Earth resource satellites are supposed to monitor and collect data on the natural resources, environment, and human activity of Earth. These are taken into different types considering the nature of data collected and the technology used. These types include:
Purpose: They record images of the Earth’s surface using visible and infrared light.
Usage: Used mainly for vegetation monitoring, urban planning, agriculture, and land-use studies.
Examples: Landsat series, Sentinel-2.
Function: It uses radar signals to map the Earth’s surface; it can look through clouds and functions under all weather conditions even at night.
Usage: Terrain mapping, monitoring deforestation, land subsidence, movements of ice sheets, and locating oil spills.
Examples: Sentinel-1, RADARSAT.
Function: The satellites can capture the wide spectrum of light and spread it over hundreds of narrow bands, so they can detect the chemical composition and specific material.
Usage: It is used for mineral exploration, agricultural analysis, discovery of pollution, and water quality monitoring.
Examples: EO-1 Hyperion, PRISMA.
Function: They can measure the thermal (infrared) radiation emitted by objects on Earth by sensing surface temperatures.
Usage: It is used for monitoring wildfires, urban heat islands, volcanic activities, and changes in ocean temperature.
Examples: Landsat 8’s TIRS (Thermal Infrared Sensor), ASTER.
Function: Surface height of Earth distance, with a special focus on oceans, using radar or laser altimetry.
Applications: Sea level rise studies, oceanic circulation, ice sheet height monitoring, among others, and elevation changes over land.
Examples: Jason series CryoSat
All types of satellites yield rather different kinds of measurements and are often complemented with one another to achieve a more detailed understanding of Earth’s resources and environment.
