The Northwest is really leading the nation in this right now," said Melbourne, a geology professor at Central Washington University in Ellensburg, where PANGA is based.

PANGA's instruments are sophisticated variations on consumer GPS units, using the same constellation of satellites to triangulate positions. A decade ago, about 20 instruments were scattered between Oregon and the Canadian border. Each cost $50,000 and delivered data no more than once a day.

Today, 450 GPS units span the region, spitting out readings every second. Melbourne and his team are installing an additional 60 units this year. The price tag has dropped to about $8,000 for vastly more precise instruments.

Accuracy

If you can't see what you are looking for in 3 meters you should not be driving or at least let the seeing eye dog drive.
