GEO TIMES (May 2008)
Venturing to Venus Scientists suspect that Earth and Venus formed from the same parent material 4.5 billion years ago.

But what they don’t know is why Earth developed into a planet able to support life while Venus degenerated into a scorching wasteland. New missions should help scientists get to the bottom of this mystery.

Is It Better to Ask Permission or Beg Forgiveness?
Mark Dolezel & Janet Jackson understand the love/hate relationship that can exist when IT and GIS professionals use similar technologies for different reasons and to achieve different outcomes. This new GeoWorld column hopes to help readers "intersect" these professions whenever possible.
Twisting the Perspective of Map Surfaces
According to Josephy Berry, this month’s "Beyond Mapping" theme grabs some earlier concepts and adds an eye of newt and a twist of perspective to concoct a slightly shaken (not stirred) new perception of map surfaces.
A Mine Sweeper: Kentucky Delivers Maps of Abandoned Mines Online
Keeping track of abandoned mines isn’t easy, especially in a state with more than 30,000 of them. As famous for its rich coal-mining history as its horse racing, the commonwealth of Kentucky launched an ambitious tracking project: The Kentucky Mine Mapping Initiative.
Data, Data Everywhere and Not a Bit to Link
While we are awash in a sea of data, the use of relevant information often is restricted because of compatibility and/or security issues. The European Union is keenly aware of this paradox and the critical need to develop clear methodology to encourage greater use of e-government transactions. |
