When the instructor has determined that the groups have completed this task, the instructor will have students explain their definitions. See if they wish to adopt, or if they wish to modify a definition for use. Students successfully complete a concise definition which can be justified to the class during a group presentation. Instructor can, time permitting, discuss the possible drawbacks to remote sensing. An example might be the study of how microwaves radiation from satellites effects humans.
Instructor can also research the different ways that remote sensing images are created.
For example satellite imagery and Aerial photography are two ways that such information can be obtained.
