Required specification on food and land use
Remote Sensing is a useful tool to monitor land use and land change on
ground surface under limitation of parameters.
RS data should be taken by area size, resolution, physical value, density.
New satellites and sensors are coming up. mid-range platform is also.
What specification is required on food production and land use?
Parameters
Spacial Information:
Ground Resolution, Positioning accuracy,
Observation area, Stereoscopy
Frequency of observation:
Band width, band numbers
Spectral characteristics: pointing, multiple satellite operation
