Multispectral sensors capture images in multiple spectral bands, allowing for detailed analysis of land cover, vegetation, and other surface features.

Hyperspectral sensors collect data in hundreds or thousands of narrow spectral bands, enabling the identification of specific minerals and materials based on their unique spectral signatures.

Lidar (Light Detection and Ranging) sensors emit laser pulses to measure the distance between the sensor and the ground, providing accurate elevation data and 3D representations of the terrain.

Thermal sensors measure the temperature of the Earth's surface, allowing for the identification of urban heat islands, which are areas with higher temperatures due to human activities.

Microwave sensors are used in weather satellites to measure temperature, humidity, and precipitation, providing valuable data for weather forecasting and climate monitoring.

Passive sensors rely on natural energy sources, such as sunlight, to collect data, making them less expensive and easier to operate compared to active sensors, which require an external energy source to emit signals.

SAR (Synthetic Aperture Radar) sensors use radar technology to measure the backscattered energy from the ocean surface, providing information about ocean currents, sea surface temperature, and wave patterns.

Radar sensors are sensitive to weather conditions, such as rain and clouds, which can interfere with the radar signals and affect the quality of the data collected.

Multispectral sensors capture images in multiple spectral bands, allowing for the identification and classification of different types of vegetation and crops based on their unique spectral signatures.

Lidar sensors are used to create detailed 3D models of the Earth's surface, providing accurate elevation data and information about landforms, vegetation structure, and urban environments.

Thermal sensors measure the temperature of the Earth's surface, allowing for the detection of forest fires and deforestation, as these areas typically exhibit higher temperatures compared to surrounding areas.

Hyperspectral sensors collect data in hundreds or thousands of narrow spectral bands, providing a much wider spectral range compared to other types of sensors, enabling the identification of a broader range of materials and features.

Spectrometers measure the intensity of light at different wavelengths, allowing for the identification and quantification of various pollutants in the atmosphere based on their unique spectral signatures.

Microwave sensors are used to measure the temperature of the sea surface, providing valuable data for oceanographic studies, climate monitoring, and weather forecasting.

Multispectral sensors capture images in multiple spectral bands, allowing for the classification of different land cover types and the detection of changes in urban areas, such as new construction or changes in vegetation cover.
