of resources/servicesclinics, schools, etc

military

land form visualisation

visibility analysis


9/22

BENEFITS OF GIS

improves/enhances the effects of

physical/environmental growth better management of resources

adding new value-added services

perform analysis on spatial and non spatial

components fast recall of data

ability for complex analysis

recalling of non spatial data through object location

display of information in a different light/view multiple scenario in planning can be performed

easily

Agriculture Sector is changing the socio-economic environments of the population dueto liberalization and globalization

About 75% people are living in rural areasand are still dependent on Agriculture. About43% of Indias geographical area is used foragricultural activity

Agriculture continues to play a major role inIndian Economy

Indian Agriculture


11/22

INDIAN AGRICULTURE

Provides about 65% of the livelihood

Accounts for 27% of GDP

Contributes 21% of Total Exports,and Supplies Raw materials toIndustries

Growth Rate in production - 5.7% Food grains production 211.17 mt

INFORMATION SYSTEMSREQUIREMENT IN AGRICULTURE

GIS/RS based Systems:

Soil and Land use

Watershed developmentsDisaster management

Cropping systems

Agriculture Resources InformationOrganic farming (bio-fertilisers)

Crop weather watch


16/22

FIELD MAPPING

Position data (georeference data)recorded at predetermined intervals.

Other data recorded manually or

automatically by monitor, computer, ordata logger.

Data displayed by geographic information

system (GIS) in thematic map format.


17/22

SOIL SAMPLING

Georeferenced soil samples can becollected

Sampling MethodsGrid sampling: intensive sampling of entire

field

Directed sampling: intensive sampling of

particular target areas


18/22

YIELD MAPS

Record of spatial yield variability within afield or farm.

GPS data coupled with yield data toproduce map.Mechanically harvested

Hand harvested

Useful tool for decision making.

COTTON YIELD MAP


20/22

FIELD SCOUTING

Fields can be scouted for a variety ofpests

Pest populations recorded on maps

Decision tools can be applied on a sitespecific basis


21/22

VARIABLE RATE CONTROL

Application rates designed for needs ofsmall sections of a field

GPS determines position of equipment inthe field

Computer controls use GPS data andprescription files to adjust rate
