5. History
1858 Balloonist G.Tournachon made photographs of
Paris from his balloon.
Systematic aerial photography developed for military and
reconnaissance purposes beginning in World War I and
reaching a climax during the Cold War .
Artificial satellites in the latter half of the 20th century.
9. signatures produced by wavelength-dependent
absorption.
the ratio of reflected energy to incident energy as a
function.
10. radiant energy that is measured by an aerial or
satellite sensor
electromagnetic energy returned from the Earth’s
surface can be detected by a light-sensitive film.
11. a function of the design of the sensor
detectors in a remote sensor measures energy received
from a finite patch of the ground surface
12. Parallel sensor arrays detecting radiation in a small
number of broad wavelength bands
allow discrimination of different types of : vegetation,
rocks and soils,
clear and turbid water, and
some man-made materials
13. Quantized incoming energy
analyze the numerical values in the bands of a
multispectral image
15. System Used
Optical System
Panchromatic imaging system
Multispectral imaging system
Super spectral Imaging System
Hyper spectral Imaging System
RADAR System
LiDAR System
16. Optical Remote System
Optical remote sensing makes use of visible, near
infrared and short-wave infrared sensors to form images
of the earth's surface by detecting the solar radiation
reflected from targets on the ground.
17. Panchromatic Imaging System
A single channel sensor is used to detect radiation
If range of wavelength and the visible range become
same then the imagery will appear as a black and white
photograph taken from space
18. Multispectral Imaging System
Uses a multi channel detector and records radiation
with a narrow range
Brightness and color informatics are available
