Variations

Digital Elevation Model (DEM) data can be used in a variety of investigations. Below are a few variations to try with DEM data:

Other Data

Obtain river, population, or other geographical data formatted for GIS applications, and analyze the data within a hazard mitigation context. For example: How would you prepare your community for such events as a major forest fire or volcanic eruption? Other hazard data is available for the state of Oregon. Many states and organizations have geospatial data libraries.

Other Techniques

After completing this activity, take a field trip to a local coastal region or river valley and continue discussion about flood run-up and hazard preparation.

Other Tools

GeoBrain DEM and Contour data can be imported into any GIS and most visualization tools such as My World GIS and ArcGIS. Students can complete some sections of this lesson using only the online visualization tools. The Oregon data and historical tsunami data used in this lesson are also available as KML files, which can be viewed in Google Earth.

Advanced users may be interested in the GeoBrain Image Analysis System.
