2. What is a landsat Program ?
 The Landsat Program is a series of
Earth-observing satellite missions jointly
managed by NASA and the U.S.
Geological Survey.

3. History
 Landsat was designed in 1960s by the combined
effort of NASA and US.
 Launched in 1972 as the 1st tailored Satellite,
specifically for broad scale observation of the
Earth’s Land areas.
 The program was initially called the Earth
Resources Technology Satellites Program, which
was used from 1966 to 1975. In 1975, the name
was changed to Landsat.

4. HOW LANDSAT WORKS
 It keeps a continuos observation of the land surface of
the globe.
 Their orbit goes from pole to pole and they capture a
new place and then every 16 -18 days and they start to
repeat .
 Landsat sensors record reflected and emitted energy
from Earth in various wavelengths of the
electromagnetic spectrum.
 Landsats 7 and 8 can record blue, green, and red light
in the visible spectrum as well as near-infrared, mid-
infrared, and thermal-infrared light that human eyes
cannot perceive
 Landsat records this information digitally and it is
downlinked to ground stations, processed, and stored
in a data archive.

6. Uses of landsat satellite
 Environmental impact assessment
 Detection of coal mine fire
 Biofuel crop monitoring
 Surface mine and reclamation efforts
 Detection of coal and mineral deposits

7. Sensors in landsat
 RBV - Return Beam Vidicon
 MSS - Multispectral scanner
 TM - Thematic mapper
 ETM - Enhanced thematic mapper
 ETM+ - Enhanced thematic mapper
plus

8. Continued …
 Landsat 1, 2 and 3 carried the Landsat
Multispectral Scanner (MSS).
 Landsat 4 and 5 carried both the MSS and
Thematic Mapper (TM) instruments.
 Landsat 7 uses the Enhanced Thematic Mapper
Plus (ETM+) scanner.
 Landsat 8 uses two instruments, the Operational
Land Imager (OLI) for optical bands and the
Thermal Infrared Sensor (TIRS) for thermal bands.

10. Case study
STUDY AREA : GODAVARI COAL
FIELDS
 The different land use classes mainly water body,
mining area, forest cover, built-up area, barren
land and agriculture land in Godavari coal field
area of southern India are identified and the
impact of land use/land cover change on the
environment are discussed.
 The land use/land cover changes in the Godavari
coal field area were analyzed for a period of 24
years i.e., from the year 1990 to 2014.
 The changes were detected on a 5-year time
interval using Landsat-5 TM, Landsat-8 OLI and
TIRS satellite images and the human impact on
the landscape are discussed.

13. Conclusion
 The study shows that there is a direct impact of
mining on forest cover along with other factors.
 This study helps in the decision making for land
reclamation and land management in the Godavari
coal field area of India.
