Tools and Data

Tool 1

GeoBrain DEM Explorer

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.

Tool 2

My World GIS

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.

Data Source 1

Shuttle Radar Topography Mission (SRTM) Digital Elevation Data (DEM)

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.

Geospatial Coverage

SRTM coverage is global.

Data Temporal Coverage

February 2000
