Transcript of Remote sensing in Agriculture

Remote Sensing in Agriculture
Evolution
Current use
“Remote sensing is the science (and to some extent, art) of
acquiring information
about the Earth's surface
without
actually being in
contact
with it. This is done by sensing and recording reflected or emitted
electromagnetic radiation
and processing, analyzing, and applying that information” CCRS


How it works
The key is the different interaction of materials within the electromagnetic spectrum

Gives unique
photographs (VIS)
spectral signatures (VIS-MIR)
Photography
Methods
Balloons
Aeroplanes

Application
Crop identification

Imaging Spectroscopy
Used to map specific materials by detecting specific chemical bonds. (USGS, 2002)

Simultaneous registration of ‘reflectance’ images. (Wageningen UR, 2014)
Spectral Signatures

R.S. In Agriculture
A tool to help obtain data in order to
identify and monitor crops
in agricultural practices

An understanding of the
temporal and spatial

variations
of agricultural land cover

Important in the
decision making
of agricultural strategies
Precision farming
“Information and technology-based agricultural management system to improve crop production efficiency.” (Metternicht, 2006)

Case Studies
Developed
Limitations
Resolution (Spatial and Temporal)
Costs
Data error

Lag time
Heterogeneity of cropland
Data availability
User knowledge/usability
Not universal/appropriate
Privacy
Awareness of limitations

Global food demand

Advances in technologies
Multi-sensor studies
Improve hardware, software
Drones
Implanting nano-chips

Real-time fertilization

Biogeochemical fluxes

Future directions
Developing

Need to
Establish ground truth
Visualize: e.g. Normalize data using Vegetation Indices.

Applications
Identification
Monitoring
Yield estimation and prediction

Recognizing site variability through enhanced imagery and multi- temporal analysis

Determining the cause of such variability and ‘problem areas’ in crop production

Cost efficient/effective tool

Additionally helps protect the environment

Summary
The
progression
of Remote Sensing since it's beginning has led to the following in the
agricultural
sector;
More frequent use
