 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. Water Dynamics Workshop, November 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.

 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 Water Dynamics Workshop, November Burlington Vermont

 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 Burlington Vermont

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 Burlington Vermont

 Four Bands Green µm. Red µm. Infrared µm. Infrared µm. Water Dynamics Workshop, November Burlington Vermont

Band 1 (Green)  Healthy vegetation Band 2 (Red)  Chlorophyll Water Dynamics Workshop, November Burlington Vermont

Near Infrared  Healthy green vegetation  Water lands Water Dynamics Workshop, November 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.
