GeoBrain DEM Explorerhttp://geobrain.laits.gmu.edu/
GeoBrain mobilizes NASA Earth Observing System (EOS) data and information through Web service and knowledge management technologies for higher-education teaching and research. The DEM Explorer, powered by GeoBrain, allows users to select and view Digital Elevation Model (DEM) data from the Shuttle Radar Topography Mission (SRTM), Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), and USGS Global Topographic Map at 30 arc-seconds (GTOPO30) collections.
Center for Spatial Information Science and Systems at George Mason University
A quick start demo is available online when you access GeoBrain DEM Explorer.
My World GIShttp://www.myworldgis.org/
My World GIS™ is a Geographic Information System (GIS) designed specifically for use in middle school through college classrooms. It was developed by the Geographic Data in Education (GEODE) Initiative at Northwestern University as part of a research program on the adaptation of scientific visualization and data analysis tools to support inquiry-based learning. My World GIS gives learners access to a variety of geographic data, enabling users to explore critical issues about the environment, geography, geology, demography, history, and much more. Its features include customizable display of layer variables, multiple geographic projections, table and map views of data, distance-measurement tools, and buffering and query operations.
The Geographic Data in Education (GEODE) Initiative at Northwestern University with funding from the National Science Foundation.
A free trial version is available for 45 days.
The following guides can be downloaded to help with the use of the program:
Data Source 1
Shuttle Radar Topography Mission (SRTM) Digital Elevation Data (DEM)http://www2.jpl.nasa.gov/srtm/
The Shuttle Radar Topography Mission (SRTM) obtained elevation data on a near-global scale to generate the most complete high-resolution digital topographic database of Earth. SRTM consisted of a specially modified radar system that flew onboard the Space Shuttle Endeavour during an 11-day mission in February of 2000.
SRTM coverage is global.

NOAA/WDC Historical Tsunami Database at NGDChttp://www.ngdc.noaa.gov/hazard/tsu_db.shtml
NOAA's National Geophysical Data Center (NGDC) and the co-located World Data Center for Geophysics and Marine Geology have compiled a unique set of tsunami-related products as part of a continuing program to support the interests of tsunami warning centers, engineers, oceanographers, seismologists, and the general public.
Historical tsunami coverage is global.
The data available at this site is from 2000 B.C. to present.

Oregon Geospatial DataOregon Spatial Data Library
The Oregon Spatial Data Library provides easy and convenient ways to find, access and share geospatial data. Datasets downloaded from this site include: Highways, State and County Boundaries, Place Names, and Tsunami Inundation Data.
Oregon geospatial data is limited to the state of Oregon.
The temporal coverage varies by dataset. Metadata for Oregon Geospatial data is available on the Web site.
