ESRI D2M Part 1 - Fundamentals of Remote Sensing (3-12)

What is remote sensing?

• Direct measurement of an object by touching it

• Measurement of a quantity associated with an object by a device not in direct contact with the object

• Using a microscope to observe small objects

• Measuring temperature with a thermometer

Which factor determines the most useful platform for remote sensing?

• The color of the object

• The application

• The size of the object

• The cost of the device

What do satellites and drones carry to measure electromagnetic radiation?

• Cameras

• Instruments or sensors

• Antennas

• Solar panels

What type of energy do satellites and drones measure from the earth-atmosphere system?

• Kinetic energy
