  1. Historical Landsat Images for Rivers and Streams Juan de Dios Barrios, M.S. Research Associate Nick J. Rahall Appalachian Transportation Institute and James O. Brumfield, Ph. D. College of Science Marshall University November, 9, 2008

  2. Geospatial Sciences Water Dynamics Workshop, November 2008. Burlington Vermont • Geographic Information Systems • Computer software tools for analyzing geo-referenced spatial data. • Remote Sensing Systems • Sensor Systems used to collect information some remote distance from the subject. • Global Positioning Systems • Earth Orbital Satellites Systems used to determined position on the earth’s surface.

  3. Geospatial Science Principles Water Dynamics Workshop, November 2008. Burlington Vermont The power of Geospatial Sciences is based in the capability to integrate different geospatial data into a comprehensive geoanalytical system. This can result in the development of proper applications for scientific, social and cultural models.

  4. Landsat Multispectral Scanner (MSS) Water Dynamics Workshop, November 2008. Burlington Vermont • A historical record of the Earth’s land surface from July 1972 to July1976. • First Satellite, Landsat I • Launched 7/23/1972 • Named Earth Resources Technology (ERTS-1). Later NASA changed the name to Landsat 1 • Second Satellite, Landsat II • Launched 7/22/75 • Named Earth Resources Technology (ERTS-B). Later NASA changed the name to Landsat 2

  5. Satellite Ranging • Altitude 920 Km • 18 day coverage • 185 km wide image swaths • Sun-synchronous Crossing times • Landsat 1 8:30 am • Landsat 2 9:00 am With Landsat I and II operational 9 day imaging cycles Water Dynamics Workshop, November 2008. Burlington Vermont

  6. Satellite System Landsats I and II • Return Beam Vidicon (RBV) • RBV did not have film down linked to ground receiving stations • Multispectral Scanner (MSS) down linked to ground receiving stations stored on tape and converted to scanned film. Water Dynamics Workshop, November 2008. Burlington Vermont

  7. MSS Sensor • Four Bands • Green 0.5-0.6 µm. • Red 0.6-0.7 µm. • Infrared 0.7-0.8 µm. • Infrared 0.8-1.1 µm. Water Dynamics Workshop, November 2008. Burlington Vermont

  8. High Resolution Thematic Mapper Multispectral Data with Digital Elevation Models Water Dynamics Workshop, November 2008. Burlington Vermont

  9. High Resolution Thematic Mapper Multispectral Data with Digital Elevation Models • Band 1 (Green) • Healthy vegetation • Band 2 (Red) • Chlorophyll Water Dynamics Workshop, November 2008. Burlington Vermont

  10. High Resolution Thematic Mapper Multispectral Data with Digital Elevation Models • Near Infrared • Healthy green vegetation • Water lands Water Dynamics Workshop, November 2008. Burlington Vermont

  11. Combinations Water Dynamics Workshop, November 2008. Burlington Vermont • In a Near Infrared, Red and Green (false color) combination • Water bodies appear brown to blue to black in color. • Deep clear water appears dark blue to black in color, while sediment-laden or shallow waters appear lighter in color. • Urban areas appear blue-gray in color.

  12. Cairo Illinois BAND FIVE BAND SIX Water Dynamics Workshop, November 2008. Burlington Vermont

  13. Cairo Illinois N 37-05 W088-53 Water Dynamics Workshop, November 2008. Burlington Vermont

  14. St. Louis Missouri BAND FOUR BAND FIVE Water Dynamics Workshop, November 2008. Burlington Vermont

  15. St. Louis Missouri N39-02 w091-09 Water Dynamics Workshop, November 2008. Burlington Vermont

  16. Archived MSS Image Data Water Dynamics Workshop, November 2008. Burlington Vermont Marshall University College of Science has access to imagery from July 1972 to July 1976 of Landsat I and Landsat II providing an opportunity for global coverage. Only selected digital information is available in the form of tiff files. Availability of data is currently under evaluation. The data can be made available for educational research or academic uses.
