State-Based Resources: Investigate
- Part A: Data from the Global Positioning System
|
|
Obtain a GPS time series for a station nearest
South Carolina. Record the directions and rates of motion in cm/yr for the station
nearest your community.

Investigate - Part B: Data from a Computer Model

You will need to know the latitude and longitude of your school
in decimal format. Find your school (or another familiar place)
on your local topographic map. Use the map to identify the latitude
and longitude of your school.

U.S. Geological Survey topographic maps were digitized and
are now available on the Web.
Find topographic maps by
place name, latitude and longitude, or UTM coordinates under the
Get A Map section. Allows you to download topographic maps (including
USGS maps) for free, at various scales (from 1:100,000 to 1:24,000).

- Excellent web sites that describe how GPS works can be found
on the EarthComm web site.
Very comprehensive
site explores scientific methods before and after the advent
of GPS, as well as a review of how GPS works and what are
its applications. A good introductory site.
This
site reviews the basics of plate motions and introduces the
science of geodesy and using GPS to track current plate movements.
Includes an image of a GPS satellite.
- Vist the EarthComm web site for the address of animated images
of the motions of lithospheric plates.
Allows you to view
plate motions from the past 200 million years, as well as
predicted motions 25 million years into the future.
Information
on plate tectonics, including animations of plate motions
for the past 750 million years.
