Properties of Light
The Electromagnetic Spectrum shows this
What is "Wavelenghts of light"
Spatial resolution is useful for showing this
What is "Detail"
This part of a map shows this correlation of the size of a feature on a map to the size of that feature in real life
What is "scale"
What is the difference between active and passive sensors
passive sensors use light from earth and active sensors use their own radiation
This type of satellite orbit is used by the Landsat satellites and is useful for earth imaging.
What is "Low Earth Orbit"
Polarization aligns these two fields
Temporal resolution is useful for showing this
What is "Change"
only being able to be used during the day is a disadvantage of this type of image
What is "true color"
Give an example of passive sensors
optical and infrared sensors
GPS satellites use this orbit
What is "Middle Earth Orbit"
Infrared is used to monitor this quality
What is "vegetation health"
Radiometric resolution is useful to show this
What is "values"
False Color maps (especially in infrared) are helpful to show ___
What is "vegetation health"
Give an example of an active sensor
Radar or lidar
The main difference between polar and nonpolar satellites :
What is "where they travel"
Light is carried by this particle
What is a "photon"
Spectral resolution is useful for showing this
What is "Colors"
When contours on a map are closer together this means that the slope is ____
What is "steeper"
What is the difference between radar altimetry and SAR?
direction of capture
This type of satellite orbit makes it appear as if the satellite stays at a fixed point in the sky.
What is "GEO"
This effect causes the sky's color
What is "Rayleigh scattering"
If you have a higher spectral resolution, this is called:
What is "Bands"
Which of the missions we learn about was used for topograpghy? (hint: its got RADAR in its name)
What is "SRTM" (sorry if no one got that I had hard time making up questions)
What is the difference between SAR and InSAR?
InSar measures ground deformation
GSEO's have this advantage over GEOs
What is "better polar covergage"
