ASCBC DAY 5 TEST Flashcards
Which Organization provides weather products to Air Force and Army users?
55th Weather Wing - Offut, AFB, NE
Which organization provides weather products to the NAVY and MARINE users?
FNMOC
Fleet Numerical Meteorology and Oceanography Center - Monterey, CA
Which organization commands and controls all of our nation’s weather satellites, both MILITARY and CIVIL?
NOAA
COSPAS-SARSAT: Civil Search and Rescue Satellite between Russia, USA and other countries
What US weather satellites are in LEO?
DMSP (defense meteorological satellite program)
POES (polar operational environmental satellites)
NPP (national polar orbiting partnership)
Which satellites are capable of detecting nighttime lights?
DMPS
SUOMI NPP
Which satellite constellation hosts an experimental GPS Radio Occultation instrument that uses the GPS signal to depict atmospheric status?
NOAA - USA
NSPO Joint Program (National Space Organization) in Tiawan
COSMIC-2 is the constellation
Which US Weather Sat constellation is in GEO?
GOES (geostationary operational environmental satellite)
5 in orbit
provides meteorological data, space weather, operated by NOAA
what type of imagery has the best spatial resolution?
PAN (Panchromatic) uses visible light in grey scale
multi-spectral imaging provides unique capabilities to identify and differentiate materials on the ground based on their what?
Using Spectral signatures MSI can see in color. (can differentiate between turf and grass…or camo and foliage)
Spectral signatures is the variation of reflectance or emittance of a material with respect to wavelengths….a unique pattern of wavelengths radiated from an object.
What is spatial resolution?
the smallest distance between 2 objects where they appear separate and distinct.
what determines spectral resolution?
the more bands a sensor can break a portion of the spectrum into, the higher the resolution.
the # of bands ability to distinguish between wavelengths.
The ability of a sensor to define fine wavelength intervals. the finer the spectral resolution, the narrower the wavelength range for a particular channel or band.
In order: Broadband, multispectral, hyperspectral, ultra spectral.
spectral signature is like a fingerprint.
What does elevation data provide for satellite imagery?
adds precision. DTED –> Digital Terrain Elevation Data.
provides more precise geolocation, specifically to mountainous terrain.
Describe Change Detection?
How is Change Detection normally depicted in an image?
blue is new, red has fled
uses one location, two images…different time.
What is commercial imagery satellite has the best Electro-optical and spectral?
What are the details?
