• Remote Sensing can aid in
• Indication of health of plants
• Control of pests and disease
• Determine when to spray, plough, or reap
• Asses damage from natural disasters
• Prediction of market factors

Applications Agriculture

• Two forms of agricultural remote sensing
• Strategic
• Operational

Department of Geomatics Remote Sensing
Applications Agriculture

• Strategic Agricultural Remote Sensing
• Involves large areas
• Concerned with overall crop estimates not day to
  day management
• Province of governments and large companies
• eg. L.A.C.I.E./ AgRISTARS project

Applications Agriculture

• L.A.C.I.E./ AgRISTARS project
• In 1977 the project tested the soviet wheat yield
  predictions
• Wheat is 48 of Russian grain gt102 million tonnes
• 1977 Soviet prediction - 213.3 m tonnes (13
  increase on 1971-76 average
• L.A.C.I.E. estimate - 91.4m tonnes
• Actual yield - 92m tonnes

Applications Agriculture

• L.A.C.I.E./ AgRISTARS project
• Demonstrated that the global monitoring of food
  and fibre production is possible
• Now used as a regular and routine tool

9
Department of Geomatics Remote Sensing
Applications Agriculture

• Operational Agricultural Remote Sensing
• Involves single farms or even fields
• Concerned with day to day management
• Involves individual farmers
• Cost and timeliness important
• Light aircraft/ videography
