Remote Sensing And
GIS Applications In
Glacier And Snow
Cover Studies
By
Swetha A
5WD12CGI15
Introduction
•Snow : Atmospheric water vapor frozen into ice crystals and
falling in light white flakes or lying on the ground as a white
layer.
•Glacier : are large masses of snow, recrystallized ice and rock
debris that accumulate in great quantities and begin to flow
outwards and downwards under the pressure of their own
weight
•Snow cover : ground covered with snow showing some depth
•Sea ice : Sea ice is simply frozen ocean water .Found in
remote polar oceans
What is the cryosphere?
• Some places on Earth are so cold that water is a solid—ice or
snow. Scientists call these frozen places of our planet the
"cryosphere." (snow , ice, glacier, sea ice, ice selves ice bergs,
frozen ground)
• The Arctic
• Antarctica
• And In between (snow on Mount Kilimanjaro is in
Africa )
Types of Glaciers
• Ice Sheets
• Ice Shelves
• Ice Caps
• Ice Streams
• Ice fields
• Mountain Glaciers
• Valley Glaciers
• Piedmont Glaciers
• Cirque Glaciers
• Hanging Glaciers
• Tidewater Glaciers
Types of snow cover
• New snow
• Firn
• Névé
• Old snow
• Seasonal snow
• Perennial snow
• Powder snow
Distribution of glaciers and ice around the world.
• The GLIMS
project (Global
Land Ice
Measurements
from Space) is
currently creating
a unique glacier
inventory storing
critical
information about
the extent and
rates of change of
the world's
estimated 160,000
glaciers.

• These snow cover maps are made
from observations collected by the
Moderate Resolution Imaging
Spectroradiometer (MODIS) on
NASA’s Terra satellite.
• Snow cover values range from
medium blue (greater than 0 percent)
to white (100 percent).
• Landmasses that do not sustain snow
cover and places where MODIS did
not collect data are gray or black.
• Because MODIS relies on visible light
to assess snow cover, the sensor
cannot collect data over the highest
latitudes of the Northern Hemisphere
during winter when no sunlight
reaches those regions.
MODIS ( Moderate Resolution Imaging
Spectroradiometer )
• Is a key instrument aboard the Terra and Aqua satellites.
• Terra was launched on December 18, 1999, and Aqua was launched on
May 4, 2002
• Terra's orbit around the Earth is timed so that it passes from north to south
across the equator in the morning, while Aqua passes south to north over
the equator in the afternoon.
• Terra MODIS and Aqua MODIS are viewing the entire Earth's surface
every 1 to 2 days, acquiring data in 36 spectral bands, or groups of
wavelengths
• 1,000-m, 500-m, and 250-m resolution spectral bands
• Works in visible region .
• The Moderate

Do glaciers and snow affect
people?
• Glaciers Provide Drinking Water
• Glaciers Irrigate Crops
• Glaciers Help Generate Hydroelectric Power
• Recreation
 Skiing and snowboarding
 Snowshoeing
 Snowmobiling
Are glaciers and snow
dangerous?
• Flooding Caused By A Glacier
• Avalanches From Glaciers
• The Threat Of Icebergs
• Snow Avalanches
• Ice Storm
• Blizzard
• Thunder Snow
Snow & glacier melting due to
• Global warming(0.32° increase)
• Greenhouse effect
• Climatic change
• Land use changes
• Deforestation (increase in atmospheric methane )

Glacier and snow

  • 1. Remote Sensing And GIS Applications In Glacier And Snow Cover Studies By Swetha A 5WD12CGI15
  • 2. Introduction •Snow : Atmospheric water vapor frozen into ice crystals and falling in light white flakes or lying on the ground as a white layer. •Glacier : are large masses of snow, recrystallized ice and rock debris that accumulate in great quantities and begin to flow outwards and downwards under the pressure of their own weight •Snow cover : ground covered with snow showing some depth •Sea ice : Sea ice is simply frozen ocean water .Found in remote polar oceans
  • 3. What is the cryosphere? • Some places on Earth are so cold that water is a solid—ice or snow. Scientists call these frozen places of our planet the "cryosphere." (snow , ice, glacier, sea ice, ice selves ice bergs, frozen ground) • The Arctic • Antarctica • And In between (snow on Mount Kilimanjaro is in Africa )

  • 12. • These snow cover maps are made from observations collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite. • Snow cover values range from medium blue (greater than 0 percent) to white (100 percent). • Landmasses that do not sustain snow cover and places where MODIS did not collect data are gray or black. • Because MODIS relies on visible light to assess snow cover, the sensor cannot collect data over the highest latitudes of the Northern Hemisphere during winter when no sunlight reaches those regions.
  • 13. MODIS ( Moderate Resolution Imaging Spectroradiometer ) • Is a key instrument aboard the Terra and Aqua satellites. • Terra was launched on December 18, 1999, and Aqua was launched on May 4, 2002 • Terra's orbit around the Earth is timed so that it passes from north to south across the equator in the morning, while Aqua passes south to north over the equator in the afternoon. • Terra MODIS and Aqua MODIS are viewing the entire Earth's surface every 1 to 2 days, acquiring data in 36 spectral bands, or groups of wavelengths • 1,000-m, 500-m, and 250-m resolution spectral bands • Works in visible region .
