They go into a computer program, along with satellite global positioning coordinates to map -- with precision -- the basic outline.
The satellite-borne phone will map the Earth with its 5 megapixel camera and conduct a number of scientific and engineering experiments, the most significant of which will be to hand total control of the spacecraft over to the Nexus.
To start with, they will use a combination of aerial photography, field measurements, and ground- and satellite-based sensors to compile a map of all the thermokarstic areas of Alaska.
Then he posted the satellite data online for any qualified geologist to map.
We had an airplane running flawlessly, we had real-time weather displayed on a large-screen map, and we had XM Satellite Radio to make the hours pass.
The Blue Force Tracker uses satellite signals from friendly forces in the field to map their positions -- reducing the risk of so-called "friendly fire" incidents.
It was a very public endeavor, including a website, with a blog, information about Gibbons and her journey, photos of her, and a map that showed her planned route and her satellite-tracked location at any given time.
Even now, when mapmakers have access to tools such as satellite images, there is still no objective and universally accepted map, argues Mr Brotton.
For drivers in unfamiliar areas, any site chosen can be plotted on a map using GPS, and maps can be changed to satellite, hybrid or terrain views.
Meanwhile, Dutch satellite navigation company TomTom, which provided the data for the new map system, told CNN it is not responsible for the way the maps work.
Mr. Agarwala started scrolling through the county planning department's map of parcel lines, turning to Google Maps to get a satellite view of streets that looked promising.
He then spotted the roads on the satellite image, along with the giant pipes, and added the station to his map.

Map data will continue to evolve-only a limited amount of high-resolution satellite imagery is currently available.
ENGADGET: Apple seeds iOS 6 beta 4 to developers: here's the changelog
Once there, they use aerial photography and remote cameras in combination with depth-finding and global-positioning satellite technology (as well as some first-hand testing of the waves) to measure the waves and map the contours of the ocean floor under the breaks.
Another possible draw: the introduction of a service called Sea Smart, a one-button emergency gizmo, comparable to OnStar for luxury autos, with a panic button that sends a signal via satellite every ten seconds and offers real-time tracking of the distressed vessel on a 3-D color map back at Sea Tow's headquarters.
