Define Resolution |
The ability of remote sensing system to record & display fine spatial, spectral, temporal, and radiometric detail.
|
|
|
Name the 4 resolution types |
*Spatial resolution
*Spectral resolution *Radiometric resolution *Temporal resolution |
|
|
What influences what you're observing? |
*Contrast *Shape *Ratio *Regularity of shape *Number of objects *Extent & uniformity of background |
|
|
Define SPATIAL RESOLUTION |
Refers to the size of the smallest possible feature that can be detected |
|
|
Ways of measuring spatial resolution? |
*GRD (Ground resolved distance) *Line Pairs per Millimeter (lp/mm) *MTF (“Modulation transfer Functions”) |
|
|
Define SPECTRAL RESOLUTION |
Width of spectral bands. Finer the spectral resolution, narrower the wavelength range for a particular channel or band. |
|
|
Define RADIOMETRIC RESOLUTION |
Describes the actual information content of an image. Finer the radiometric resolution of a sensor, more sensitive it is to detecting small differences in reflected or emitted energy. |
|
|
Define TEMPORAL RESOLUTION |
Revisit time: How long before sensor visits (can image) the same location
|
|
|
Temporal resolution is important for? |
-Vegetation/crop monitoring -Monitor flooding -Urban development -Deforestation monitoring |
