Lewis and Clark Geosystem: Pioneering Remote Sensing for Education and Research
The Lewis and Clark Geosystem is a groundbreaking collaborative research project launched in 2004 by GCS and NASA. This innovative initiative provides an extensive collection of remote sensing images to a diverse audience, including K-16 educators, scholarly researchers, and the general public interested in geospatial data.

Key Features of the Lewis and Clark Geosystem
- Integration of Esri Services: The project seamlessly integrates Esri services with NASA’s core data node, allowing users to access a comprehensive array of remote sensing images and geospatial datasets.
- Unique Data Blend: This innovative platform combines historical cartographic products with NASA’s vast archive of modern satellite imagery, including datasets from Landsat 5 TM, Landsat 7 ETM+, ATLAS, and Hyperion. This unique blend enhances the depth and scope of available data.
- Educational Resources: By making remote sensing imagery easily accessible, the Lewis and Clark Geosystem supports various educational initiatives and research efforts, enriching the understanding of geospatial concepts among students and researchers alike.

Enhancing Access to Geospatial Data
The Lewis and Clark Geosystem marks a significant advancement in the availability of remote sensing data, effectively bridging the gap between historical geography and modern satellite technology. This project not only enriches educational resources but also promotes interdisciplinary research, fostering a greater appreciation for geospatial science.
Lewis and Clark Bicentennial: GCS Supports National Geospatial Dataset
In conjunction with the Lewis and Clark Bicentennial Commemoration, GCS continues to pioneer nationally distributed applications and research related to the geography of this important exploration. GCS Research served as a National Geospatial One Stop (GOS II) portal Channel Manager, facilitating access to geospatial datasets.

Geo.data.gov is a geographic information system (GIS) portal, known as the Geospatial One-Stop (GOS), that provides a public gateway to improve access to geospatial information and data under the Geospatial One-Stop E-Government initiative. The Geospatial One-Stop is one of 24 E-Government initiatives sponsored by the Federal Office of Management and Budget (OMB), aimed at enhancing government efficiency and improving citizen services.
The Lewis and Clark Geosystem distributed application is currently maintained and published on the GOS II portal, ensuring continued access to vital geospatial data.
