Absorption

The absorption of electromagnetic radiation (EMR) in the atmosphere is crucial for understanding how different gases and particles interact with incident radiation.

Transmission

Transmission refers to the process by which electric and electromagnetic radiation passes through the atmosphere and reaches the Earth’s surface, highlighting atmospheric windows and the impact of scattering and absorption.

Atmospheric Windows

Atmospheric windows are specific regions within the electromagnetic spectrum where radiation can effectively penetrate the Earth's atmosphere, making them ideal for remote sensing applications.

Spectral Signature Of Objects

The section covers the concept of spectral signatures, detailing how materials reflect and emit electromagnetic radiation across different wavelengths, which is vital in remote sensing.

Types Of Orbits

This section discusses the different types of orbits used for satellites in space-borne remote sensing, focusing on geosynchronous and sun-synchronous orbits and their applications.

Geo-Synchronous Satellites

Geo-synchronous satellites orbit the Earth at a fixed position relative to the surface, enabling continuous observation of a specific area.

Sun-Synchronous Satellites

Sun-synchronous satellites operate in low Earth orbits, allowing them to maintain a constant relationship with the Sun, which is essential for consistent imaging of the Earth's surface.

Types Of Remote Sensing Platforms

This section discusses the three main types of remote sensing platforms: ground-based, airborne, and space-borne platforms.

Ground Based Platforms

Ground based platforms are essential tools in remote sensing, providing detailed and localized data collection for environmental analysis.

Air-Borne Platforms

Air-borne platforms are critical tools used for data collection close to the ground, enhancing the resolution of remote sensing imagery.

Space-Borne Platforms

This section discusses Mie and non-selective scattering, absorption, transmission, and the significance of atmospheric windows in remote sensing.

Different Types Of Resolutions

This section discusses the four main types of resolutions in remote sensing: spatial, spectral, radiometric, and temporal resolution.

Spatial Resolution

Spatial resolution refers to the smallest size of an area on Earth's surface that can be distinctly recorded by a remote sensing sensor.

Spectral Resolution

Spectral resolution refers to a sensor's ability to define fine wavelength intervals, which is essential for characterizing different surface features in remote sensing.

Radiometric Resolution

This section discusses the concept of radiometric resolution in remote sensing, focusing on the role of scattering, absorption, and transmission of electromagnetic radiation in image quality.

Temporal Resolution

Temporal resolution refers to the frequency at which a satellite revisits the same area, impacting its ability to monitor dynamic changes.

Different Types Of Sensors

This section discusses the types of sensors in remote sensing, categorizing them into passive and active sensors and their subtypes based on several factors.
