Analysis and verification of RS data
There are three main types of analyses applied to remotely
sensed data:
- Measurement - values
detected by sensors are used to calculate environmental conditions eg
surface temperature, soil moisture, condition of crops, quantity of
plant material
- Classification - regions
with the same characteristics are defined and grouped together
- Estimation -
is commonly applied to the results of classification. This process is
used to estimate quantities of different materials or groups.
An indication of how accurate the results are is needed to substantiate the results. Confidence in classification for example can be achieved from ground truthing; that is by going out into the area that has been mapped by remote sensing, and recording what is present on the ground.
