What is Remote Sensing?
What is Remote Sensing?
Remote sensing acquires information about the Earth's surface by measuring reflected and emitted radiation without direct contact.
Passive vs. Active Remote Sensing
Passive vs. Active Remote Sensing
Passive sensors record naturally available incident radiation, while active sensors emit their own radiation and then record it.
