The spectral signature of an object is a function of the incidental EM wavelength and material interaction with that section of the electromagnetic spectrum.

2019年8月21日 · Such plots are called “spectral response curves” or “spectral signatures.” Differences among spectral signatures are used to help classify remotely sensed images into classes of landscape features since the spectral signatures of like features have similar shapes.

One of the best spectral signature cheatsheets that exist today. Today, we explore the visible – and invisible. Whether it’s near-infrared or the cirrus band, use this clear and concise guide to spectral signatures. This way, you’ll be able to extract …

Any remotely sensed parameter, which directly or indirectly characterizes the nature and/or condition of the object under observation, is defined as its signature. We actually use the spectral signature of the object in remote sensing. This can be defined as a unique pattern of wavelengths radiated by an object. These can be categorised as.

A spectral signature is typically visualized as a graph which displays the intensity of light at different wavelengths that is collected from the material. By analyzing these spectra, we can discern unique patterns that serve as identifiers for specific materials.

The shape of the spectral response and its characteristics as a function of wavelength λ is called the spectral signature of the object or phenomenon. Fig. 3.5 presents various such spectral signatures for some Earth surface materials.

A spectral signature is a function of the wavelength and is defined as the ratio of reflected radiation energy [E r (λ)] to incident radiation energy [E t (λ)] on an object. All matter on earth's surface has separate values of spectral reflectance characteristics.

Spectral signatures are the combination of reflected, absorbed and transmitted or emitted EMR by objects at varying wavelengths, which can uniquely identify an object.

Spectral signatures are the specific combination of reflected, absorbed and transmitted or emitted EMR by objects at varying wavelengths, which can uniquely identify an object.

The spectral signature – usually reproduced graphically – is the characteristic of the reflection of an object with regard to the relationship of the wavelength and the reflectance.
