The goals of OhioU-view are to promote the use of satellite and geospatial data in education; facilitate the use of satellite data to monitor areas of critical environmental concern; facilitate cooperation between education, and state and local governments in remote sensing and digital mapping; facilitate research and development in the applications of satellite data, and establish "virtual" centers for satellite and geospatial data synthesis and dissemination.

On this page you will find links to useful educational resources and research products developed here at Ohio University through the OhioView project.

These products are free for your use, and we encourage you to integrate them in your educational work. Some files are large and will require time to complete the download.
