National Geodetic Survey (NGS)
Did you attend the Geodesy & GPS
Symposium at the NSTA national conference?
YES
NO
Learning Objectives
At the end of this session participants
should be able to explain:
1.
What is a Virtual Globe?
2.
What online data resources are available for
classroom use?
3.

students?
What is a Virtual Globe?
•
•
A 3D software model of the Earth or another world.
Provides the ability to move around in the virtual
environment by changing the viewing angle and
position.
Overlays multiple views on the surface of the
Earth, including:
•
–
–
–
Geographical features – Mountain, Valleys & Oceans
Man-made features - Roads and Buildings
Representations of abstract data – Populations,
Temperature, & Weather Patterns

The First 21st Century
Technological Revolution?
• Free geospatial visualization & analysis for everyone
• Virtual Globes have proliferated due to widely
available high-resolution satellite imagery and aerial
photography.
• Virtual Globes are changing the way information is
shared.
Functionality of Virtual Globes:
What do they do?
• Go anywhere in the world from anywhere in
the world, instantly.
• Pan, Tilt, & Zoom into 3D images
• Search for anything on earth – your house,
your school, famous landmarks, corner deli
• View images, text and 3D models from others
• Measure between points
• Label ANYTHING you find
• Upload your own images, text and 3D models
to share with others
Creating and Sharing Your
Own Content
• Placemarks
• Digital photos
• GPS tracks
• 3D models (using SketchUp)
Creating and Sharing Content
Create and share models of your school or
proposed development projects around your
community, like this one from a student at
Kealakehe High School in Kona, Hawaii
Thanks Larry.

messaging window
Some examples of Scientific
Applications for Virtual Globes
• Post disaster imagery can be shared in
near real-time enabling first responders
and evacuated people to see what’s
happening and where.
• Enables students and scientists to view
and study complex environmental
phenomena in context.
• Annotated maps and fly-through movies
discuss environmental and social issues
for education and advocacy.

Some other ideas for use in the
classroom
•
Fly from one locality to another.
What oceans are crossed? How far is it? Which direction was the
flight in? How many borders do various countries have?
•
Journey along a river from source to mouth.
•
Trace the life cycle of a Product: pair of jeans or a cup of coffee
•
Vacation Reports
Use the ‘add placemark’ feature to plot places visited by the children.
•
Locality studies
Investigate geographical features nearby or famous places around
the world.

Virtual Globe Applications
for Archaeology
• National Geographic Article
NASA World Wind helps to solve an ancient mystery.
Where is the Ithaca described in such detail in Homer's Odyssey?
The mystery has baffled scholars for over two millennia because Homer's descriptions
bear little resemblance to the modern Greek island called Ithaki.
But what if this mismatch has occurred not because of geographical errors by the poet,
but because of geological changes in the landscape? What could have altered the layout
of the Greek islands since the time of the Trojan War around 1200 BC?
Using tools like World Wind scientists have been able to reconstruct the former layout of
these islands and provide a compelling solution to the long established enigma of
Homer’s Ithaca.
Timeline and use of visualizations in finding Ithaca.
