3. WHAT IS REMOTE SENSING?
• Remote sensing is the science of obtaining the physical properties
of an area without being there. It allows users to capture, visualize,
and analyze objects and features on the Earth’s surface. By
collecting imagery, we can classify it into land cover and other
types of analyses.
• This technology is becoming increasingly important in plant
science research, as it enables the monitoring of large areas of
land and crops quickly and efficiently.

5. REMOTE SENSING TECHNIQUES
• Satellite Imagery
• LiDAR
• Hyperspectral Imaging
• Thermal Imaging

6. SATELLITE IMAGERY
• Satellite imagery involves the
use of satellites to capture
images of the Earth’s surface.
• These images can be used to
monitor vegetation patterns,
identify areas of stress, and
detect changes in land use.

7. LIDAR
• Light Detection and Ranging (LiDAR)
is a remote sensing technology that
uses lasers to measure the distance
between the sensor and the target.
• LiDAR can be used to generate 3D
maps of vegetation, including tree
height and canopy structure.

8. HYPERSPECTRAL IMAGING
• Hyperspectral imaging involves the use of sensors to
capture data from a range of wavelengths across the
electromagnetic spectrum.
• This technique can be used to identify specific plant
species, monitor crop health, and detect areas of stress.

10. THERMAL IMAGING
• Thermal imaging involves the use
of sensors to capture data on the
temperature of surfaces.
• This technique can be used to
identify areas of stress in plants,
such as water stress or disease.

11. APPLICATIONS OF REMOTE SENSING IN PLANT
SCIENCE
• Crop Monitoring and Management
• Biodiversity Monitoring
• Forest Management
• Carbon Sequestration
• Urban Green Spaces

12. CROP MONITORING AND
MANAGEMENT
• Remote sensing can be used to
monitor crop health and growth, as
well as to identify areas of stress.
• This information can be used to
optimize irrigation, fertilization, and
pest management practices.

13. BIODIVERSITY MONITORING
• Remote sensing can be used to
monitor changes in plant
species distribution and
abundance over time, as well
as to identify areas of high
biodiversity.

14. FOREST MANAGEMENT
• Remote sensing can be used to
monitor forest health, track
changes in forest cover, and detect
forest fires.

15. CARBON SEQUESTRATION
• Remote sensing can be used to
estimate the amount of carbon
stored in vegetation, which is
important for understanding the
role of plants in mitigating climate
change.

16. URBAN GREEN SPACES
• Remote sensing can be used to
monitor the health and growth of
trees in urban green spaces,
which can improve urban air
quality and mitigate the urban
heat island effect.
