NASA Space Geodesy Data for Precise Orbit Determination of Altimeter Satellites

NASA Space Geodesy Data for Precise Orbit Determination of Altimeter Satellites

Over the last 25 years, ocean radar altimeter satellites have revolutionized our understanding of the world’s oceans. Today six altimeter satellites from different national and international space agencies synoptically measure the ocean surface topography in order to determine how the ocean surface changes with time. The heart of the altimeter measurement is the precise determination of the orbit reference which ...

Destriping Landsat SLC Off Image

Destriping Landsat SLC Off Image

Landsat series of satellites have revolutionized the geospatial world. It can safely be assumed that Landsat 7 (Enhanced Thematic Mapper +) which was launched on  15th April 1999 was the most used satellite in the field of Geo Spatial Technologies. Landsat 7 has totally 8 bands of which 6 bands are of 30 meter resolution, PAN is of 15 meter ...

Thesis defence: Remote sensing of drylands hydrological pattern

Thesis defence: Remote sensing of drylands hydrological pattern

“Fine-scale remote sensing of woody vegetation in the drylands of the American southwest, coupled with automated pattern analysis, in an effort to detect the ubiquitous but subtle signal of an emergent eco-hydrological mechanism linked to climate sensitivity and collapse.” Presented in November 2008 at the University of Michigan School of Natural Resources and Environment by Hugh Stimson. More details here: ...
