Geographic Information System
A GIS is a computer system capable of capturing,
storing, analyzing, and displaying geographically
referenced information; that is, data identified
according to location.
Practitioners also define a GIS as including the
procedures, operating personnel, and spatial data that
go into the system.
A GIS makes it possible to link, or integrate,
information that is difficult to associate through any
Thus, a GIS can use combinations of mapped
variables to build and analyze new variables.
GIS is most useful when used to perform data
First developed in North America, particularly the
U.S. and Canada in the mid-1960s
Previously been used in natural resources and
GIS: OLD AND NEW
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
complexity of management
◦ due to the need to combine and process many sets of data,
in addition to judge as many as possible, situation that
◦ the need to use technology in making decisions and
strategy in the world of intense competition.
•Database Management and Retrieval
•Spatial Measurement and Analysis
•Graphic output and Visualization
• Maximize the efficiency of planning and
• Provide efficient means for data distribution and
• Elimination of redundant data base - minimize
• Capacity to integrate information from many
• Complex analysis/query involving geographical
referenced data to generate
Geospatial data are better maintained in a standard
Revision and updating are easier.
Geospatial data and information are easier to search,
analysis and represent.
More value added product.
Geospatial data can be shared and exchanged freely.
Productivity of the staff improved and more efficient.
Time and money are saved.
Better decision can be made.
Locating underground pipes & cables, planning facility
maintenance, telecommunication network services
Environmental and Natural Resources Management:
Environmental impact analysis, disaster management
Locating houses and streets, car navigation, transportation
Planning and Engineering:
Urban planning, regional planning, development of public facilities
Taxation, zoning of land use, land acquisition
◦ The art and science of obtaining information about an
object without physically contact between the object and
◦ The processes of collecting information about Earth
surfaces and phenomena using sensors not in physical
contact with the surfaces and phenomena of interest.
◦ There is a medium of transmission involved i.e. Earth’s

Expensive to build and operate!!!!
Measurement uncertainty can be large
Data interpretation can be difficult
need to understand theoretically how the instrument is
making the measurements
need to understand measurement uncertainties
need to have some knowledge of the phenomena you
Recent developments in remote sensing and GIS hold much promise to
enhance integrated management of all available information and the
extraction of desired information to promote sustainable agriculture and
GIS is considered one of the important tools for decision making in problem
solving environment dealing with geo-information.
Remotely sensed images can be used to identify nutrient deficiencies,
diseases, water deficiency or surplus, weed infestations, insect damage, hail
damage, wind damage, herbicide damage, and plant populations.
Remote Sensing and GIS technology is very effective tool for suggesting
action plans /management strategies for agricultural sustainability of any
