Sentence examples for observing ground from inspiring English sources

Construction of the maps typically entails, in part, rectifying the satellite images to a geographic coordinate system, observing ground plots whose coordinates are obtained from Global Positioning System (GPS) receivers that are calibrated to the same geographic coordinate system, and then matching ground plots to image pixels containing the centers of the ground plots.

"What they did in the Plame case was to use the press's requirements for observing ground rules with sources as a way of making reporters enablers of a smear campaign.

Although the amounts of displacement on the direct traces were comparable with the estimated amounts of displacement shown in Fig. 10, for the reason of non-observing direct ground trace, we observed indirect traces of surface deformation and measured the amounts of displacement for cracks and damages on buildings and public works facilities.

Performing TIR measurements may make it possible to identify spectral features associated with the high radar backscattering efficiency of putative minerals and to differentiate between the proposed compositions (water ice, sulfur, and cold silicate glasses) for the high-latitude volatiles, something that cannot be done by ground based observing or near-infrared spectroscopy.

In principle, this implies the need to assimilate a greater density of observations; however, the distribution of ground-based observing instruments is often the most sparse at the highest latitudes, putting a greater premium on the assimilation of satellite data, e.g. from Langmuir probes and radio occultation techniques, or data derived from GPS tomography.

Can Earth observing missions be done "better, faster and cheaper"?

In contrast, most Earth observing satellites circle our planet within 22,300 miles.
