3. Background
 First Surveying Satellite (Landsat)
The first Landsat satellite was called the Earth
ResourcesTechnology Satellite, or ERTS. Since its
launch on July 23, 1972, seven Landsats have
followed, with the latest, Landsat 8, lifting off on
February 11, 2013. Over the years successive
Landsats have not only carried better land-viewing
sensors, but they have created a valuable archive
of images that are being used to see how the land
is changing over the years. Landsat 8 carries
Operational Land Imager (OPI) andThermal
Infrared Sensor (TIRS) , which scans the Earth in
Eleven bands of visible and invisible light

4. Introduction
• Spacecraft: Landsat 8
• Carrier rocket: Atlas -V Rocket
• Launch date: 11th February 2013
• Launch site: Vandenberg Air Force
Base California
• Orbit: Sun-synchronous orbit at an
altitude of 705 km (438 mi)
• Equatorial crossing time: 10:00 a.m. +/-
15 minutes

5. Introduction Continue
 The Landsat program offers the longest
continuous global record of the Earth’s
surface
 Joint operation between NASA and USGS
 Landsat 8 officially began normal operations
on May 30, 2013
 Landsat 8 has collected about 400 scenes of
the Earth’s surface per day.
 Global coverage in 8 bands
 Swath width of Landsat 8 is 185km (115Miles)

6. Sensors
 The Landsat 8 satellite payload consists of
two specific sensors;
Operational Land Imager (OLI)
Thermal Infrared Sensor (TIRS)

7. Operational Land Imager (OLI)
 OLI will collect images using
nine spectral bands in different
wavelengths of visible, near-
infrared, and shortwave light to
observe a 185 kilometer (115
mile) wide swath of the Earth in
15-30 meter resolution covering
wide areas of the Earth's
landscape while providing
sufficient resolution to
distinguish features like urban
centers, farms, forests and
other land uses.

8. Thermal Infrared Sensor (TIRS)
 TheThermal Infrared Sensor
(TIRS) contains two thermal bands
(10 and 11), which measure land
surface temperature at 100-meter
resolution. (The product provided
is resampled and delivered as a 30-
meter image). In theTIRS thermal
bands, dark pixels represent cool
temperatures; light pixels
represent hot temperatures.
Thermal band data provide
important information about
water irrigation use in arid land, as
well as heat units in urban areas.

9. Resolutions
 Spatial Resolution
 Spectral Resolution
 Temporal Resolution
 Radiometric Resolution

10. Spatial Resolution
 9 spectral = 30 meters for Bands 1 to 7 and 9.
 Band 8 (panchromatic) = 15 meters.
 Thermal bands 10 , 11 = 100 meters
 New band 1 (ultra-blue) is useful for coastal
and aerosol studies.
 New band 9 is useful for cirrus cloud
detection.
 10 and 11 are useful in providing more
accurate surface temperatures

12. Temporal Resolution
 The entire Earth will fall within view once
every 16 days. I does Mean that Temporal
Resolution of Landsat 8 is 16 days. It
complete its ! Successive round in 16 days

13. Radiometric Resolution
 Radiometric resolution of Landsat 8 is 16 Bits.

14. Landsat 8 Enhancement
Landsat 8
images
normally looks
hazy before
processing.
Please have a
look of Landsat
8 images of Inle
Lake before and
after
processing.

15. Comparison with Landsat 7
The spectral bands (1 - 9) of the OLI sensor, while similar to Landsat 7’s ETM+
sensor, provide enhancement from prior Landsat instruments, with the addition of
two new spectral bands: a deep blue visible channel (band 1) specifically designed
for water resources and coastal zone investigation, and a new infrared channel
(band 9) for the detection of cirrus clouds. A new QualityAssurance band is also
included with each data product.This provides information on the presence of
features such as clouds, water, and snow.

18. 2.With Landsat 8's improved ability to detect variations in colors, the
waters of Lake Ontario can show sediment patterns as well as
potentially problematic algae, indicated by higher chlorophyll
concentrations.

19. 3. his Landsat 8 satellite image of some southern Japanese islands
includes Tanegashima (far right), from where the Global Precipitation
Measurement, or GPM, mission's Core Observatory is scheduled to
blast into orbit aboard a Japanese H-IIA rocket. This image was taken
on April 13, 2013
