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
Application of gis and remote sensing in agriculture
- 1. Topic of Presentation: ApplicAtions of Remote sensing And gis in AgRicultuRe By ReHAnA KHAliQ luciAn BlAgA univeRsity siBiu
- 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
- 5. GIS: OLD AND NEW Traditional GIS MAP TYPEWRITER MANUAL DRAFING TOOLS New GIS COMPUTER PLOTTER CD-ROM
- 6. 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. 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.
- 9. •Data Acquisition and prepossessing •Database Management and Retrieval •Spatial Measurement and Analysis •Graphic output and Visualization
- 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.
- 12. 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
- 13. 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.

- 24. 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
- 25. 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.
