The practical application of remote sensing is to answer a question about an object or phenomenon by observing and collecting information without coming into direct contact with the object of study.
For example, you go to dentist because of a sore tooth. You may ask, "do I have a cavity?"
The dentist can answer this question directly by drilling a hole in your tooth to search for any decay or he or she could use a remote sensing technique such as taking an X-ray and seeing if the cavity appears in the photograph.
