Historical Landsat Imagesfor Rivers and Streams

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.

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.

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.

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.
