RS - Definition
|
Process of collecting data about objects or landscape features without coming into direct physical contact w/ them. Performed from orbital or sub-orbital platforms using instruments which measure emr reflected or emitted from terrain.

1st Order Elements
|
Tone: variation from white to black
Color: multitude of combinations of hue, value, and chroma Resolution: ability of entire photo system to render sharply defined image (factors: lens, exposure, processing, etc.) |
|
|
2nd Order Elements
|
Size: When other features blurred, size important in discrimination of objects
Shape: also provides diagnostic clues to aid ID Texture - frequency of change and arrangement of tones (impression of smoothness or roughness of an area) Pattern: spatial arrangement of objects |
|
|
3rd Order Elements
|
Site:
Association: I of one object indicates existence of another Height Shadow: Shadow patterns can help ID objects |
|
|
Point Scale
|
The scale at a point with a specific elevation on the ground
Photo take over rugged terrain will display varying range of scales associated w/ variations in elevation |
|
|
Stereoscopy
|
Science/Art that deals w/ use of binocular vision for observation of overlapping photographs
'normal' eyesight = stereoscopic vision Ability to see depth |
|
|
Spatial Resolution
|
Measurement of minimum distance between two objects that will allow them to be differentiated from one another in an image
|
|
|
Spectral resolution
|
# and size of EMR bands that can be recorded by a sensor
|
