1. Definition of Spatial resolution Smallest possible feature that can be
detected
in an image, defined by pixel size
2. The three components of spectral 1. # of spectral bands 2. Location on
resolu- tion
EMS 3. Bandwith of each band
3. First LANDSAT satellite Launched in 1972 and is longest
record of satellite data
4. What is something very high spatial Specific tree cover or plants
reso- lution satellite imagery can
observe (that coarse/moderate
imagery could not)
5. Give two examples of objects or phenom- Tree cover, neighbourhood. Street
or Park.
ena that can be observed at each specific tree or house
of the followingspatial resolutions:
1km, 250m, 30m
6. Explain the difference between active and Active remote sensors provide their
own ener-
passive remote sensing gy. It emits a form of radation. Passive sensors
gte energy from the sun
7. What are 2 advantages and 2 Pros: Weather independent (for RADAR), Can
disadvan- tages of active remote penetrate vegetation. Cons: Limited
sensing technolo- gies spectral info, Expensive
8. What portion of the EM spectrum is Microwave portion
used by RADAR?
9. What three key components are used in a Laser ranging, Positioning
(GPS), Inertial
