My April column addressed the vertical movement at the NOAA CORS Network (NCN). The values at the sites indicate the potential movement of marks in the area of the ...

Gravity field modeling and geoid determination are critical tasks in geodesy and Earth sciences, providing insights into the Earth’s mass distribution and its gravitational potential. Researchers ...

[UPDATE (April 5, 2011): It turns out some of the descriptions I used below to describe a geoid were not accurate. I refer you to this page at the University of Oklahoma for a good description. I’ve ...

Orthometric height support (survey-grade elevations) enables Arrow GNSS receivers to collect high-accuracy, survey-grade vertical data with any data-collection software. Eos Positioning Systems Inc.

This is a preview. Log in through your library . Abstract Moho depth or simply, Moho, in general, describes the boundary between the earth’s crust and the mantle and is a very important geophysical ...

It may look like a mangled lump of Play-Doh, but this colorful object is actually the most accurate digital model yet of Earth's gravity field, scientists say. Released last week, the gravity map is ...
