This document summarizes the applications of remote sensing and GIS in agriculture as presented by Rehana Khaliq. It discusses how GIS systems capture and analyze geospatial data to integrate information and perform analysis. Remote sensing is defined as obtaining information about objects without physical contact using sensors. The document outlines how remote sensing and GIS have been applied to agriculture for tasks like crop mapping and monitoring, yield estimation, and precision agriculture. It also discusses their applications in forestry, land use mapping, and urban planning. While remote sensing provides valuable data, it notes that measurement errors and data interpretation can sometimes be challenging. In conclusion, the document argues that remote sensing and GIS are promising tools to enhance sustainable agriculture and development through
2. 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.
3. 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
4. First developed in North America, particularly the
U.S. and Canada in the mid-1960s
Previously been used in natural resources and
environmental research

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
might happen.
intense competition
◦ the need to use technology in making decisions and
strategy in the world of intense competition.
10. • 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
11. 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.

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.

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.
