Thursday, April 19, 2007

7:00 p.m. to 8:00 p.m. Eastern time

Virtual Globes for Geospatial Visualizations in the Classroom

Presented by: Galen ScottNational Oceanic & Atmospheric Administration (NOAA)

National Ocean Service (NOS)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. How can Virtual Globes be used to engage 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.

What Scientific Applications for Virtual Globes can you

think of?

Type your ideas on the direct 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.

Your ideas of Potential uses in Classroom

Ask for volunteers to suggest classroom topics

1. 2. 3.

4. 5. 6.

7. 8. 9.

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 ReportsUse the ‘add placemark’ feature to plot places visited by the children.

• Locality studiesInvestigate 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.
