What is remote sensing?

• Remote sensing is the process of physically touching and measuring objects.

• Remote sensing is the study of human behavior in urban areas.

• Remote sensing is the acquisition of information about an object or area from a distance, often using satellite or aerial imagery.

• Remote sensing involves only ground-based observations without any technology.

Name two main types of remote sensors.

• Satellite sensors and drone sensors

• Passive sensors and active sensors

• Thermal sensors and optical sensors

• Ultrasonic sensors and radar sensors

What is the difference between passive and active remote sensing?

• Passive remote sensing requires a power source to operate.

• Active remote sensing sends out signals to measure reflections, while passive remote sensing detects natural radiation.

• Active remote sensing only measures temperature changes.

• Active remote sensing relies solely on sunlight for data collection.

How do satellites acquire data for remote sensing?

• Satellites rely on weather balloons for data collection.

• Satellites use ground-based cameras to capture images.

• Satellites use sensors to detect electromagnetic radiation from the Earth's surface.

• Satellites transmit data only during nighttime.

Describe one method of data acquisition in remote sensing.

• Satellite imagery is a method of data acquisition in remote sensing.

• Ground-based surveys are a method of data acquisition in remote sensing.

• Aerial photography is a method of data acquisition in remote sensing.

• Weather balloon data collection is a method of data acquisition in remote sensing.

What are the main components of a remote sensing system?

• The main components of a remote sensing system are sensors, platforms, data processing units, and user interfaces.

• Weather monitoring stations

• Cameras and microphones

• Satellite navigation systems

Explain the significance of image resolution in remote sensing.

• Image resolution only affects color accuracy, not detail.

• Higher resolution images are always more expensive to obtain.

• Image resolution is significant in remote sensing as it affects the level of detail and accuracy in capturing and analyzing Earth's features.

• Image resolution is irrelevant in remote sensing.

What is image processing in the context of remote sensing?

• Image processing involves creating 3D models from images.

• Image processing in remote sensing is the analysis and manipulation of satellite or aerial images to extract information about the Earth's surface.

• Image processing is the study of image compression techniques.

• Image processing is only used for enhancing photographs.

List two common image processing techniques used in remote sensing.

• Image stitching

• Image classification, Image enhancement

• Image compression

• Image filtering
