The Free Geography Tools and several other geoblogs have pointed to the BBC runs an article the newly released world digital magnetic anomaly map: "The first global map of magnetic peculiarities - or anomalies - on Earth has been assembled by an international team of researchers. [...] The World Digital Magnetic Anomaly Map (WDMAM) is available through the Commission for the Geological Map of the World. The magnetic signature of the Earth's crust has been measured for many decades by a multitude of groups; but now, for the first time, the data has been combined to give a truly worldwide view of the phenomenon. [...] It represents a square grid of about five kilometers, so it's very coarse indeed. It is a starting point, and to go into detail, you can contact those organizations who have more detailed data on both the geology and mineral sources."

OneGeology: Mapping the Geology of the Planet 1 comment

GIS Lounge runs a short article on the OneGeology project aimed at mapping the geology of the planet. From the website: "The project's aim is to create dynamic digital geological map data for the world!
The target scale is 1:1 million. But the project will be pragmatic and accept a range of scales and the best available data.
The geological map data will be made available as a distributed web service, using the latest web feature mapping approach.
Geological Surveys will dynamically 'serve' the data for their territories to a web portal. The plan is to make it available through Google Earth and other dynamic map browsers." It's an international effort, with numerous governments participating, but the main (only?) major player absent is the United States.
