The Imaging Spectrometer Data Analysis System is an image and spectral analysis system developed by the Canada Centre for Remote Sensing. ISDAS processes data from any airborne or spaceborne hyperspectral sensor that acquires data in the visible, near infrared, and shortwave infrared wavelength regions.

OBS

ISDAS est un outil d'analyse d'image et de signature spectrale mis au point par le Centre canadien de télédétection. Le système ISDAS fait le traitement de données hyperspectrales acquises de capteurs aéroportés et spatioportés opérant dans le visible, le proche infrarouge et l'infrarouge à ondes courtes.

CONT

During the European Multisensor Airborne Campaign 1994(EMAC 94), the Experimental Synthetic Aperture Radar(ESAR) and the Reflective Optics System Imaging Spectrometer(ROSIS) were flown over an experimental catchment in Belgium. Concurrent to the ESAR overflights, field data were collected in two subcatchments of the Zwalmbeek. The main objective of this remote-sensing experiment was to retrieve spatial information of surface soil moisture content.

Subject field(s)
  • Remote Sensing
DEF

The science and techniques involved in using imaging spectrometers.

CONT

Imaging spectrometry ... is the field in remote sensing where sensors acquire image data in many, narrow and contiguous wavebands. The aim is to produce on a pixel by pixel basis radiance and reflectance data, which can be used to model physical properties of the Earth surface. This data forms an addition to subsurface geophysical data.

OBS

Imaging spectroscopy has many names in the remote sensing community, including imaging spectrometry, hyperspectral, and ultraspectral imaging. Spectroscopy is the study of electromagnetic radiation. Spectrometry is derived from spectro-photometry, the measure of photons as a function of wavelength, a term used for years in astronomy. However, spectrometry is becoming a term used to indicate the measurement of non-light quantities, such as in mass spectrometry(e. g. Ball, 1995). Hyper means excessive, but no imaging spectrometer in use can hardly be considered hyper-spectral, after all, a couple of hundred channels pales in comparison to truly high resolution spectrometer with millions of channels. Ultraspectral is beyond hyperspectral, a lofty goal that has not yet been reached.... Researchers at the USGS Spectroscopy Lab are studying and applying methods for identifying and mapping materials through spectroscopic remote sensing(called imaging spectroscopy, hyperspectral imaging, imaging spectrometry, ultraspectral imaging, etc), on the Earth and throughout the solar system using laboratory, airborne and spacecraft spectrometers.

OBS

imaging spectrometry; imaging spectroscopy; hyperspectral imaging: terms officially approved by the RADARSAT-2 Terminology Approval Group (RTAG).

DEF

Utilisation de la radiométrie spectrale pour obtenir des images potentielles ou réelles d'une scène.

OBS

Les dernières découvertes en matière de télédétection (comme l'apparition des appareils de radiométrie spectrale imageante à haute résolution) nous permettent d'acquérir des données plus détaillées sur les écosystèmes des milieux humides, concernant en particulier la forme et les dimensions des zones humides, la portée et la distribution de la végétation des milieux humides, les types de végétation qui s'y trouvent et l'utilisation des terres adjacentes.
