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 other means.
Thus, a GIS can use combinations of mapped variables to build and analyze new variables.
GIS is most useful when used to perform data analysis
First developed in North America, particularly the U.S. and Canada in the mid-1960s
Previously been used in natural resources and environmental research

•Data Acquisition and prepossessing•Database Management and Retrieval•Spatial Measurement and Analysis•Graphic output and Visualization
• Maximize the efficiency of planning and decision making
• Provide efficient means for data distribution and handling
• Elimination of redundant data base - minimize duplication
• Capacity to integrate information from many sources
• Complex analysis/query involving geographical referenced data to generate
Geospatial data are better maintained in a standard format.
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.
Facilities Management: Locating underground pipes & cables, planning facility
maintenance, telecommunication network services Environmental and Natural Resources
Management: Environmental impact analysis, disaster management and mitigation
Street Network: Locating houses and streets, car navigation,
transportation planning Planning and Engineering: Urban planning, regional planning, development of
public facilities Land Information: Taxation, zoning of land use, land acquisition
Remote Sensing:◦ The art and science of obtaining information about an
object without physically contact between the object and sensor
◦ 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 Atmosphere.

Benefits
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 are sampling
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 development.
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 region.
