Maps and Imaging Technologies
An introduction to what we can learn
about our planet
Variation in Gravity
El Nino and La Nina
Radar Image of Amazon
Image of World Vegetation Patterns
Passive Microwave Sensing
Salinities in Pacific Ocean
Satellite Image of Katrina
Infrared Image of Katrina
Land Sat Image of Deep Water Horizon
Spill
Photographic Image of DWH oil spill
Topographic of The Moon
Visible Light Image of Moon
So the question is
• What can we learn from these different types
of images
– of the same event
– About our planet
• Think for 1 minute
• Share with your table partner- Be prepared to
share with class
• IN OTHER WORDS, WHY ARE THESE
TECHNIQUES AND TECHNOLOGIES HELPFUL?
Now let’s read a little
• Set up 2 Cornell notes pages
• Each set of table partners will be assigned a
specific section to read and take notes from
• Go to assigned section of text
• You have 7 minutes to complete your reading and
notes with your table partner
• You will then switch partners and share the notes
from your team- 2 minutes per person
• You will switch 2 more times to gather all notes
Topographic Maps
• The lines translate three dimensional land
features into a two dimensional map
• Helpful in hiking and orienteering. They are also
used in land-use planning
• Rules!!- Contour lines do not cross. They can
merge at a vertical cliff. The closer together they
are the steeper the terrain. The father apart
contour lines are the more gradual the ascent
Topographic Symbols
– Index Contour Intervalcontour lines that have a
number written on
them. This number
indicates the elevation
of all points along the
line.
– Intermediate Contour
intervals- lines have no
number on them
– Depression-a decline in
elevation inside a rise for
example a volcanic
crater
– Supplementary Contour
Interval- dotted lines are
placed in areas where
elevation change is
minimal.
– Other frequent symbols
Blue= water, rivers, lakes
Red = land grids and
important roads
Black= smaller roads, trails,
boundaries
Green= vegetation
Examples
This is a picture of West Lost Lake
• Wouldn’t you love to take
a hike and see this place
for your self?
• It’s just a hop, skip and a
jump up into the Flat Tops
• I guess we had better find
out just how strenuous a
hike it is!
Your Turn
• With your table partner
• Get the following
materials:
–
–
–
–
a topographic map
a half sheet of paper
Ruler and piece of string
a direction sheet and
analysis questions.
HOMEWORK
• Complete the summary portion in your
Cornell Notes on Topographic Maps
• Complete the summary portion in your
Cornell Notes on LandSat and OSTM/Jason2
• Complete the summary portion in your
Cornell Notes on SeaBeam and Geologic Maps
• Each summary should be about 3-5 sentences
and should fit within the box/space
