Electromagnetic Radiation: The behavior and properties of electromagnetic radiation that is emitted or reflected from the Earth's surface or atmosphere and detected by sensors on remote sensing platforms.
Spectral Signatures: The unique spectral reflectance characteristics of different features on the Earth's surface that can be used to identify and distinguish them using remote sensing data.
Resolution: The level of detail or granularity captured by a remote sensing sensor, measured in terms of spatial, spectral, and temporal resolution.
Platforms: The types of vehicles or devices used to capture remote sensing data, such as satellites, aircraft, drones, and ground-based sensors.
Image Classification: The process of assigning pixels in a remote sensing image to specific land cover or land use categories based on their spectral characteristics, often using machine learning algorithms.
Atmospheric Correction: The process of removing or mitigating the effects of the atmosphere on remote sensing data, in order to improve the accuracy and reliability of measurements.
Data Fusion: The integration of data from multiple sensors or platforms, often with different spatial, spectral, and temporal resolutions, to improve the overall quality and usefulness of remote sensing data.
