The objective is to improve the WWW accessibility (including interoperability) and usefulness of global geoscience data needed to address many societal issues including mitigation of hazards, meeting resource requirements, and climate change. It is to make web-accessible the best available geological and other geoscience data worldwide at the best possible scales. Over the 944 data sets, services and maps, the most popular is at 1:1 million scale but numerous maps can be found at 1/500,000 and 1/250,000 as well.
