Modern Exploration of the Lewis and Clark Expedition

About this technology

Overview

The Lewis and Clark Geosystem is an online collection of private, state, local, and Federal data resources associated with the geography of the Lewis and Clark Expedition. Data was compiled from key partners including NASA's Stennis Space Center, the U.S. Army Corps of Engineers, the U.S. Fish and Wildlife Service, the U.S. Geological Survey (USGS), the University of Montana, the U.S. Department of Agriculture Forest Service, and from a collection of Lewis and Clark scholars. The Stennis contribution to the Lewis and Clark Geosystem consisted of providing access to a variety of different satellite resources. Most notably, the system employs comprehensive national land coverage from the Moderate Resolution Imaging Spectroradiometer, a key instrument aboard NASA's Terra and Aqua satellites. It also employs imagery from the Advanced Thermal and Land Applications Sensor remote sensing instrument flown on the Stennis Lear jet to show select campsites along the Lewis and Clark Trail, as well as Landsat 5 TM (Thematic Mapper) data and the highly accurate Landsat 7 ETM+ (Enhanced Thematic Mapper Plus) coverage of the trail. Stennis also worked with a Lewis and Clark historian, Dr. Robert Bergantino, and GCS Research LLC, a geospatial information technology firm based out of Missoula, Montana, that has a Space Act Agreement with Stennis.
