The sensor is the component of a remote sensing system that is responsible for collecting data about the Earth's surface. This data can be in the form of images, spectra, or other measurements.

Thermal sensors are not typically used in remote sensing, as they are not able to collect data about the Earth's surface from a distance.

The platform is the component of a remote sensing system that carries the sensor and moves it over the area of interest. This can be done by an aircraft, satellite, or other type of vehicle.

Ground vehicles are not typically used as platforms in remote sensing, as they are not able to collect data from a distance.

The data processing system is the component of a remote sensing system that processes and analyzes the data collected by the sensor. This can involve correcting for errors, enhancing the data, and extracting useful information.

Feature extraction is not a type of data processing technique used in remote sensing. It is a process of identifying and extracting useful information from the data.

The data display system is the component of a remote sensing system that displays the data in a visual format. This can be done using a variety of methods, such as maps, charts, and graphs.

Tables are not typically used as data display systems in remote sensing, as they are not able to display data in a visual format.

The primary purpose of a remote sensing system is to provide information about the Earth's surface. This information can be used for a variety of purposes, such as land use planning, environmental monitoring, and disaster response.

Remote sensing technology cannot provide data about the Earth's surface in real time. It can only provide data about the Earth's surface that was collected at a specific point in time.

The three main types of remote sensing systems are active, passive, and semi-active. Active systems emit their own energy, while passive systems detect energy that is reflected or emitted by the Earth's surface. Semi-active systems emit energy, but they also detect energy that is reflected or emitted by the Earth's surface.

Radar sensors are an example of an active remote sensing system. They emit their own energy, which is reflected by the Earth's surface and detected by the sensor.

Optical sensors are an example of a passive remote sensing system. They detect energy that is reflected or emitted by the Earth's surface.

Lidar sensors are an example of a semi-active remote sensing system. They emit their own energy, but they also detect energy that is reflected or emitted by the Earth's surface.

Spatial resolution is the size of the pixels in an image, while spectral resolution is the number of different wavelengths of light that the sensor can detect.
