Remote Sensing Concepts and Applications

The video introduces remote sensing, explaining its definition, components, and process. It covers types of imagery, including photo and non-photo, and classifies them based on various criteria. Examples of satellite imagery are provided, highlighting their applications. The video concludes with encouragement for learning geography.

What is the primary purpose of remote sensing?

• To directly interact with objects

• To replace traditional maps

• To obtain information about objects without direct contact

• To create physical models of objects

Which of the following is a component of remote sensing?

• Ocean currents

• Weather patterns

• Energy source

• Animal migration

In remote sensing, what is the role of the atmosphere?

• It acts as a barrier to energy

• It is the medium through which energy travels to the Earth's surface

• It stores data collected by sensors

• It generates energy for sensors

What is the first step in the remote sensing process?

• Data analysis

• Data delivery to users

• Object recording

• Energy transmission through the atmosphere

How are photo images in remote sensing typically captured?

• Using electromagnetic waves

• Through satellite signals

• With a camera from aircraft or drones

• By manual sketching

What distinguishes non-photo images in remote sensing?

• They are always in color

• They rely on electromagnetic waves instead of cameras

• They are only used for weather monitoring

• They are captured using traditional cameras

Which type of photo image is used to detect oil spills?

• Orthochromatic photo

• Panchromatic photo

• Ultraviolet photo

• Infrared photo

What is a characteristic of a vertical aerial photo?

• The camera axis is parallel to the Earth's surface

• The camera axis is perpendicular to the Earth's surface

• It is always taken from a satellite

• It shows the horizon line

Which satellite is used for planetary sensing?

• Viking

• Landsat

• SheSat

• NOAA

What is the purpose of the Landsat satellite?

• To monitor weather patterns

• To detect natural resources

• To explore outer space

• To provide internet services
