LOS ANGELES (AP) - NASA (news - web sites) has begun releasing the most accurate global map ever created - 3-D images of mountains, valleys and plains that were put together from a trillion measurements of the Earth's surface by a space shuttle crew last year.
The digital topographical maps were crunched from the 8 terabytes of data gathered during the 11-day Shuttle Radar Topography Mission, which ended in February 2000. The data - equal to 160 million pages of text - includes precise measurements of 80 percent of the Earth's land mass.
